Eppendorf Research plus single-channel pipette, variable, 100–1000 µL, blue, 3123000063
Varying sample volumes within the same volume range require a pipette that can be adjusted quickly and without the need for tools. The Eppendorf Research plus single-channel pipette, in its variable 100–1000 µL blue version, meets precisely this requirement, with 1 µL increments and a spring-loaded tip cone that reduces the force required for tip loading. It is designed for workstations where dilution series or different sample volumes are used within the same batch.Typical applicationsThe Eppendorf Research plus 100–1,000 µL is suitable for, amongst other things:Media changes in cell cultureBuffer preparations and reagent dispensing in the medium-volume rangeSample aliquoting and sample preparationFilling reaction vessels and cuvettesFeatures and handlingAll Research-plus pipettes up to 1 mL are fitted with a spring-loaded tip cone, which reduces the force required for tip changes. Within the Eppendorf pipette range, Research-plus is one of the lightest models, an advantage during many consecutive pipetting steps. For cleaning and maintenance, the lower section with the Fortron PerfectPiston can be quickly disassembled without tools.Eppendorf provides a user-adjustment feature for the Research-plus range, known as secondary adjustment, which allows the pipette to be set for a liquid other than water without permanently altering the factory setting.Selection guide within the Research plus rangeThe volume ranges vary significantly across the variable Research-plus models. The following overview shows neighbouring variable models from the same range:VolumeColour codeMPN1–10 mLturquoise31230000802–20 µLlight grey31230000982–20 µLyellow312300003930–300 µLorange3123000101The appropriate volume in each individual case depends on the actual sample quantities and reagent volumes involved in the respective step. Selecting a volume that is too large reduces relative accuracy at the lower end of the scale, whilst selecting a volume that is too small necessitates several pipetting steps instead of a single one.Comparing Research plus, Reference 2 and XplorerAnyone choosing between the three Eppendorf manual pipette ranges should first consider the operation. The Research plus is adjusted via a mechanical adjustment wheel, with no electronics and no display, making it robust and low-maintenance. The Reference 2 replaces the adjustment wheel with a single-button operation featuring a digital display, which is practical for laboratories with frequently changing volumes and multiple users sharing the same device. The Xplorer and Xplorer Plus go one step further, pipetting electronically programmed sequences, with password protection included in the Plus version. For a clearly defined volume range in routine work, the mechanical Research Plus range remains the simplest choice.Differentiation within the Research plus rangeIf the volume range of this pipette does not fully meet your requirements, it is worth considering neighbouring Research plus models, for example the Eppendorf Research plus single-channel pipette, variable (1–10 mL), 3123000080 Eppendorf Research plus G pipette, single-channel, variable, 2–20 µL, light grey, epT.I.P.S. box, 3123000098. This allows you to put together a suitable combination of several volume ranges without having to switch to a different product line.Use, storage and maintenanceThe upper and lower sections can be autoclaved together at 121 °C and 1 bar overpressure for 20 minutes; it is not necessary to dismantle the lower section for this. The filter sleeve and protective filter are autoclaved separately. No re-lubrication is required after autoclaving; a gravimetric accuracy check is recommended afterwards. The pipette is stored without transport packaging at temperatures between –5 and 45 degrees Celsius and relative humidity of 10 to 95 per cent; during operation, the temperature range is 5 to 40 degrees Celsius within the same humidity range. Warranty claims are handled via the relevant Eppendorf authorised partner; claims are excluded for damage resulting from misuse, unauthorised opening of the upper section, and wear and tear on typical wear parts.Fixed volume or variable settingA variable-volume pipette is worthwhile whenever different volumes within the same range are required during a workflow, for example when carrying out dilution series or handling varying sample volumes. The adjustment wheel allows for adjustment without tools and without changing equipment. If, on the other hand, only a single volume is pipetted on a permanent basis, a fixed-volume pipette from the same range eliminates the risk of accidental misadjustment.Frequently asked questionsCan the 100–1000 µL version be sterilised in an autoclave?Yes, the upper and lower sections can both withstand 121 degrees Celsius, 1 bar overpressure and a dwell time of 20 minutes; it is not necessary to dismantle the lower section for this. The filter sleeve and protective filter are autoclaved separately.How is accuracy checked after autoclaving?Re-greasing is not required; however, Eppendorf still recommends a gravimetric check after autoclaving to confirm accuracy.How is the volume set on the variable model?Via the mechanical adjustment wheel on the pipette head, without a display or electronics. The set value is retained until the next adjustment.Which pipette tips are compatible with the Eppendorf Research plus 100–1000 µL?According to the operating instructions: epT.I.P.S. blue 71 mm (50–1000 µL).Is the pipette an in vitro diagnostic device?According to the operating instructions, the Research plus range is designed for the low-contamination transfer of liquids, including samples from the human body and reagents within the context of an in vitro diagnostic application as defined by Directive 98/79/EC.To whom should warranty claims be addressed?To the relevant Eppendorf authorised dealer. Excluded are damages resulting from misuse, unauthorised opening of the upper part, and wear and tear of typical wear parts.Can the pipette be readjusted if it deviates from the factory setting?According to the manufacturer, secondary calibration is provided for the Research-plus range. Details are set out in a separate Eppendorf calibration document, the full text of which was not available at the time of writing.What does the IVD marking on the Research-plus range signify?The user manual generically refers to the pipette as an in vitro diagnostic device within the meaning of Directive 98/79/EC, for the entire Research-plus range.

Brand Transferpette S Starter Kit Standard, 3 Pipettes 0.5-10 / 10-100 / 100-1000 µl, DE-M, 705893
Anyone who wants to equip a laboratory with several volume ranges in one go rarely needs just a single pipette. The Brand Transferpette S Starter Kit Standard bundles 3 variable single-channel pipettes of 0.5-10 / 10-100 / 100-1000 µl in one set and thus covers in one go what would otherwise require several individual orders, ready for use directly in the stand and typically suitable for initial laboratory equipment with the three most frequently used volume ranges in everyday microbiological and molecular biological work. This makes the commonly used combination of small, medium and large volume available immediately. All the pipettes included can be operated one after another without getting used to a different handling.3 pipettes for the complete rangeThe Starter Kit Standard combines 3 Transferpette S single-channel pipettes with variable volume: the D-10 for 0.5-10 µl with an increment of 0.01 µl, the D-100 for 10-100 µl with an increment of 0.1 µl and the D-1000 for 100-1000 µl with an increment of 1 µl. Together the devices cover the range 0.5-10 / 10-100 / 100-1000 µl. A matching pipette tip size is defined for each pipette, included in the set as 1x TipBox 0.5-20 µl, 1x TipBox 2-200 µl, 1x TipBox 50-1000 µl.Precision under German legal metrologyAll pipettes in the set carry the DE-M marking under German legal metrology, and the accuracy testing is based on DIN EN ISO 8655 with three test points per volume range (100, 50 and 10 percent of the nominal volume). At the respective nominal volume, the accuracy A lies, depending on the model, between ±1 % and ±0.6 %, a level of accuracy that matters in dilution series and quantitative analyses. The accuracy A describes the deviation of the mean dispensed volume from the nominal value, the coefficient of variation CV the scatter of several repetitions at the same volume, both values increase towards the lower end of a volume range.One-handed operation and tool-free adjustmentFor series work, each pipette in the set is designed for one-handed operation, including a lock (UNLOCK/LOCK) against accidental adjustment. A deviation from the factory setting can be corrected directly and without tools using the Easy Calibration function.Autoclavable fully assembledSterile working is possible with every pipette in the set: it can be autoclaved completely, at 121 degrees Celsius and 2 bar, with a holding time of at least 15 minutes according to DIN EN 285, without having to be dismantled beforehand.Quality certificate and warranty includedA quality certificate (Performance Certificate) documents the testing of the pipettes in the Starter Kit Standard. A three-year warranty applies to the single-channel pipettes of the entire Transferpette S series.Which laboratory this combination suitsFor a newly equipped laboratory without a known focus, a broad basic equipment makes more sense than specialising in one volume window. With a small, a medium and a large range, the Starter Kit Standard covers the combination most frequently requested in practice, before the actual requirements become apparent in operation.Advantage of the set over individual procurementChoosing the Starter Kit Standard replaces 3 individual orders and the different delivery times that come with them. Since all pipettes come from the same series, operation is identical on every device, which helps especially at workstations with changing staff. The 3 shelf holders supplied hold all 3 pipettes within easy reach between two applications, instead of leaving them lying loose on the laboratory bench.Typical applicationsInitial laboratory equipment with the three most frequently used volume ranges in everyday microbiological and molecular biological work. This makes the commonly used combination of small, medium and large volume available immediately.Dilution series and reagent addition across several volume rangesInitial equipment for newly set up workstations as well as training and further educationReplacement equipment for a second workstation with the same volume spectrumTechnical detailsCompositionTransferpette S variable, single-channel, 3-piece Starter KitVolume range D-100.5-10 µl, increment 0.01 µlVolume range D-10010-100 µl, increment 0.1 µlVolume range D-1000100-1000 µl, increment 1 µlOperationOne-handed operation, volume lock UNLOCK/LOCKAdjustmentEasy Calibration, tool-free, adjustment slider under the label windowSterilisationAutoclavable fully assembled at 121 °C, 2 bar, at least 15 minutes according to DIN EN 285MarkingDE-MScope of delivery1x Transferpette S variable, D-10 (0.5-10 µl)1x Transferpette S variable, D-100 (10-100 µl)1x Transferpette S variable, D-1000 (100-1000 µl)1x TipBox 0.5-20 µl, 1x TipBox 2-200 µl, 1x TipBox 50-1000 µl, filled3 shelf holders1x quality certificate1x silicone greaseIndividual requirements & procurement serviceFor deviating requirements, LT Laborhandel carries both the individual models of the Transferpette S series and further sets with a different volume combination.

Eppendorf Multipette M4 Hand-operated Dispenser with Bracket, Mechanical, 4982000012
This version of the Multipette M4 comes with a mount that can be fitted either on the wall or in the pipette carousel. If you wish to keep the dispenser within easy reach at a fixed workstation, there is no need to purchase the mount separately, as it is already included with this item. Same dispensing technology as the basic model Like the standard M4, this variant also operates on the direct displacement principle: the piston of the Combitip advanced is moved directly by the device, so there is no need for a separate piston in the dispenser. A code on the Combitip and a sensor ring in the device automatically recognise the tip size being used. Mounting bracket for wall or carousel The supplied mount is suitable for either wall mounting or installation in a pipette carousel. For workstations with multiple dispensing devices, this reduces the need to search for the right unit, and ensures the M4 does not sit loose on the bench between two runs. For viscous and aqueous media A ViscoTip with a 10 mL volume is also available for viscous samples; for standard aqueous applications, the Combitip advanced range covers the entire volume range from 1 µL to 50 mL, with volumes from 0.1 mL to 50 mL. Selection guide: M4, E3 or E3x If you need a Multipette without ever having to worry about a battery, the M4 is the right choice for you. It requires no charging cycles; according to the manufacturer, a single button cell lasts around two years and powers only the automatic volume detection. On the other hand, if you work in a setting where volumes vary within the same Combitip size, or if you wish to programme a series with different increments, the motorised E3 or E3x is a better choice: both can be operated via the display and rocker switch, whilst the M4 is adjusted purely mechanically using a scale. According to the user manual, the E3 and E3x have the same specifications for volume range, battery and test conditions. Both are based on the same device platform. Product family overview: Multipette, Research plus and Xplorer A Multipette is a repeat dispenser: it draws a larger volume of liquid from the Combitip advanced in a single aspiration and then dispenses it in several equal portions without having to aspirate again in between. This is worthwhile whenever the same volume needs to be dispensed repeatedly into many vessels, such as when filling a microtitre plate. A Research plus or Xplorer pipette, on the other hand, is a piston-stroke pipette based on the air-cushion principle: It draws up a single volume at a time using an epT.I.P.S. tip and dispenses it once before drawing up again; this is the right choice for single volumes or small series with varying quantities. Because, with the Multipette’s direct displacement principle, the liquid flows exclusively through the Combitip and does not come into contact with the device, the Multipette is also suitable for viscous, foaming or volatile media, where an air cushion in the pipette tip would lead to inaccuracies. For viscous samples, the M4 also offers a ViscoTip with a 10 mL volume. Typical applications Permanent workstation set-ups where the dispenser is to be mounted within easy reach at all times Batch filling of test tubes or microtitre plates Addition of reagents in sample preparation and quality control Combination with a pipette carousel when several dispensers are stored together Use and maintenance When a new Combitip advanced is attached, the M4 automatically reads the coding on the tip body via a sensor ring in the device and adjusts itself to the appropriate volume range; there is no need for manual switching. After use, the Combitip is disposed of together with its integrated piston; the device itself does not come into contact with the dispensed liquid. Information regarding the autoclavability of the dispenser housing itself is available on request; only the Combitips advanced and the ViscoTip, as single-use items, are affected by the sterilisation requirements.

Regulatory information The Multipette M4 features battery-powered volume detection and is therefore subject to WEEE registration requirements. We will provide the WEEE registration number on request. Frequently Asked Questions Do I need to reset the volume when changing the Combitip size? No, a code on the Combitip and a sensor ring in the device automatically detect the tip size. Is the Multipette M4 suitable for viscous liquids? Yes, a ViscoTip with a 10 mL volume is also available for this purpose. How long does the M4’s battery last? According to the manufacturer, a 3 V button cell powers the volume detection for around two years. What is the total volume range covered by the M4? 1 µL to 50 mL; depending on the Combitip Advanced size used, the range is between 0.1 mL and 50 mL. Can I also dispense single volumes with the M4, as with a piston-type pipette? No, the M4 is a repeat dispenser for repeated, equal-sized portions from a single sample; for single volumes, a Research-plus or Xplorer pipette is the more suitable choice.

Eppendorf Research plus single-channel pipette set, pack of 3, 0.5–10 µL / 10–100 µL / 100–1000 µL, 3123000900
Those who switch between several volume ranges in their day-to-day laboratory work often find themselves using three separate pipettes rather than just one. The Research-plus Set 3123000900 brings together precisely this combination: one pipette for 0.5–10 µL, one for 10–100 µL and one for 100–1000 µL, each colour-coded and supplied with matching epT.I.P.S. tips. The set is suitable for workstations where different volume ranges are regularly used in the same experiment, for example in molecular biology or when preparing dilution series.Typical applicationsThe Eppendorf Research plus 0.5–10 µL / 10–100 µL / 100–1000 µL is suitable, amongst other things, for:Filling reaction vessels and cuvettesMedia changes in cell culturePCR reactions and dilution seriesPipetting small volumes into microtitre platesSample aliquoting and sample preparationEquipment and handlingFor volumes up to 1 mL, Eppendorf’s Research-plus range features a spring-loaded tip cone, which makes attaching and ejecting the pipette tip noticeably easier. The pipette is one of the lightest in the Eppendorf range, which makes a noticeable difference to user comfort during long pipetting runs. The Fortron PerfectPiston is housed in a base that can be dismantled without tools, making it practical for cleaning and maintenance.If the pipetting result deviates from the expected accuracy – for example, when using a liquid other than water – the pipette can be readjusted via a user-defined setting without losing the original factory setting.A comparison of Research plus, Reference 2 and XplorerResearch plus, Reference 2 and Xplorer together form the Eppendorf manual pipette family, but differ significantly in terms of operation. Research plus adjusts the volume mechanically via a setting wheel, without any electronics at all. Reference 2, on the other hand, uses a digital display with one-button operation and is particularly suitable for workstations where volumes change frequently. Xplorer and Xplorer plus feature electronic, programmable pipetting, are battery-operated and, in the Plus version, offer additional functions such as dilution or sequential dispensing. Research plus, on the other hand, stands out as the lightest of the three ranges and is the easiest to handle during continuous use.Differentiation within the Research plus rangeIf this pipette’s volume range does not fully meet your requirements, it is worth considering neighbouring Research plus models, for example the Eppendorf Pipette Research plus G, 3-pack, Option 3, 100–1000 µL / 0.5–5 mL / 1–10 mL, incl. epT.I.P.S. boxes, 3123000926 Eppendorf Pipette Research plus G, single-channel, fixed, 200 µL blue, 3124000091. This allows you to put together a suitable combination of several volume ranges without having to switch to a different product line.Use, storage and maintenanceThe upper and lower sections can be autoclaved together at 121 °C and 1 bar overpressure for 20 minutes; it is not necessary to dismantle the lower section for this. The filter sleeve and protective filter are autoclaved separately. No re-lubrication is required after autoclaving; a gravimetric accuracy check is recommended afterwards. The pipette is stored without transport packaging at temperatures between –5 and 45 degrees Celsius and relative humidity of 10 to 95 per cent; during operation, the temperature range is 5 to 40 degrees Celsius within the same humidity range. Warranty claims are handled via the relevant Eppendorf authorised partner; damage resulting from misuse, unauthorised opening of the upper section and wear and tear on typical wear parts are excluded.Set or single pipetteA set of three covers a wider volume range than a single pipette and is intended for workstations where users regularly switch between the three volume ranges included. If only one specific volume range is required on a permanent basis, the corresponding individual pipette from the Research-plus range may be sufficient.Frequently asked questionsIs the Eppendorf Research plus 0.5–10 µL / 10–100 µL / 100–1000 µL autoclavable?Yes. The upper and lower sections can be autoclaved together at 121 degrees Celsius and 1 bar gauge pressure for 20 minutes without the lower section needing to be dismantled.

With five variable single-channel pipettes, the Brand Transferpette S Pipette Package 2 covers the complete range from 0.5 µl to 5 ml and so provides a full initial equipment in one go, for PCR and molecular biology workstations as well as for preparative sample preparation, ready for use in the practical bench stand and without having to collect additional individual pipettes. Five pipettes for the complete working range Pipette Package 2 combines five Transferpette S single-channel pipettes with variable volume: the D-10 for 0.5 to 10 µl with an increment of 0.01 µl, the D-100 for 10 to 100 µl with an increment of 0.1 µl, the D-200 for 20 to 200 µl with an increment of 0.2 µl, the D-1000 for 100 to 1,000 µl with an increment of 1 µl and the D-5000 for 500 to 5,000 µl with an increment of 5 µl. Together, the five devices cover the range from 0.5 µl to 5 ml without gaps, from the smallest PCR reactions to larger volumes in preparative sample preparation. Matching tip sizes are also defined for each of the five pipettes, from 0.5 to 20 µl for the D-10, through 2 to 200 µl for D-100 and D-200, up to 50 to 1,000 µl for the D-1000 and 500 to 5,000 µl for the D-5000. Precision under German weights and measures law All five pipettes carry the DE-M marking under German weights and measures law as well as the CE marking, and the accuracy testing follows DIN EN ISO 8655. At the respective nominal volume, the D-10 achieves an accuracy A of up to ±1 % with a coefficient of variation CV of up to 0.5 %. The four larger models D-100, D-200, D-1000 and D-5000 each have an accuracy A of up to ±0.6 % and a coefficient of variation CV of up to 0.2 %, a level of accuracy that counts particularly in quantitative analyses and dilution series. True one-handed operation for fatigue-free work Volume adjustment, pipetting and tip ejection can all be carried out with one hand on the Transferpette S, so there is no change of grip during serial work. A lockable volume setting with UNLOCK and LOCK position prevents the set volume from being changed accidentally during intensive use, a detail that pays off above all in long pipetting series in everyday laboratory work and lowers the error rate in repeated pipetting steps. Tool-free adjustment with Easy Calibration If the factory setting drifts, every pipette can be adjusted directly using the Easy Calibration function without any additional tool. A red adjustment slider in the display window shows when the factory setting has been changed, so it is visible at a glance whether the pipette is still running on its original calibration or has been readjusted. Autoclavable fully assembled For use in sterile areas, all five pipettes can be autoclaved fully assembled, at 121 degrees Celsius and 2 bar with a holding time of at least 15 minutes to DIN EN 285. Dismantling before sterilisation is therefore not necessary, which significantly reduces the effort for recurring sterilisation cycles in the laboratory. A tidy workstation with the carousel bench stand The bench stand supplied holds up to six devices as a carousel and so keeps the workstation clear even with five pipettes. All devices stand within reach and protected between two uses, instead of lying loose on the laboratory bench or contaminating each other. Quality certificate and warranty included Pipette Package 2 comes with a quality certificate (Performance Certificate) that documents the testing of the individual pipettes and can be filed directly into your own quality assurance. A three-year warranty applies to the single-channel pipettes of the Transferpette S series. Typical applications PCR reactions and master mix pipetting in molecular biology with D-10 and D-100 ELISA and other microtitre plate applications with D-100 and D-200 Dilution series and buffer preparation in general laboratory routine with D-200 and D-1000 Preparative sample preparation and larger volumes, for example when transferring reagents or preparing stock solutions, with D-1000 and D-5000 Initial laboratory equipment for newly set up workstations as well as for education and training, where different volume ranges are needed at the same time Technical details Model seriesTransferpette S, variable, single-channel, 5-piece package Volume range D-100.5-10 µl, increment 0.01 µl Volume range D-10010-100 µl, increment 0.1 µl Volume range D-20020-200 µl, increment 0.2 µl Volume range D-1000100-1,000 µl, increment 1 µl Volume range D-5000500-5,000 µl (0.5-5 ml), increment 5 µl Recommended tips D-100.5-20 µl Recommended tips D-100 / D-2002-200 µl Recommended tips D-100050-1,000 µl Recommended tips D-5000500-5,000 µl Accuracy (A) D-10 at nominal volume≤ ±1 % Coefficient of variation (CV) D-10 at nominal volume≤ 0.5 % Accuracy (A) D-100 / D-200 / D-1000 / D-5000 at nominal volume≤ ±0.6 % Coefficient of variation (CV) D-100 / D-200 / D-1000 / D-5000 at nominal volume≤ 0.2 % OperationOne-handed operation for volume setting, pipetting and tip ejection Volume lockUNLOCK / LOCK AdjustmentEasy Calibration, tool-free, red adjustment slider in display window SterilisationAutoclavable fully assembled at 121 °C, 2 bar, holding time at least 15 minutes to DIN EN 285 MarkingDE-M, CE Test standardDIN EN ISO 8655 (accuracy testing) Warranty3 years on single-channel pipettes Scope of delivery 1x Transferpette S, variable, D-10 (0.5-10 µl) 1x Transferpette S, variable, D-100 (10-100 µl) 1x Transferpette S, variable, D-200 (20-200 µl) 1x Transferpette S, variable, D-1000 (100-1,000 µl) 1x Transferpette S, variable, D-5000 (500-5,000 µl) 4x TipBox pipette tips, filled: 1x 0.5-20 µl, 1x 2-200 µl, 1x 50-1,000 µl, 1x 0.5-5 ml 1x bench stand (carousel for 6 devices) 1x quality certificate (Performance Certificate) 1x silicone grease Individual requirements & procurement service Anyone who does not need the complete 5-piece equipment will also find smaller Transferpette S starter kits at LT Laborhandel, for example in the combinations Micro, Midi, Macro or Standard, with a reduced pipette selection for narrower requirements or a smaller budget.

Eppendorf Research plus single-channel pipette set, pack of 3, 2–20/20–200/100–1000 µL, 3123000918
The Research-plus 3-pack Option 2 comprises three mechanical single-channel pipettes with consecutive volume ranges: 2 to 20 µL, 20 to 200 µL and 100 to 1,000 µL. For a laboratory requiring the same basic equipment for pipetting volumes ranging from microlitres to millilitres, this set covers the three most common routine volumes in a single order. Three volume ranges, one pipetting principle All three pipettes in the set operate on the same mechanical air-cushion principle as the Research-plus series, with a spring-loaded tip cone up to 1 mL and a Fortron PerfectPiston in the quick-release lower section. Anyone already familiar with one of the three pipettes in the set will find the other two easy to use straight away. Each pipette in detail The 2 to 20 µL pipette (increment 0.02 µL, epT.I.P.S. yellow 53 mm) achieves a systematic measurement error of 1.0 per cent or 0.2 µL at 20 µL and a random measurement error of 0.3 per cent or 0.06 µL. The 20 to 200 µL pipette (increment 0.2 µL, epT.I.P.S. yellow 53 mm) achieves a systematic measurement error of 0.6 per cent (or 1.2 µL) and a random measurement error of 0.2 per cent (or 0.4 µL) at 200 µL. The 100 to 1,000 µL pipette (1 µL increment, epT.I.P.S. blue 71 mm) achieves a systematic measurement error of 0.6 per cent, or 6.0 µL, and a random measurement error of 0.2 per cent, or 2.0 µL, at 1,000 µL. Tests are carried out in accordance with ISO 8655, with ten determinations per volume, and using water in accordance with ISO 3696. Autoclavable for daily use The upper and lower parts can be autoclaved together at 121 °C and 1 bar overpressure for 20 minutes; the flasks do not need to be re-greased afterwards. The filter sleeve and protective filter are autoclaved separately. Selection guide: for which laboratory equipment this set is intended This set is suitable for workstations that switch between small volumes in the double-digit microlitre range and larger volumes in the millilitre range during routine operations, for example when preparing dilution series or preparing reagents of different concentrations. Those who, on the other hand, work predominantly in the sub-microlitre range or in the millilitre range above 1 mL will find more suitable individual volumes in the Reference 2 or Xplorer ranges, which feature a different operating logic. Product range overview: Research plus, Reference 2 and Xplorer Research plus, Reference 2 and Xplorer are all piston-driven pipettes based on the air-cushion principle and each dispense a single volume using an epT.I.P.S. tip. The difference lies in their operation: Research plus is the basic mechanical model with a selection dial and, according to the manufacturer, the lowest weight and lowest operating forces in the Eppendorf pipette family. Reference 2 is operated via a single button and features a four-digit display with a magnifying window for reading volumes from any angle. Xplorer is the electronic version with a selection dial, rocker switch and display, which also allows volumes to be locked and batch runs to be programmed. Anyone who manually sets many different volumes in a single day and values a particularly light weight in the hand will find the Research plus well suited to their needs. For repetitive dispensing of the same volume into many vessels from a single sample, however, a Multipette (M4, E3 or E3x) is the more suitable choice, as it operates on the direct displacement principle and does not re-aspirate after each dispense. Materials and environmental conditions The upper section is made of modified polypropylene (PP), polycarbonate (PC) and polyetherimide (PEI), whilst the lower section is additionally made of PVDF, PPS, PEEK, PTFE, EPDM, silicone and stainless steel. The pipettes are operated at 5 to 40 °C and 10 to 95 per cent relative humidity, and are stored without transport packaging at minus 5 to 45 °C. According to the manufacturer, all volumes up to 1 mL feature a spring-loaded tip cone, which reduces the force required to attach and eject the tip during tip changes. Typical applications Sample preparation with varying volumes ranging from a few microlitres to one millilitre Preparation of dilution series across several orders of magnitude Basic equipment for new workstations where several volume ranges are required simultaneously Routine applications in sample preparation and reagent addition Technical details Pipettes includedResearch plus variable, 2–20 µL / 20–200 µL / 100–1,000 µL TipsepT.I.P.S. yellow 53 mm (2–20 µL and 20–200 µL), epT.I.P.S. blue 71 mm (100–1,000 µL) Increment0.02 µL (2–20 µL), 0.2 µL (20–200 µL), 1 µL (100–1,000 µL) Systematic measurement error 2–20 µL at 20 µL1.0% / 0.2 µL Systematic measurement error 20–200 µL at 200 µL0.6 per cent / 1.2 µL Systematic measurement error 100–1,000 µL at 1,000 µL0.6% / 6.0 µL Random measurement error 2–20 µL at 20 µL0.3% / 0.06 µL Random measurement error 20–200 µL at 200 µL0.2% / 0.4 µL Random measurement deviation 100–1,000 µL at 1,000 µL0.2% / 2.0 µL Autoclavability121 °C, 1 bar gauge pressure, 20 minutes, assembled Operating environmental conditions5 to 40 °C, 10 to 95 % relative humidity Contents 3 x Research plus single-channel pipettes, variable (2–20 µL, 20–200 µL, 100–1,000 µL) epT.I.P.S. boxes Frequently asked questions Are all three pipettes in the set autoclavable? Yes, the upper and lower parts can be autoclaved together at 121 °C, 1 bar overpressure, for 20 minutes; the filter sleeve and protective filter are autoclaved separately. Do I need to re-lubricate the pistons after autoclaving? No, according to the operating instructions, re-lubrication of the pistons is not necessary; a gravimetric check is recommended. What kind of day-to-day laboratory work is this set designed for? For workstations that regularly switch between microlitre and millilitre volumes, such as when carrying out dilution series or sample preparation, without having to purchase a separate pipette for each application. Do the tips of the three pipettes fit together? No, each pipette in the set uses its own epT.I.P.S. size to match its volume range; the tips are not designed to be mixed and matched between the three models.

Brand Transferpette S Variable Single-Channel Pipette, 100-1000 µl, DE-M, 705880
When transferring culture medium for cell culture runs of different sizes, the volume needed varies between a few hundred microlitres and one millilitre depending on vessel size. The Brand Transferpette S variable D-1000 covers 100-1000 µl with an increment of 1 µl, without having to keep a separate device for every amount.Continuously adjustable with 1 µl incrementThe Transferpette S variable 100-1000 µl (model D-1000) covers the volume range 100-1000 µl in steps of 1 µl. The volume is set with a dial without tools, and a lockable position (UNLOCK/LOCK) prevents accidental adjustment during serial work. To match the volume range, Brand recommends the pipette tip size 50-1000 µl. In total, the variable Transferpette S series comprises ten volume sizes from 0.1 µl to 10 ml, so a suitable model from the same range can be combined for almost every working range. One range smaller is the Transferpette S variable 20-200 µl (D-200, MPN 705878). One range larger follows the Transferpette S variable 0.5-5 ml (D-5000, MPN 705882).Accuracy to DIN EN ISO 8655Tested to DIN EN ISO 8655 at three volume levels: at the full nominal volume, the pipette achieves an accuracy A of up to ±0.6 % and a coefficient of variation CV of up to 0.2 %, at half the nominal volume ±0.8 % and 0.3 % respectively, and at the lower end, at one tenth of the nominal volume, ±3 % and 0.6 % respectively. The three test points show that the accuracy decreases towards the lower end of the volume range, an effect that occurs with every air displacement pipette and should be taken into account when choosing the suitable model. The DE-M marking confirms the testing under German weights and measures law. The accuracy A describes the deviation of the average dispensed volume from the target value, and the coefficient of variation CV the scatter of several repetitions at this volume.Tool-free adjustment with Easy CalibrationThe Easy Calibration function allows readjustment directly on the pipette, without tools, using an adjustment slider under the label window with volume offset. A changed factory setting becomes visible through a red adjustment slider in the display window.Fully autoclavableFor sterile applications, the pipette can be autoclaved fully assembled, as a complete unit, at 121 degrees Celsius and 2 bar, with a holding time of at least 15 minutes to DIN EN 285, and dismantling is not required.Variable or fixed: which design fitsCulture vessels of different sizes need different amounts of medium, which makes the variable Transferpette S D-1000 the right choice. If the same vessel format is always supplied with the same amount, a Transferpette S Fix from the same range offers simpler operation. For the D-1000 with its range of 100-1000 µl, the specific working step therefore decides whether variable or fixed is the more suitable design.Quality certificate and warranty includedEvery pipette is supplied with a quality certificate (Performance Certificate), which can be filed into your own quality assurance. A three-year warranty applies to the single-channel pipettes of the Transferpette S series.Typical applicationsTransferring culture medium for cell culture runs of different sizesTransferring reagents and preparing stock solutionsBuffer preparation in general laboratory routineInitial laboratory equipment when a medium volume range is needed flexiblySerial work over a longer period with several volume levelsTechnical detailsModelTransferpette S variable, D-1000Volume range100-1000 µlIncrement1 µlRecommended tip size50-1000 µlAccuracy (A) at 100/50/10 % of nominal volume≤ ±0.6 % / ±0.8 % / ±3 %Coefficient of variation (CV) at 100/50/10 % of nominal volume≤ 0.2 % / 0.3 % / 0.6 %OperationOne-handed operation, volume lock UNLOCK/LOCKAdjustmentEasy Calibration, tool-free, adjustment slider under label windowSterilisationFully autoclavable at 121 °C, 2 bar, at least 15 minutes to DIN EN 285MarkingDE-MScope of delivery1x Transferpette S variable 100-1000 µl (D-1000)1x quality certificate1x silicone greaseIndividual requirements & procurement serviceIf a different volume range is needed in addition, it is worth looking at the neighbouring models of the Transferpette S series or at the starter kits with several ranges in one set.

Brand Transferpette S Pipette Package 1, 5 Pipettes 0.1 µl to 1 ml, DE-M, 705896
Anyone who wants to equip a laboratory with several volume ranges in one go rarely needs just a single pipette. The Brand Transferpette S Pipette Package 1 bundles 5 variable single-channel pipettes from 0.1 µl to 1 ml in one combination and so covers at once what would otherwise take several individual orders, ready for use in the stand and typically suited to a complete initial laboratory equipment across five volume ranges, from PCR volumes to preparative sample preparation. This reduces the coordination effort compared with several individual orders with different delivery times.5 pipettes for the complete rangePipette Package 1 combines 5 Transferpette S single-channel pipettes with variable volume: the D-2.5 for 0.1-2.5 µl with an increment of 0.002 µl, the D-10 for 0.5-10 µl with an increment of 0.01 µl, the D-20 for 2-20 µl with an increment of 0.02 µl, the D-200 for 20-200 µl with an increment of 0.2 µl and the D-1000 for 100-1000 µl with an increment of 1 µl. Together, the devices cover the range 0.1 µl to 1 ml. A matching pipette tip size is defined for each pipette, included in the set as 3x TipBox.Precision under German weights and measures lawAll pipettes in the set carry the DE-M marking under German weights and measures law, and the accuracy testing follows DIN EN ISO 8655 with three test points per volume range (100, 50 and 10 percent of the nominal volume). At the respective nominal volume, the accuracy A is between ±1.4 % and ±0.6 % depending on the model, a level of accuracy that matters for dilution series and quantitative analyses. The accuracy A describes the deviation of the average dispensed volume from the target value, and the coefficient of variation CV the scatter of several repetitions at the same volume. Both values increase towards the lower end of a volume range.One-handed operation and tool-free adjustmentEvery pipette in the set is operated with one hand, from volume setting to tip ejection, protected by a lock (UNLOCK/LOCK). Adjustment is tool-free using Easy Calibration, and an adjustment slider under the label window shows a changed factory setting.Autoclavable fully assembledEvery pipette in the set withstands autoclaving in the assembled state, as a complete unit, at 121 degrees Celsius and 2 bar, with a holding time of at least 15 minutes to DIN EN 285, and dismantling before sterilisation is not required.Quality certificate and warranty includedA quality certificate (Performance Certificate) is enclosed with the set, which can be filed directly into your own quality assurance. The single-channel pipettes of the Transferpette S series are covered by a three-year warranty.Which laboratory this combination suitsA laboratory that covers both PCR preparation in very small volumes and larger sample preparation up to 1 ml usually cannot manage with a single starter kit. With five volume ranges, Pipette Package 1 closes the gap between the smaller kits and so covers a complete molecular biology workstation in one go.Advantage of the set over individual procurementFor a newly set up laboratory, Pipette Package 1 covers 5 volume ranges in a single process, instead of collecting them one by one. All devices come from the same series and are operated in the same way, which makes training easier. The bench stand supplied keeps all 5 pipettes within reach between two uses, instead of leaving them lying loose on the laboratory bench.Typical applicationscomplete initial laboratory equipment across five volume ranges, from PCR volumes to preparative sample preparationDilution series and adding reagents across several volume rangesInitial laboratory equipment for newly set up workstations as well as education and trainingSetting up an additional workstation without several individual ordersTechnical detailsCombinationTransferpette S variable, single-channel, 5-piece pipette packageVolume range D-2.50.1-2.5 µl, increment 0.002 µlVolume range D-100.5-10 µl, increment 0.01 µlVolume range D-202-20 µl, increment 0.02 µlVolume range D-20020-200 µl, increment 0.2 µlVolume range D-1000100-1000 µl, increment 1 µlOperationOne-handed operation, volume lock UNLOCK/LOCKAdjustmentEasy Calibration, tool-free, adjustment slider under label windowSterilisationAutoclavable fully assembled at 121 °C, 2 bar, at least 15 minutes to DIN EN 285MarkingDE-MScope of delivery1x Transferpette S variable, D-2.5 (0.1-2.5 µl)1x Transferpette S variable, D-10 (0.5-10 µl)1x Transferpette S variable, D-20 (2-20 µl)1x Transferpette S variable, D-200 (20-200 µl)1x Transferpette S variable, D-1000 (100-1000 µl)3x TipBox, filled1x bench stand1x quality certificate1x silicone greaseIndividual requirements & procurement serviceIf this combination does not fit completely, LT Laborhandel offers further Transferpette S sets and individual models with a different volume combination.

Eppendorf Research plus single-channel pipette, variable, 20–200 µL, yellow, 3123000055
Varying sample volumes within the same volume range require a pipette that can be adjusted quickly and without the need for tools. The Eppendorf Research plus single-channel pipette, in its variable 20–200 µL version (yellow), meets precisely this requirement, with 0.2 µL increments and a spring-loaded tip cone that reduces the force required for tip loading. It is designed for workstations where dilution series or different sample volumes are used within the same batch.Typical applicationsThe Eppendorf Research plus 20–200 µL is suitable for, amongst other things:Standard work in molecular biologyDilution series and reagent dispensing in routine laboratoriesSample aliquoting into reaction vesselsPreparing reaction mixtures in cell cultureFeatures and handlingFor volumes up to 1 mL, Eppendorf’s Research plus range features a spring-loaded tip cone, which makes attaching and ejecting the pipette tip noticeably easier. As the lightest pipette in the Eppendorf range, the Research plus reduces hand strain during prolonged batch work. The lower section, featuring a Fortron PerfectPiston, can be quickly dismantled without tools for maintenance and cleaning.Eppendorf provides a user adjustment feature for the Research plus range, known as secondary adjustment, which allows the pipette to be set for a liquid other than water without permanently altering the factory setting.Selection guide within the Research-plus rangeThe volume ranges vary significantly across the variable Research plus models. The following overview shows neighbouring variable models from the same range:VolumeColour codeMPN1–10 mLturquoise31230000802–20 µLlight grey31230000982–20 µLyellow312300003930–300 µLorange3123000101The appropriate volume in each individual case depends on the actual sample quantities and reagent volumes involved in the respective step. Selecting a volume that is too large reduces relative accuracy at the lower end of the scale, whilst selecting a volume that is too small necessitates several pipetting steps instead of a single one.Comparing Research plus, Reference 2 and XplorerAnyone choosing between the three Eppendorf manual pipette ranges should first consider the operation. The Research plus is adjusted via a mechanical adjustment wheel, with no electronics and no display, making it robust and low-maintenance. The Reference 2 replaces the adjustment wheel with a single-button operation featuring a digital display, which is practical for laboratories with frequently changing volumes and multiple users sharing the same device. The Xplorer and Xplorer Plus go one step further, pipetting electronically programmed sequences, including password protection on the Plus model. For a clearly defined volume range in routine work, the mechanical Research Plus range remains the simplest choice.Differentiation within the Research plus rangeIf the volume range of this pipette does not fully meet your requirements, it is worth considering neighbouring Research plus models, for example the Eppendorf Research plus single-channel pipette, variable (1–10 mL), 3123000080 Eppendorf Research plus G pipette, single-channel, variable, 2–20 µL, light grey, epT.I.P.S. box, 3123000098. This allows you to put together a suitable combination of several volume ranges without having to switch to a different product line.Use, storage and maintenance121 °C, 1 bar overpressure, 20 minutes: the pipette can be autoclaved whilst fully assembled; the lower section does not need to be dismantled for this, only the filter sleeve and protective filter are placed separately in the autoclave. There is no need to re-lubricate the pistons afterwards, although a gravimetric check is still advisable. Without transport packaging, storage is intended at temperatures between –5 and 45 degrees Celsius and relative humidity between 10 and 95 per cent; during operation, the range is 5 to 40 degrees Celsius with the same humidity range. The relevant Eppendorf authorised dealer is the point of contact for warranty matters, excluding wear parts and damage resulting from misuse or the upper part being opened without authorisation.Fixed volume or variable settingThose who switch between several volumes within the same range in their day-to-day work – for example, when carrying out dilution series or handling different sample volumes per batch – will find a variable-volume pipette more flexible than using several fixed-volume devices. For a single, recurring value, however, a fixed-volume pipette from the Research-plus range is the better choice, as it prevents the adjustment wheel from being turned in the first place.Frequently asked questionsIs the Eppendorf Research plus 20–200 µL autoclavable?Yes. The upper and lower sections can be autoclaved together at 121 degrees Celsius and 1 bar overpressure for 20 minutes without the lower section needing to be dismantled. The filter sleeve and protective filter are autoclaved separately.Does the pipette need to be recalibrated after autoclaving?It is not necessary to re-lubricate the pistons after autoclaving. However, a gravimetric accuracy check is still recommended afterwards.How is the volume set on the variable model?Via the mechanical adjustment wheel on the pipette head, without a display or electronics. The set value is retained until the next adjustment.Which pipette tips are compatible with the Eppendorf Research plus 20–200 µL?According to the epT.I.P.S. operating instructions: yellow 53 mm (2–200 µL).Is the pipette an in vitro diagnostic device?According to the operating instructions, the Research plus range is designed for the low-contamination transfer of liquids, including samples from the human body and reagents within the context of an in vitro diagnostic application as defined by Directive 98/79/EC.To whom should warranty claims be addressed?To the relevant Eppendorf authorised dealer. Excluded are damages resulting from misuse, unauthorised opening of the upper part, and wear and tear on typical wearing parts.Can the pipette be readjusted if it deviates from the factory setting?According to the manufacturer, secondary calibration is provided for the Research-plus range. Details are set out in a separate Eppendorf calibration document, the full text of which was not available at the time of writing.What does the IVD marking on the Research-plus range signify?The user manual generically refers to the pipette as an in vitro diagnostic device within the meaning of Directive 98/79/EC, for the entire Research-plus range. No product-specific confirmation was available at the time of writing.Technical detailsRangeEppendorf Research plusModelvariableVolume20–200 µLIncrement0.2 µLColour codeyellowCompatible pipette tipepT.I.P.S. yellow 53 mm (2–200 µL)Test volume 20 µLSystematic measurement error 2.5%/0.5 µLRandom measurement error 0.7%/0.14 µLTest volume 100 µLSystematic measurement error: 1.0%/1.0 µLRandom measurement error 0.3%/0.3 µLTest volume 200 µLSystematic measurement error 0.6%/1.2 µLRandom measurement error 0.2%/0.4 µLStandardTest in accordance with ISO 8655Contents1 Eppendorf Research plus single-channel pipette (20–200 µL, yellow)Individual requirements & procurement serviceFor suitable pipette tips, spare parts or additional volume ranges from the Research plus range, LT Laborhandel provides support via its own procurement service at lt-laborhandel.de/service.
Eppendorf Multipette E3 Hand Dispenser, Electronic, 4987000010
The Multipette E3 adapts the direct displacement principle of the mechanical M4 to a motorised device: the piston of the Combitip advanced is driven by a motor, whilst dispensing is controlled via the display and rocker switch. For batch runs with varying volumes within the same Combitip size, this saves steps compared with the mechanical version. Three operating modes for the basic tasks in a series Dispensing (Dis) delivers the same volume continuously into a series of vessels; automatic dispensing (Ads) draws up several portions in succession; pipetting (Pip) covers the classic single-volume operation. According to Eppendorf’s manufacturer’s specifications, these are the three basic modes of the E3; more advanced applications such as titration or sequential dosing are reserved for the E3x. Rechargeable battery with micro-USB charging A 1,200 mAh lithium-ion battery powers the E3; it is charged via the supplied mains adaptor with a Micro-USB interface. According to the manufacturer’s specifications, a full charge lasts around five hours under test conditions, with at least 500 samples and 10,000 dispensing steps; the battery is ready for use again in around two hours. Fine resolution across the entire Combitip range With 5,000 possible dispensing volumes and increments starting at 100 nL for the smallest Combitip size, the E3 covers the entire range from 1 µL to 50 mL with greater precision than would be possible with a purely mechanical scale. Selection guide: M4, E3 or E3x If you need a Multipette without ever having to worry about a battery, the M4 is the right choice for you. It requires no charging cycles; according to the manufacturer, a single button cell lasts around two years and powers only the automatic volume detection. On the other hand, if you work in a setting where volumes vary within the same Combitip size, the motorised E3 is the better choice: With its three basic modes, dispensing, automatic dispensing and pipetting, it covers classic repetitive and single-dispense tasks and can be operated via a display and rocker switch, whilst the M4 is adjusted purely mechanically using a scale. According to Eppendorf’s manufacturer’s specifications, anyone who also requires titrations, sequential dispensing steps or aspiration/dispensing in a single operation will find these advanced modes only on the E3x, not on the E3. Product range overview: Multipette, Research plus and Xplorer A Multipette is a repeat dispenser: it draws a larger volume of liquid from the Combitip advanced using a single tip and then dispenses it in several equal portions without having to aspirate again in between. This is worthwhile whenever the same volume needs to be dispensed repeatedly into many vessels, such as when filling a microtitre plate. A Research plus or Xplorer pipette, on the other hand, is a piston-stroke pipette based on the air-cushion principle: It draws up a single volume at a time using an epT.I.P.S. tip and dispenses it once before drawing up again; this is the right choice for single volumes or small series with varying quantities. Because, with the Multipette’s direct displacement principle, the liquid flows exclusively through the Combitip and does not come into contact with the device, the Multipette is also suitable for viscous, foaming or volatile media, where an air cushion in the pipette tip would lead to inaccuracies. For viscous samples, the M4 also offers a ViscoTip with a 10 mL volume. Typical applications Continuous dispensing of the same volume in ‘Dis’ mode for dilution series and plate filling Aspiration of multiple portions in Ads mode for rapid batch processing Single-volume dispensing in Pip mode Addition of reagents in diagnostics, quality control and research Use and maintenance When a new Combitip advanced is fitted, the Multipette automatically recognises the tip size used and sets the appropriate volume range. The desired operating mode can be selected directly on the device via the display, without the need for external software. After use, the Combitip is disposed of together with its integrated piston; the instrument itself does not come into contact with the dispensed liquid. The battery is charged using the supplied mains adaptor with a micro-USB interface; according to the manufacturer’s specifications, a full charge is sufficient for at least 500 aspirations and 10,000 dispensing cycles under test conditions. We can provide information on the autoclavability of the dispenser housing itself on request. Only the Combitips advanced, as disposable items, are affected by the sterilisation requirements.

Regulatory information As a battery-powered, motorised dispensing device with a mains power supply, this product is subject to WEEE registration requirements. We will provide the WEEE registration number on request. Frequently asked questions Do I need to reset the volume when changing the Combitip size? No, the device automatically recognises the tip size. What is the difference between the E3 and the E3x? The E3 covers the three basic modes: dispensing, automatic dispensing and pipetting. According to Eppendorf’s manufacturer’s specifications, the E3x also offers additional operating modes such as titration, sequential dispensing and aspiration/dispensing, which are not available on the E3. How long does the battery last in everyday use? According to the manufacturer’s specifications under test conditions, around 5 hours for at least 500 aspirations and 10,000 dispensing steps; it takes approximately 2 hours to charge. What operating modes are available on the E3? Dispensing (Dis) for continuous dispensing of the same volume, automatic dispensing (Ads) for drawing up multiple portions, and pipetting (Pip) for single volumes. Is the E3 suitable for foaming or volatile liquids? As the direct displacement principle ensures that the liquid flows exclusively through the Combitip, the risk of inaccuracies caused by air pockets is lower than with piston-type pipettes.

Brand Transferpette S Variable Single-Channel Pipette, 10-100 µl, DE-M, 705874
When transferring supernatants during protein purification, the volume varies from fraction to fraction, depending on how much supernatant actually has to be removed after centrifugation. The Brand Transferpette S variable D-100 covers 10-100 µl with an increment of 0.1 µl and can be adjusted by dial without tools.Continuously adjustable with 0.1 µl incrementThe Transferpette S variable 10-100 µl (model D-100) covers the volume range 10-100 µl in steps of 0.1 µl. The volume is set with a dial without tools, and a lockable position (UNLOCK/LOCK) prevents accidental adjustment during serial work. To match the volume range, Brand recommends the pipette tip size 2-200 µl. In total, the variable Transferpette S series comprises ten volume sizes from 0.1 µl to 10 ml, so a suitable model from the same range can be combined for almost every working range. One range smaller is the Transferpette S variable 5-50 µl (D-50, MPN 705873). One range larger follows the Transferpette S variable 20-200 µl (D-200, MPN 705878).Accuracy to DIN EN ISO 8655Tested to DIN EN ISO 8655 at three volume levels: at the full nominal volume, the pipette achieves an accuracy A of up to ±0.6 % and a coefficient of variation CV of up to 0.2 %, at half the nominal volume ±0.8 % and 0.4 % respectively, and at the lower end, at one tenth of the nominal volume, ±3 % and 1 % respectively. The three test points show that the accuracy decreases towards the lower end of the volume range, an effect that occurs with every air displacement pipette and should be taken into account when choosing the suitable model. The DE-M marking confirms the testing under German weights and measures law. The accuracy A describes the deviation of the average dispensed volume from the target value, and the coefficient of variation CV the scatter of several repetitions at this volume.Tool-free adjustment with Easy CalibrationIf the factory setting deviates, the pipette can be adjusted directly using the Easy Calibration function, without any additional tool. An adjustment slider under the label window with volume offset shows when the factory setting has been changed. A red adjustment slider in the display window shows whether the pipette is still running on its original calibration or has been readjusted.Fully autoclavableThe pipette withstands autoclaving as a complete unit, at 121 degrees Celsius and 2 bar, with a holding time of at least 15 minutes to DIN EN 285, in the assembled state, and dismantling before sterilisation is not necessary.Variable or fixed: which design fitsWhen transferring supernatants, the amount actually available is never exactly the same, which suits the variable Transferpette S D-100. If, on the other hand, the same volume always has to be transferred in a standardised protocol, a Transferpette S Fix from the same range is sufficient. For the D-100 with its range of 10-100 µl, the specific working step therefore decides whether variable or fixed is the more suitable design.Quality certificate and warranty includedA quality certificate (Performance Certificate) is enclosed, which can be filed directly into your own quality assurance. The single-channel pipettes of the Transferpette S series are covered by a three-year warranty.Typical applicationsTransferring supernatants in protein purification with a fluctuating volumeELISA and other microtitre plate applications with variable requirementsDilution series in general laboratory routineInitial laboratory equipment for newly set up workstationsQuality assurance with documented, variable volume settingTechnical detailsModelTransferpette S variable, D-100Volume range10-100 µlIncrement0.1 µlRecommended tip size2-200 µlAccuracy (A) at 100/50/10 % of nominal volume≤ ±0.6 % / ±0.8 % / ±3 %Coefficient of variation (CV) at 100/50/10 % of nominal volume≤ 0.2 % / 0.4 % / 1 %OperationOne-handed operation, volume lock UNLOCK/LOCKAdjustmentEasy Calibration, tool-free, adjustment slider under label windowSterilisationFully autoclavable at 121 °C, 2 bar, at least 15 minutes to DIN EN 285MarkingDE-MScope of delivery1x Transferpette S variable 10-100 µl (D-100)1x quality certificate1x silicone greaseIndividual requirements & procurement serviceIf the volume range does not match the complete requirement, it is worth looking at the neighbouring Transferpette S models or at the starter kits with several volume ranges in one set.

Eppendorf Xplorer Multichannel Pipette, 8-channel, 50–1,200 µL, green, 4861000163
The Eppendorf Xplorer 8-channel multichannel pipette can fill an entire column of a 96-well microplate in a single operation. The fixed 9 mm grid corresponds to the spacing of standard 8-well PCR strips, meaning that samples can also be transferred directly from such strips. Dosing is possible within the 50–1,200 µL range. Within this 50–1,200 µL range, the model is primarily designed for larger volumes, such as when transferring medium in cell culture.Calibration and cleaningThe pipette can be calibrated to the actual liquid being used via 1-, 2- or 3-point calibration, with options including 50 per cent glycerine, 75 per cent ethanol, the geographical altitude of the location of use, or epT.I.P.S. long. For cleaning, the entire lower section is steam-autoclavable at 121 °C for 20 minutes at 1 bar overpressure.The cone spacing on this model is fixed at 9 mm and is compatible with the respective microplate grid (9 mm for 96-well, 4.5 mm for 384-well formats). Those who regularly switch between tubes and plates will find the right model in the Xplorer plus Move It range.The epT.I.P.S. 50–1,250 µL green tip, 76 mm, is used to match the volume range and number of channels. Across all 8 channels, the standardised tip type ensures consistent aspiration and dispensing without dripping.The device is ordered under the manufacturer’s item no. 4861000163, which uniquely identifies both the green colour code and the volume range of 50–1,200 µL.The control interface consists of a rotary selector, a rocker switch and the soft-key display. As all 8 channels are controlled via the same cycle, the effort required per plate remains the same regardless of how many wells are ultimately filled.The model is colour-coded green, which makes it easier to match it with the correct pipette tip in the workplace, particularly when multiple channel counts and volume ranges are in use simultaneously.Within the Xplorer range, the basic Xplorer model is, according to the ordering information, available exclusively as 8- and 12-channel variants with a fixed 9 mm cone spacing. Those requiring 16 or 24 channels, an adjustable cone spacing or the Move-It function for switching between tubes and plates will find these features in the extended Xplorer-plus range, which utilises the same adjustment and battery technology.In day-to-day laboratory work, this 8-channel pipette with a 1 µL increment handles tasks that would otherwise require many individual steps: sample preparation for PCR, dilution series in assay development or the batch filling of test kits. Electronic operation via a rocker switch and display reduces the number of manual steps per plate.For mobile use across multiple workstations, the mains adaptor is rated for 100–240 V at 50/60 Hz, meaning there is no need to change adaptors, even within an international laboratory network. The replaceable lithium-polymer battery weighs around 20 g and, if required, can be swapped for a charged spare battery whilst the device is in operation, without having to connect it to the mains adaptor.At the workstation, the Xplorer pipette can be kept within easy reach in a pipette carousel or on a charging tray. As the operating logic and calibration procedures are standardised across the Xplorer range, no retraining is required when switching between different channel counts and volume ranges, not even when switching to or from this 8-channel model with 1 µL increments.Battery operationThe Xplorer’s lithium-polymer battery (750 mAh, 3.7 V) is sufficient for approximately 1,400 dispensing cycles and is fully recharged after around 3 hours when connected to the mains adapter. Dispensing is controlled via a selector dial and rocker switch, whilst the soft-key display guides the user through volume and operating mode selections.Typical applicationsThis is what it looks like in everyday use when 8 channels need to be filled simultaneously:filling and emptying entire 96-well microplates column by columndirect sample transfer from 8-well PCR strips into the plate, as both are in the same 9 mm gridserial dilution series across a single plate columnMedium changes in cell culture and transferring larger volumes between storage bottles and culture platesError limits in accordance with DIN EN ISO 8655-6The error limits are based on DIN EN ISO 8655-6:2002-12: 10 determinations per test volume, water in accordance with ISO 3696:1991-06, 20–25 °C, dispensing against the vessel wall, PIP operating mode, speed level 5. The table lists four test points ranging from 50 to 1200 µL. In practice, this means that anyone working close to the lower volume limit of 50 µL should factor in the slightly higher relative deviation of 8 per cent at that point, whilst the range around 1200 µL is significantly tighter at 1.2 per cent.Test volumeSystematic deviationRandom deviation50 µL8% / 4 µL1.2% / 0.6 µL120 µL6.0% / 7.2 µL0.9% / 1.08 µL600 µL2.7% / 16.2 µL0.4% / 2.4 µL1200 µL1.2% / 14.4 µL0.3% / 3.6 µLTechnical detailsNumber of channels8Volume range50–1,200 µLIncrement1 µLColour codegreenCone spacing9 mm (fixed)Pipette tipepT.I.P.S. 50–1250 µL green, 76 mmAutoclavability of base121 °C, 20 min, 1 bar overpressure (steam autoclavable)Calibration1-/2-/3-point calibration, including 50% glycerine, 75% ethanol and geographical altitude, epT.I.P.S. longOperationSelection dial, rocker switch, display with soft keysBatteryLithium-polymer, 750 mAh, 3.7 V, charging time approx. 3 hours, approx. 1,400 doses per charge, weight approx. 20 gMains adapter100–240 V ±10 per cent, 50/60 Hz, 5 V/1 ATest standard error limitsDIN EN ISO 8655-6:2002-12, 10 determinations per test volume, water in accordance with ISO 3696:1991-06, 20–25 °CContentsEppendorf Xplorer multichannel pipette, 8-channel, 50–1,200 µL, MPN 4861000163Rechargeable battery (pre-installed)Mains adaptorUser manualPipette tips and charging stations/pipette carousels are not included and are available separately.Individual requirements & procurement serviceLT Laborhandel’s procurement service is available to assist with suitable accessories such as epT.I.P.S. tips, charging stations or a pipette carousel, as well as spare parts and bespoke adjustment and calibration requirements.

Eppendorf Reference 2 single-channel pipette, variable, 100–1000 µL, blue, 4924000088
When changing the culture medium for a standard culture, a volume of between 100 and 1000 µL is usually required, depending on the vessel size and cell count; a variable-volume pipette covers this range with a single device. As a mechanical piston-driven pipette, it operates without a battery and without any charging time.Ergonomics and operationA spring-loaded tip cone ensures that the tip can be attached with minimal effort, whilst maintaining a consistent seal regardless of the user. If pipetting is regularly carried out with a liquid other than water, this can be compensated for via a secondary adjustment without overwriting the factory calibration. The set volume can be read from the four-digit display with magnifying window from virtually any position, whilst a lock prevents accidental adjustment. As culture vessels of different sizes require different volumes of medium, a single variable-volume pipette can replace several fixed-volume models for the respective vessel sizes. Tip ejection is controlled by the same operating button as tip loading and dispensing; there is no need to touch the used tip with your hand.Precision in accordance with ISO 8655Measurement deviations have been tested in accordance with ISO 8655 Part 6, using test volumes of 100 / 500 / 1000 µL. The systematic measurement deviation is as follows: 100 µL: 3.0%/3.0 µL; 500 µL: 1.0%/5.0 µL; 1000 µL: 0.6 per cent/6.0 µL, whilst the random measurement error is 100 µL: 0.6 per cent/0.6 µL; 500 µL: 0.2 per cent/1.0 µL; 1000 µL: 0.2 per cent/2.0 µL. These values can be used directly as the basis for your own quality documentation. The epT.I.P.S. blue 71 mm tip (50–1000 µL) is designed for use with this product.Autoclavability and material compatibilityThe pipette can be autoclaved for 20 minutes at 121 degrees Celsius and 1 bar overpressure without first separating the upper and lower sections. There is no need to re-lubricate the pistons, although a subsequent gravimetric check is still advisable. This means that, if contamination is suspected, the pipette can be sterilised directly whilst assembled, without first dismantling the lower section.Distinctions within the Eppendorf pipette familyWithin the Eppendorf pipette families, the Reference 2 differs from the Research plus in its single-button operation: the Research plus features a two-stage operation, but is the lightest model in the family requiring the least operating force. The electronic Xplorer range goes one step further, using a motor to control aspiration and dispensing speeds, including additional functions such as dilution or sequential pipetting. For those seeking a purely mechanical yet ergonomic solution with secondary adjustment, the Reference 2 sits between these two ranges.PhysioCare ConceptReduced weight and low operating force are the two key factors that the PhysioCare Concept focuses on in the Reference 2. Over the course of a long pipetting session, this results in less fatigue.Maintenance and CalibrationRegular calibration and a visual inspection of the moving parts ensure that the pipette remains within the specified measurement tolerances throughout its entire service life. Wear parts can be replaced individually; there is no need to replace the entire unit. In practice, this pipette is found in research laboratories, in quality assurance and in routine diagnostics – in other words, wherever pipetting results must be traceable and reproducible.Tip compatibility and colour codingAs the epT.I.P.S. tips are colour-coded to correspond to their respective volume ranges, it is possible to check at a glance on the pipette stand whether the attached tip is compatible with the pipette selected. When attaching the epT.I.P.S. blue 71 mm tip (50–1000 µL), the spring-loaded cone ensures a tight fit without the need for additional force. This means it is immediately clear from the pipette stand which tip box belongs to this pipette.Typical applicationsMedium changes between 100 and 1000 µL for standard cell culturesPipetting variable volumes in the range of 100 to 1000 microlitresAddition of reagents in routine analysis with varying requirementsTechnical detailsVolume range (variable)100–1,000 µLIncrement1 µLColour codeblueTest volume (ISO 8655)100 / 500 / 1000 µLSystematic measurement error100 µL: 3.0%/3.0 µL; 500 µL: 1.0%/5.0 µL; 1000 µL: 0.6%/6.0 µLRandom measurement error100 µL: 0.6%/0.6 µL; 500 µL: 0.2%/1.0 µL; 1000 µL: 0.2%/2.0 µLCompatible pipette tipepT.I.P.S. blue 71 mm (50–1000 µL)Autoclavability121 °C, 1 bar gauge pressure, 20 minutes (upper and lower parts assembled)StandardISO 8655, Part 6 (Test methods), Parts 2/5 (Test load)Contents1 x Eppendorf Reference 2 single-channel pipette, 100–1000 µL, blue, 4924000088epT.I.P.S. box with matching pipette tipsUser manualCustomised requirements & procurement serviceIf additional accessories are required – such as matching epT.I.P.S. tips in larger quantities, spare parts or an external calibration – LT Laborhandel will handle the procurement.

Eppendorf Reference 2 Multichannel Pipette, 8-channel, 0.5–10 µL, medium grey, 4926000018
The Eppendorf Reference 2 multichannel pipette, 8-channel, 0.5–10 µL, medium grey, is designed for high-repetition pipetting in day-to-day laboratory work. With 8 channels, it is designed for column-by-column operation: an entire column of a microtitre plate or an 8-well PCR strip can be transferred in a single stroke, for example when transferring PCR products to a detection plate or when loading a strip format. The volume range of 0.5–10 µL covers typical PCR and qPCR set-ups, where master mix, primers or probes are dispensed in very small quantities across many wells, often in the single-digit microlitre range. Instead of a conventional rotary dial, the instrument features a single-button control: once the target volume has been set in the morning and the same value is used to pipette series after series throughout the day, there is no need for readjustment; a glance at the display before each new series is sufficient. The epT.I.P.S. 0.1–20 µL medium grey, 40 mm tips are designed for this purpose; the order number for this version is 4926000018. The medium grey colour code on the 8 tip cones corresponds to the volume colour coding used by Eppendorf for this range and makes it easier to identify the correct epT.I.P.S. tips in the tip rack.Typical applicationsThe Reference 2 multichannel pipette, 8-channel, 0.5–10 µL, is primarily used in everyday laboratory work for the following steps, where the same volume needs to be dispensed repeatedly into several wells:Simultaneous dispensing of PCR and qPCR master mixes into multiple wellsTransfer of entire PCR strips or plate columns in a single strokeLoading plates with primers or probes in the single-microlitre rangeDilution series for molecular biology using very small volumesWorkstations where the medium-grey colour-coding of the 8-channel tips is used for quick identification in the tip rackSelection guideIf you are looking for the same volume range of 0.5–10 µL with a classic, mechanical piston-driven pipette rather than a single-button operation, the Eppendorf Research plus offers an alternative in the range. For column-by-column work or row-by-row filling with a different number of channels, the 12-channel version of the Reference 2 with the same volume range is also available. If you have any queries regarding the appropriate number of channels or the suitable volume range for your own workflow, LT Laborhandel’s procurement service will be happy to assist. For programming functions, multiple dispensing modes or battery operation, LT Laborhandel also stocks the electronic Eppendorf Xplorer/Xplorer plus series, an alternative to the mechanical pipette described here. The 8-channel version with a volume range of 0.5–10 µL can be exchanged at any time for a different number of channels or a different volume range within the same series, without altering the rest of the laboratory workflow.Accuracy in accordance with DIN EN ISO 8655Testing is carried out in accordance with DIN EN ISO 8655, with ten repetitions per test point and water in accordance with ISO 3696, with dispensing against the vessel wall. For the 0.5–10 µL range, the values at the test points lie between 0.5 and 10 µL; these are broken down below into systematic and random deviations.Recommended pipetting technique and environmental conditionsTips that are not seated evenly are one of the most common causes of deviations between individual channels of a multichannel pipette; a quick visual check before the series helps to prevent this. The permissible operating range is 5 to 40 °C and 10 to 95 per cent relative humidity; for storage without packaging, the range is –5 to 45 °C. With 8 channels in use simultaneously, it is worth carrying out a brief test pipette stroke with water before the first run of the day to check that all channels are aspirating evenly before pipetting the actual samples.Technical detailsNumber of channels8Volume range0.5–10 µLColour codemedium greyCone spacingfixed, 9 mmCompatible tipepT.I.P.S. 0.1–20 µL medium grey, 40 mmTest standard tolerance limitsDIN EN ISO 8655Tolerance limits according to DIN EN ISO 8655Test volumeSystematic deviationRandom deviation (VK)0.5 µL12.0% / 0.06 µL8.0% / 0.04 µL1 µL8.0% / 0.08 µL5.0% / 0.05 µL5 µL4.0% / 0.2 µL2.0% / 0.1 µL10 µL2.0% / 0.2 µL1.0% / 0.1 µLContents1x Eppendorf Reference 2 multichannel pipette, 8-channel, 0.5–10 µL, medium grey, 4926000018Customised requirements & procurement serviceThe Eppendorf Pipette Carousel 2 from the LT range is suitable for storing several pipettes at the same workstation; it holds up to six mechanical dispensing devices and, according to the manufacturer, is compatible with this series.

Eppendorf Research plus single-channel pipette, variable, 1–10 mL, turquoise, 3123000080
Varying sample volumes within the same volume range require a pipette that can be adjusted quickly and without the need for tools. The Eppendorf Research plus single-channel pipette, in its variable 1–10 mL turquoise version, meets precisely this need, with 0.01 mL increments and a spring-loaded tip cone that reduces the effort required to attach tips. It is designed for workstations where dilution series or different sample volumes are used in the same batch.Typical applicationsThe Eppendorf Research plus 1–10 mL is suitable, amongst other things, for:Preparing larger volumes of buffers and mediaDilution of stock solutionsFilling test tubes and culture flasksDecanting during sample preparation in routine laboratoriesFeatures and handlingFor volumes up to 1 mL, Eppendorf’s Research-plus range features a spring-loaded tip cone, which makes attaching and ejecting the pipette tip noticeably easier. The low weight of the Research-plus range is particularly noticeable in terms of ease of use during extensive pipetting runs. The lower section, featuring a Fortron PerfectPiston, can be quickly dismantled without tools for maintenance and cleaning.Eppendorf provides a user adjustment feature for the Research-plus range, known as secondary adjustment, which allows the pipette to be set for a liquid other than water without permanently altering the factory setting.Selection guide within the Research-plus rangeThe volume ranges vary significantly across the variable Research-plus models. The following overview shows neighbouring variable models from the same range:VolumeColour codeMPN2–20 µLlight grey31230000982–20 µLyellow312300003930–300 µLorange3123000101100–1000 µLblue3123000063The appropriate volume in each individual case depends on the actual sample quantities and reagent volumes involved in the respective step. Selecting a volume that is too large reduces relative accuracy at the lower end of the scale, whilst selecting a volume that is too small necessitates several pipetting steps instead of a single one.Comparing Research plus, Reference 2 and XplorerAnyone choosing between the three Eppendorf manual pipette ranges should first consider the operation. The Research plus is adjusted via a mechanical adjustment wheel, with no electronics and no display, making it robust and low-maintenance. The Reference 2 replaces the adjustment wheel with a single-button operation featuring a digital display, which is practical for laboratories with frequently changing volumes and multiple users sharing the same instrument. The Xplorer and Xplorer Plus go one step further, pipetting electronically programmed sequences, including password protection on the Plus model. For a clearly defined volume range in routine work, the mechanical Research Plus range remains the simplest choice.Differentiation within the Research plus rangeIf the volume range of this pipette does not fully meet your requirements, it is worth looking at neighbouring Research plus models, for example the Eppendorf Pipette Research plus G, single-channel, variable, 2–20 µL, light grey, epT.I.P.S. box, 3123000098 Eppendorf Pipette Research plus G, single-channel, variable, 2–20 µL, yellow, epT.I.P.S. box, 3123000039. This allows you to put together a suitable combination of several volume ranges without having to switch to a different product line.Use, storage and maintenanceThe upper and lower sections can be autoclaved together at 121 °C and 1 bar overpressure for 20 minutes; it is not necessary to dismantle the lower section for this. The filter sleeve and protective filter are autoclaved separately. No re-lubrication is required after autoclaving; a gravimetric accuracy check is recommended afterwards. The pipette is stored without transport packaging at temperatures between –5 and 45 degrees Celsius and relative humidity of 10 to 95 per cent; during operation, the temperature range is 5 to 40 degrees Celsius within the same humidity range. Warranty claims are handled via the relevant Eppendorf authorised partner; claims are excluded for damage resulting from misuse, unauthorised opening of the upper section, and wear and tear on typical wear parts.Fixed volume or variable settingAnyone who switches between several volumes within the same range in their day-to-day work – for example, when carrying out dilution series or handling different sample volumes per batch – will find a variable-volume pipette more flexible than using several fixed-volume devices. For a single, recurring value, however, a fixed-volume pipette from the Research-plus range is the better choice, as it prevents the adjustment wheel from being turned in the first place.Frequently asked questionsIs the Eppendorf Research plus 1–10 mL autoclavable?Yes. The upper and lower sections can be autoclaved together at 121 degrees Celsius and 1 bar overpressure for 20 minutes without the lower section needing to be dismantled.

Eppendorf Research plus Move It multi-channel pipette, 6-channel, 120–1200 µL, adjustable cone spacing, dark green, 3125000192
The Eppendorf Research plus Move It multi-channel pipette, 6-channel, 120–1200 µL, dark green, adds an adjustable cone spacing to the Research plus range. Six channels with an adjustment range of 9–20 mm cover a mid-range between the 4- and 8-channel Move It variants, for protocols involving mixed well spacing. The 120–1200 µL volume range is designed for medium changes in cell culture and larger volumes of reagents, such as when transferring culture medium to several wells of a deep-well or culture plate simultaneously. The cone spacing is adjusted via a rotary knob with a scale on the multichannel base, so that the same pipette can be used for both the dense 9 mm grid of a well plate and for vessels spaced further apart, without having to change the device. The recommended tip for this is the epT.I.P.S. 50–1200 µL dark green, 103 mm tip; the order number for this version is 3125000192. The dark green colour code on the 6 tip cones corresponds to the volume colour coding used by Eppendorf for this range and makes it easier to identify the correct epT.I.P.S. tips in the tip rack.Typical applicationsThe Research plus Move It multichannel pipette, 6-channel, 120–1200 µL, is primarily used in day-to-day laboratory work for the following tasks, where the same volume needs to be dispensed repeatedly into several wells:Changing the culture medium in cell culture across several wells simultaneouslyTransferring between well plates and vessels of medium heightTransferring larger volumes of reagents into deep-well platesPreparing stock solutions and dilutions in the millilitre rangeWorkstations where the dark green colour-coding of the 6-channel tips is used for quick identification in the tip rackSelection guideIf you work exclusively with a fixed grid spacing, the standard version of the Research plus without the Move-It mechanism will suffice; it is slightly cheaper. The Move-It variant is worthwhile as soon as the same workflow involves handling both well plates and vessels with wider or narrower spacing, without the need to purchase a second device. If you have any queries regarding the appropriate number of channels or the suitable volume range for your own workflow, LT Laborhandel’s procurement service will be happy to assist. For programming functions, multiple dispensing modes or battery operation, LT Laborhandel also stocks the electronic Eppendorf Xplorer/Xplorer plus series, an alternative to the mechanical pipette described here. Should the laboratory’s requirements change, this 6-channel model (120–1200 µL) can be supplemented at any time with a second channel count or a second volume range from the same series.Accuracy in accordance with DIN EN ISO 8655Testing is carried out in accordance with DIN EN ISO 8655, with ten repetitions per test point and water in accordance with ISO 3696, with dispensing against the vessel wall. For the 120–1,200 µL range, the values at the test points are between 50 and 1,200 µL, broken down below into systematic and random deviations.Recommended pipetting technique and environmental conditionsTips that are not seated evenly are one of the most common causes of deviations between individual channels of a multichannel pipette; a quick visual check before the series helps to prevent this. The permissible operating range is 5 to 40 °C and 10 to 95 per cent relative humidity; for storage without packaging, the range is –5 to 45 °C. With 6 channels in use simultaneously, it is worth carrying out a brief test pipette stroke with water before the first run of the day to check that all channels are aspirating evenly, before pipetting the actual samples.Technical detailsNumber of channels6Volume range120–1200 µLSmallest increment1 µLColour codedark greenCone spacing, adjustable9–20 mmCompatible tipepT.I.P.S. 50–1200 µL dark green, 103 mmTest standard error limitsDIN EN ISO 8655Tolerance limits according to DIN EN ISO 8655Test volumeSystematic deviationRandom deviation (VK)50 µL14.5% / 7.25 µL2% / 1 µL120 µL6% / 7.2 µL1.3% / 1.6 µL600 µL2.7% / 16.2 µL0.4% / 2.4 µL1200 µL1.2% / 14.4 µL0.3% / 3.6 µLContents1x Eppendorf Research plus Move It multichannel pipette, 6-channel, 120–1200 µL, dark green, 3125000192Customised requirements & procurement serviceMatching epT.I.P.S. tips (epT.I.P.S. 50–1200 µL dark green, 103 mm) are not included in the scope of delivery and are available separately.

Eppendorf Pipette Carousel 2, holder for 6 pipettes, 3116000015
If you want to have several pipettes to hand at the same time on a bench, you don’t need a stand for each device. The Pipette Carousel 2 holds up to six pipettes at once and can be rotated freely by its carrying handle, so that every pipette is accessible without having to change your grip. Six positions, one pivot point The carousel holds six dispensing devices, whether single-channel pipettes, multi-channel pipettes or dispensers. The pipette holders are reversible and interchangeable, so the configuration can be adapted to different device sizes without having to replace the entire carousel. Compatible with standard mechanical series According to the user manual, the carousel accommodates the following mechanical dispensing devices: Multipette/Repeater M4, Reference 2, Reference, Biomaster, Research plus, Research and Research 3. Electronic charging cradles can also be used, although the charging contacts on the carousel itself do not function in this case: an electronic device such as the Multipette E3 or E3x continues to charge only via its own mains adaptor. Stable and robust in everyday use Rubber feet ensure stability, even when several pipettes are inserted or removed at the same time. The base plate is made of 1.4301 stainless steel; the carrying handle, pipette holders and outer surfaces are made of ASA/PC (acrylonitrile-styrene-acrylate copolymer with polycarbonate). The carousel itself is not autoclavable and does not have its own charging function. Typical applications Central storage for several single-channel or multi-channel pipettes at a single workstation Joint storage of mechanical dispensers and pipettes in the same carousel Workstations where equipment is changed frequently and where quick access without searching is essential Training and educational laboratories where several types of pipettes are in use Technical details Capacity6 dispensing devices (single-channel pipettes, multi-channel pipettes or dispensers) Compatible mechanical dispensing devicesMultipette/Repeater M4, Reference 2, Reference, Biomaster, Research plus, Research, Research 3 Electronic devicesCharging cradles can be used; charging contacts on the carousel are non-functional; charging continues via the device’s own power supply DesignRotating carousel with carrying handle, reversible and interchangeable pipette holders Material (carrying handle/pipette holders/external surfaces)ASA/PC (acrylonitrile-styrene-acrylate copolymer with polycarbonate) Material of base plateStainless steel 1.4301 Material of feetSilicone AutoclavabilityNot autoclavable Contents Pipette carousel 2 with six reversible, interchangeable pipette holders Pipettes and dispensers are not included in the scope of delivery.

Eppendorf Multipette E3x Hand-operated Dispenser with Charging Stand, Electronic, 4987000380
This version of the Multipette E3x also comes with a charging stand. Users who regularly place the dispenser on the stand and remove it again do not need to connect the unit to the mains cable each time; instead, they simply place it on the stand, and it charges automatically via the contacts. Basic modes plus advanced applications Like the E3x without the charging stand, this variant also operates using a motorised direct displacement principle. Dispensing (Dis), automatic dispensing (Ads) and pipetting (Pip) cover the basic functions. According to Eppendorf’s manufacturer’s specifications, the E3x offers additional operating modes, including titration, sequential dispensing and aspiration/dispensing. Loading rack for a fixed workstation At a fixed workstation, the charging stand reduces the number of steps required between two operations. According to the manufacturer’s specifications, the 1,200 mAh lithium-ion battery lasts for around five hours under test conditions, with at least 500 aspirations and 10,000 dispensing steps, and is fully recharged in around two hours. High resolution across the entire Combitip range With 5,000 possible dispensing volumes and increments from 100 nL for the smallest Combitip size, the E3x covers the entire range from 1 µL to 50 mL in fine increments. Selection guide: M4, E3 or E3x If you need a Multipette without ever having to worry about a battery, the M4 is the right choice for you. It requires no charging cycles; according to the manufacturer, a single button cell lasts around two years and powers only the automatic volume detection. If, in addition to the three basic modes, dispensing, automatic dispensing and pipetting, you also need titrations, sequential dispensing steps or aspiration/dispensing in a single operation, the E3x is the right choice: According to Eppendorf’s specifications, it offers additional operating modes for these advanced applications, whilst the E3 sticks to the three basic modes. Those who do not require these additional functions will find the more affordable E3 sufficient, as it offers the same dispensing technology without the advanced modes. Product range overview: Multipette, Research plus and Xplorer A Multipette is a repeat dispenser: it draws a larger volume of liquid from the Combitip advanced using a single aspiration and then dispenses it in several equal portions without having to aspirate again in between. This is worthwhile whenever the same volume needs to be dispensed repeatedly into many vessels, such as when filling a microtitre plate. A Research plus or Xplorer pipette, on the other hand, is a piston-stroke pipette based on the air-cushion principle: It draws up a single volume at a time using an epT.I.P.S. tip and dispenses it once before drawing up again; this is the right choice for single volumes or small series with varying quantities. Because, with the Multipette’s direct displacement principle, the liquid flows exclusively through the Combitip and does not come into contact with the device, the Multipette is also suitable for viscous, foaming or volatile media, where an air cushion in the pipette tip would lead to inaccuracies. For viscous samples, the M4 also offers a ViscoTip with a 10 mL volume. Typical applications Titration and stepwise dispensing with monitoring of the reaction after each step Sequential dispensing of different partial volumes in a single operation Continuous dispensing of the same volume for dilution series and plate filling, particularly at fixed workstations where the instrument is frequently placed down and picked up Reagent addition in diagnostics, quality control and research with higher demands on process versatility Use and maintenance When a new Combitip advanced is fitted, the Multipette automatically recognises the tip size used and sets the appropriate volume range. The desired operating mode can be selected directly on the device via the display, without the need for external software. After use, the Combitip is disposed of together with its integrated piston; the device itself does not come into contact with the dispensed liquid. The battery is charged via the supplied mains adaptor with a micro-USB interface; according to the manufacturer’s specifications under test conditions, a full charge is sufficient for at least 500 aspirations and 10,000 dispensing cycles. We can provide information on the autoclavability of the dispenser housing itself on request; only the Combitips advanced, as disposable items, are affected by sterilisability requirements. Technical details Dispensing principleDirect displacement via Combitips advanced, motorised Total volume range1 µL to 50 mL, depending on the Combitip advanced used Dispensing volumes5,000 different volumes, in increments from 100 nL for the smallest Combitip size Example increment, smallest tipCombitip 0.1 mL: 1 to 100 µL, increment 1 µL Example increment, largest tipCombitip 50 mL: 0.5 to 50 mL, increment 0.5 mL Operating modes: Basic functionsDispensing (Dis), automatic dispensing (Ads), pipetting (Pip) Additional operating modes (according to Eppendorf manufacturer’s specifications)including titration, sequential dispensing, aspiration/dispensing Dispenser weightapprox. 190 g InterfaceMicro-USB BatteryLithium-ion, 3.7 V, 1200 mAh, weight approx. 26 g, charging time approx. 2 hours Battery lifeapprox. 5 hours under test conditions (at least 500 readings, 10,000 dispensing steps) Mains adaptorInput 100 to 240 V, 50/60 Hz, 0.25 A, output 5 V/1 A/5 W Test standard error limitsISO 8655 Part 6, speed class 5, officially calibrated precision balance, 10 determinations per volume Operating environmental conditions5 to 40 °C, 10 to 95 per cent relative humidity, non-condensing, 795 to 1060 hPa Scope of delivery Multipette E3x hand-held dispenser Charging adapter (mains power supply, 100 to 240 V/50 to 60 Hz) Charging stand 1 Combitips advanced assortment pack Regulatory information As a battery-powered, motorised dispensing device with a mains power supply, this product is subject to WEEE registration requirements. We will provide the WEEE registration number on request. Frequently asked questions Do I need to reset the volume when changing the Combitip size? No, the device automatically recognises the tip size. What can the E3x do that the E3 cannot? According to Eppendorf’s manufacturer’s specifications, in addition to the three basic modes, dispensing, automatic dispensing and pipetting, the E3x offers further operating modes, including titration, sequential dispensing and aspiration/dispensing. What is the titration mode suitable for? According to the manufacturer’s specifications, it is suitable for applications where the sample is dispensed in incremental steps and the reaction is monitored after each step, rather than dispensing a fixed volume in one go. How long does the battery last in everyday use? According to the manufacturer’s specifications, under test conditions it lasts around 5 hours for at least 500 aspirations and 10,000 dispensing steps; it takes approximately 2 hours to charge. Is the E3x suitable for foaming or volatile media? As the liquid flows exclusively through the Combitip when using the direct displacement principle, the risk of inaccuracies caused by air pockets is lower than with piston-action pipettes.

Eppendorf Research plus single-channel pipette, variable, 0.5–5 mL, purple, 3123000071
Varying sample volumes within the same volume range require a pipette that can be adjusted quickly and without the need for tools. The Eppendorf Research plus single-channel pipette, in its variable 0.5–5 mL version in purple, meets precisely this need, with an increment of 0.005 mL and a spring-loaded tip cone that reduces the effort required to attach tips. It is designed for workstations where dilution series or different sample volumes occur within the same batch.Typical applicationsThe Eppendorf Research plus 0.5–5 mL is suitable, amongst other things, for:Preparing larger volumes of buffers and mediaDilution of stock solutionsFilling test tubes and culture flasksDecanting during sample preparation in routine laboratoriesFeatures and handlingThe spring-loaded tip cone, which Eppendorf uses in all Research plus pipettes up to 1 mL, reduces the force required to attach and eject the pipette tip. Within the Eppendorf pipette range, Research plus is one of the lightest models, which is an advantage when carrying out many consecutive pipetting steps. The Fortron PerfectPiston is housed in a base section that can be dismantled without tools, which is practical for cleaning and maintenance.If the pipetting result deviates from the expected accuracy – for example, when using a liquid other than water – the pipette can be readjusted via a user adjustment without losing the original factory setting.Selection guide within the Research-plus rangeThe volume ranges vary significantly across the variable Research-plus models. The following overview shows comparable variable models from the same range:VolumeColour codeMPN1–10 mLturquoise31230000802–20 µLlight grey31230000982–20 µLyellow312300003930–300 µLorange3123000101The appropriate volume in each individual case depends on the actual sample quantities and reagent volumes involved in the respective step. Selecting a volume that is too large reduces relative accuracy at the lower end of the scale, whilst selecting a volume that is too small necessitates several pipetting steps instead of a single one.Comparison of Research plus, Reference 2 and XplorerThree product lines, three operating concepts: Research plus operates purely mechanically via a control wheel, without electricity or a display. Reference 2 displays the set volume digitally and is operated via a single button, which reduces the effort required. Xplorer and Xplorer plus pipette electronically, with adjustable dispensing speeds and, in the Plus version, additional programmes such as sequential pipetting. Research plus remains the range with the lowest weight and the simplest handling when no display or programming is required.Differentiation within the Research plus rangeIf the volume range of this pipette does not fully meet your requirements, it is worth looking at similar Research plus models, for example the Eppendorf Research plus single-channel pipette, variable (1–10 mL), 3123000080 Eppendorf Research plus G pipette, single-channel, variable, 2–20 µL, light grey, epT.I.P.S. box, 3123000098. This allows you to put together a suitable combination of several volume ranges without having to switch to a different product line.Use, storage and maintenanceAutoclaving is possible whilst the pipette is fully assembled, at 121 °C and 1 bar overpressure for 20 minutes; the lower section remains attached during this process. The filter sleeve and protective filter are autoclaved separately. There is no need to re-lubricate after autoclaving; a gravimetric check afterwards is recommended. Without transport packaging, the pipette should be stored at between –5 and 45 degrees Celsius and 10 to 95 per cent relative humidity; during operation, it should be kept at between 5 and 40 degrees Celsius within the same humidity range. The relevant Eppendorf authorised partner is responsible for warranty matters, with the exception of wear parts and damage resulting from misuse or unauthorised opening of the upper part.Fixed volume or variable settingA variable-volume pipette is worthwhile whenever different volumes within the same range are required during a workflow, such as for dilution series or varying sample volumes. The adjustment wheel allows for adjustment without tools and without changing equipment. If, on the other hand, only a single volume is pipetted on a permanent basis, a fixed-volume pipette from the same range reduces the risk of error caused by accidental adjustment.Frequently asked questionsIs the Eppendorf Research plus 0.5–5 mL autoclavable?Yes. The upper and lower sections can be autoclaved together at 121 degrees Celsius and 1 bar overpressure for 20 minutes without the lower section needing to be dismantled. The filter sleeve and protective filter are autoclaved separately.How is accuracy checked after autoclaving?Re-lubrication is not necessary; however, Eppendorf still recommends a gravimetric check after autoclaving to confirm accuracy.How is the volume set on the variable model?Via the mechanical adjustment wheel on the pipette head, without a display or electronics.

Eppendorf Research plus single-channel pipette, variable, 2–20 µL, yellow, 3123000039
Varying sample volumes within the same volume range require a pipette that can be adjusted quickly and without the need for tools. The Eppendorf Research plus single-channel pipette, in its variable 2–20 µL version (yellow), meets precisely this need, with 0.02 µL increments and a spring-loaded tip cone that reduces the force required for tip loading. It is designed for workstations where dilution series or different sample volumes are used within the same batch.Typical applicationsThe Eppendorf Research plus 2–20 µL is suitable for, amongst other things:PCR reactions and dilution seriesReagent addition in ELISA diagnosticsSample preparation for sequencingPipetting small volumes into microtitre platesFeatures and handlingA spring-loaded tip cone on all Research plus models up to 1 mL ensures that pipette tips can be attached and ejected with minimal effort. Within the Eppendorf pipette range, the Research plus is one of the lightest models, which is an advantage when carrying out many consecutive pipetting steps. The lower section, featuring a Fortron PerfectPiston, can be quickly dismantled without tools for maintenance and cleaning.For secondary calibration – i.e. calibration for a liquid other than water or to a custom factory setting – the manufacturer states that Research-plus pipettes feature a user calibration function that does not overwrite the original factory setting.Selection guide within the Research-plus rangeThe volume ranges vary significantly across the variable Research-plus models. The following overview shows neighbouring variable models from the same range:VolumeColour codeMPN1–10 mLturquoise31230000802–20 µLlight grey312300009830–300 µLorange3123000101100–1000 µLblue3123000063The appropriate volume in each individual case depends on the actual sample quantities and reagent volumes involved in the respective step. Selecting a volume that is too large reduces relative accuracy at the lower end of the scale, whilst selecting a volume that is too small necessitates several pipetting steps instead of a single one.Comparison of Research plus, Reference 2 and XplorerWhen choosing between Research plus, Reference 2 and Xplorer, the frequency of volume changes is the key deciding factor. Research plus adjusts the volume mechanically via a dial, without a display, which makes the pipette lightweight and robust. Reference 2 displays the volume digitally and can be operated using a single button, which is an advantage where there are multiple users and varying protocols. Xplorer and Xplorer plus handle pipetting electronically, including programmable sequences. For workstations with a clearly defined volume range and no need for programming functions, Research plus is the more streamlined solution.Differentiation within the Research plus rangeIf the volume range of this pipette does not fully meet your requirements, it is worth considering neighbouring Research plus models, for example the Eppendorf Research plus single-channel pipette, variable (1–10 mL), 3123000080 Eppendorf Research plus G pipette, single-channel, variable, 2–20 µL, light grey, epT.I.P.S. box, 3123000098.

Eppendorf Research plus single-channel pipette, fixed, 1000 µL, blue, 3124000121
Anyone who repeatedly pipettes the same volume does not need a variable setting, but rather a reliable preset that cannot be accidentally adjusted. The Eppendorf Research plus 1000 µL in blue is designed precisely for this purpose: a fixed volume of 1000 µL, a spring-loaded tip cone for effortless tip attachment, and a low weight within the Eppendorf pipette range. The pipette is suitable for routine procedures in which the same volume is dispensed over many repetitions. A classic example is medium change in cell culture, where the same volume of culture medium is removed from and added back to each culture vessel, day after day, following the same procedure.Typical applicationsThe Eppendorf Research plus 1000 µL is suitable for, amongst other things:Media changes in cell culture, where the same volume of culture medium is always removed or added to each culture vesselBuffer preparations and reagent dispensing in the medium-volume rangeSample aliquoting and sample preparationFilling reaction vessels and cuvettesFeatures and handlingFor volumes up to 1 mL, Eppendorf’s Research-plus range features a spring-loaded tip cone, which makes attaching and ejecting the pipette tip noticeably easier. The pipette is one of the lightest in the Eppendorf range, which makes a noticeable difference to user comfort during long pipetting runs. For cleaning and maintenance, the lower section with the Fortron PerfectPiston can be quickly dismantled without the need for tools.If the pipetting result deviates from the expected accuracy – for example, when using a liquid other than water – the pipette can be readjusted via a user adjustment without losing the original factory setting.Selection guide within the Research-plus rangeSeveral volumes are available within the pre-set Research-plus models.

Selecting a volume that is too large reduces relative accuracy at the lower end of the scale, whilst selecting a volume that is too small necessitates several pipetting steps instead of a single one.For medium changes, the blue tip range (50 to 1000 µL) is suitable; this range also includes the 200 µL, 250 µL and 500 µL fixed-volume versions, as well as the variable 100–1000 µL version from the same range.A comparison of Research plus, Reference 2 and XplorerWhen choosing between Research plus, Reference 2 and Xplorer, the frequency of volume changes is the key deciding factor. Research plus adjusts the volume mechanically via a dial, without a display, which makes the pipette lightweight and robust. Reference 2 displays the volume digitally and is operated via a single button, which is an advantage where there are multiple users and varying protocols. Xplorer and Xplorer plus handle pipetting electronically, including programmable sequences. For workstations with a clearly defined volume range and no need for programming functions, Research plus is the more streamlined solution.Differentiation within the Research plus rangeIf the volume range of this pipette does not fully meet your requirements, it is worth looking at neighbouring Research plus models, for example the Eppendorf Research plus G pipette, single-channel, fixed, 200 µL, blue, 3124000091 Eppendorf Research plus G pipette, single-channel, fixed, 50 µL, yellow, 3124000067. This allows you to put together a suitable combination of several volume ranges without having to switch to a different product line.Use, storage and maintenanceSterilisation in an autoclave is intended to be carried out at 121 °C, 1 bar overpressure and a holding time of 20 minutes whilst the pipette is fully assembled, without dismantling the lower section; the filter sleeve and protective filter are autoclaved separately. There is no need to re-lubricate the pistons afterwards, although a gravimetric check of accuracy is nevertheless advisable. For storage without transport packaging, the temperature range is –5 to 45 degrees Celsius at 10 to 95 per cent relative humidity; the unit is designed for operation at 5 to 40 degrees Celsius within the same range. The relevant Eppendorf authorised dealer is responsible for warranty matters, excluding wear parts and damage caused by misuse or an unauthorised opening of the upper part.Fixed volume or variable settingWhere a pipetting step is always carried out with the same volume – for example, with standardised test kits or recurring dilution steps – a fixed-volume pipette saves time compared with readjusting a variable pipette. At the same time, the risk of accidental adjustment during batch work is reduced. If the required volume varies from project to project, a variable Research-plus pipette from the same range is the more flexible alternative. During daily media changes in cell culture, the volume per culture vessel is specified by the protocol; a fixed preset speeds up batch processing and prevents the dial from being accidentally adjusted.Frequently Asked QuestionsIs the Eppendorf Research plus 1000 µL autoclavable?Yes. The upper and lower sections can be autoclaved together at 121 degrees Celsius and 1 bar overpressure for 20 minutes without the lower section needing to be dismantled. The filter sleeve and protective filter are autoclaved separately.Does the pipette need to be recalibrated after autoclaving?It is not necessary to re-lubricate the pistons after autoclaving. However, a gravimetric accuracy check is still recommended afterwards.Can the volume of the 1000 µL version be adjusted?No, this version has a fixed preset volume of 1000 µL and no volume selection dial. If you require different volumes within the same range, you will find suitable variable models in the Research plus range.Which pipette tips are compatible with the Eppendorf Research plus 1000 µL?According to the operating instructions: epT.I.P.S. blue 71 mm (50–1000 µL).Is the pipette an in vitro diagnostic device?According to the operating instructions, the Research-plus range is designed for the low-contamination transfer of liquids, including samples from the human body and reagents within the context of an in vitro diagnostic application as defined by Directive 98/79/EC.To whom should warranty claims be addressed?To the relevant Eppendorf authorised dealer. Excluded are damages resulting from misuse, unauthorised opening of the upper part, and wear and tear of typical wear parts.Can the pipette be readjusted if it deviates from the factory setting?According to the manufacturer, secondary calibration is provided for the Research-plus range. Details are set out in a separate Eppendorf calibration document, the full text of which was not available at the time of writing.What does the IVD marking on the Research-plus range signify?The user manual generically refers to the pipette as an in vitro diagnostic device within the meaning of Directive 98/79/EC, for the entire Research-plus range.

Brand Transferpette S -8 Multichannel Pipette, 8-Channel, 5-50 µl, DE-M, 705906
For many protocols, there is a range between master mix addition and assay volume that is neither very small nor yet large. The Transferpette S -8 in the 5-50 µl range closes this gap column by column across eight channels.Model M8-50 combines 8 individually manufactured and tested pistons in one housing and thus covers 5-50 µl at an increment of 0.05 µl. The matching tips in the 2-200 µl range can be removed without contact via the ejection mechanism. Because the piston guidance runs jointly across all 8 channels, the effort when pipetting hardly differs from a single-channel pipette.Adjustment without toolsThe adjustment slider sits under the label window and allows tool-free volume correction directly on the pipette body. In addition, a volume offset can be used to respond to deviating media or site conditions.Reprocessing in the autoclaveThe Transferpette S -8 is autoclavable as a complete device, 121 °C, 2 bar, holding time at least 15 minutes according to DIN EN 285, without any components having to be dismantled beforehand. On the electronic sister series, the Transferpette -8 electronic, only the unscrewable pipette shaft can be autoclaved, which is a significant difference between the mechanical and the electronic version.Ergonomics in series operationSo that 8 pistons can be guided in parallel without excessive effort, the pipette body of the Transferpette S -8 is designed for continuous use on the plate. The finger stroke remains even across the entire 5-50 µl range, and the span of the hand is not overtaxed. The number of channels is clearly legible on the housing, and the grip section and tip cone are kept neutral in colour.Place within the Transferpette S familyIn the same model system, the Transferpette S -12 with 12 channels is also available alongside the 8-channel version, and for individual samples the single-channel series Transferpette S Fix and Variable. The adjustment method and autoclavability are built the same way across the entire series, so switching between channel counts requires no new training.Selection guideFor smaller additions below 5 µl, the neighbouring variant with 0.5-10 µl (MPN 705900) is available, and for larger assay volumes the version with 10-100 µl (MPN 705908). Channel count, model and adjustment method stay identical when switching between volume steps of the same series, only the test range and the corresponding tip size change. If you are unsure which range suits your protocol, base the choice on the volume you pipette most often within the series and pick the range in which this volume lies as close as possible to the upper test point.Typical applicationsReagent addition column by column in microtitre platesBuffer changes between adjacent well columnsDilution series in the two-digit microlitre range in parallel across eight channelsAccuracy across the test rangeTesting is carried out at three test volumes (100 %, 50 % and 10 % of the nominal volume 5-50 µl). The systematic measurement error is given as 50 µl: ± 0.8 % / 25 µl: ± 1.4 % / 5 µl: ± 6 %, the random measurement error (coefficient of variation) as 50 µl: ± 0.4 % / 25 µl: ± 0.8 % / 5 µl: ± 3 %. As with any air displacement pipette, the relative deviation grows towards the lower test point and is tightest at the upper test point. In practical terms, dosing close to the upper end of the nominal volume is the most reproducible, while smaller partial volumes benefit from an additional check in critical dilution series.Technical detailsFeatureValueNumber of channels8Volume range5-50 µlIncrement0.05 µlModelM8-50Pipette tip2-200 µlSystematic measurement error (100/50/10 %)50 µl: ± 0.8 % / 25 µl: ± 1.4 % / 5 µl: ± 6 %Random measurement error CV (100/50/10 %)50 µl: ± 0.4 % / 25 µl: ± 0.8 % / 5 µl: ± 3 %Autoclavabilitycomplete, 121 °C, 2 bar, at least 15 min according to DIN EN 285AdjustmentEasy Calibration, adjustment slider under the label window, volume offsetManufacturer part no.

Brand Transferpette S Starter Kit Midi, 3 Pipettes 2 µl to 1000 µl, DE-M, 705891
Anyone who wants to equip a laboratory with several volume ranges in one go rarely needs just a single pipette. The Brand Transferpette S Starter Kit Midi bundles 3 variable single-channel pipettes from 2 µl to 1000 µl in one set and thus covers in one go what would otherwise require several individual orders, ready for use directly in the stand and typically suitable for general laboratory routine with medium volumes, from the dilution series to preparing buffers. The stand supplied ensures a tidy workstation from the start.3 pipettes for the complete rangeThe Starter Kit Midi combines 3 Transferpette S single-channel pipettes with variable volume: the D-20 for 2-20 µl with an increment of 0.02 µl, the D-200 for 20-200 µl with an increment of 0.2 µl and the D-1000 for 100-1000 µl with an increment of 1 µl. Together the devices cover the range 2 µl to 1000 µl. A matching pipette tip size is defined for each pipette, included in the set as 2x TipBox 2-200 µl, 1x TipBox 50-1000 µl.Precision under German legal metrologyAll pipettes in the set carry the DE-M marking under German legal metrology, and the accuracy testing is based on DIN EN ISO 8655 with three test points per volume range (100, 50 and 10 percent of the nominal volume). At the respective nominal volume, the accuracy A lies, depending on the model, between ±0.8 % and ±0.6 %, a level of accuracy that matters in dilution series and quantitative analyses. The accuracy A describes the deviation of the mean dispensed volume from the nominal value, the coefficient of variation CV the scatter of several repetitions at the same volume, both values increase towards the lower end of a volume range.One-handed operation and tool-free adjustmentEach pipette in the set can be operated with one hand, from volume adjustment to tip ejection, and a lock (UNLOCK/LOCK) protects the setting during series work. If a pipette deviates from the factory setting, it can be readjusted without tools via Easy Calibration, and an adjustment slider under the label window makes this visible.Autoclavable fully assembledAll pipettes in the set tolerate autoclaving completely, at 121 degrees Celsius and 2 bar, with a holding time of at least 15 minutes according to DIN EN 285, in the fully assembled state and without prior dismantling.Quality certificate and warranty includedA quality certificate (Performance Certificate) is included in the Starter Kit Midi, documenting the testing. Brand grants a three-year warranty on the single-channel pipettes of the Transferpette S series.Which laboratory this combination suitsA routine laboratory covering dilution series, buffer preparation and general sample preparation in the medium volume range rarely goes below 2 µl or above 1 ml. The Starter Kit Midi bundles exactly this medium range, without also buying the extremes of the series.Advantage of the set over individual procurementThe Starter Kit Midi bundles 3 volume ranges in one order, instead of procuring each pipette individually and waiting for several delivery times. Since all pipettes come from the same series, they operate identically, an advantage when training new colleagues. The 3 shelf holders supplied hold all 3 pipettes within easy reach between two applications, instead of leaving them lying loose on the laboratory bench.Typical applicationsgeneral laboratory routine with medium volumes, from the dilution series to preparing buffersDilution series and reagent addition across several volume rangesInitial equipment for newly set up workstations as well as training and further educationWorkstations with changing staff and different volume requirementsTechnical detailsCompositionTransferpette S variable, single-channel, 3-piece Starter KitVolume range D-202-20 µl, increment 0.02 µlVolume range D-20020-200 µl, increment 0.2 µlVolume range D-1000100-1000 µl, increment 1 µlOperationOne-handed operation, volume lock UNLOCK/LOCKAdjustmentEasy Calibration, tool-free, adjustment slider under the label windowSterilisationAutoclavable fully assembled at 121 °C, 2 bar, at least 15 minutes according to DIN EN 285MarkingDE-MScope of delivery1x Transferpette S variable, D-20 (2-20 µl)1x Transferpette S variable, D-200 (20-200 µl)1x Transferpette S variable, D-1000 (100-1000 µl)2x TipBox 2-200 µl, 1x TipBox 50-1000 µl, filled3 shelf holders1x quality certificate1x silicone greaseIndividual requirements & procurement serviceIf your own requirements deviate from this composition, LT Laborhandel also offers the individual Transferpette S models and further sets with a different volume combination.
