IKA R 1825 Plate Stand for RW 20 digital Overhead Stirrer, Height 560 mm, 0003160000

Promotional item of the IKA Specials Q4/2026, valid until 31 December 2026. The struck-through price is IKA's recommended retail price. Our promotional price is net.The IKA RW 20 digital stirrer (MPN 0003593000) is the digital further development of the proven RW 20 series and combines a mechanically controlled drive with an LED digital display for the speed. Anyone who regularly has to move stirring volumes of up to 20 litres of water in the laboratory and wants to switch between powerful, low-speed and fast, high-speed stirring will find a robust working tool for daily use here.Mechanical gearbox with two speed rangesThe RW 20 digital has a gearbox with two speed ranges that is switched manually by lever. Range I covers 60 to 500 rpm and delivers a high torque of up to 150 Ncm at the stirring shaft, suitable for highly viscous media of up to 10,000 mPas, pastes or larger volumes. Range II extends from 240 to 2,000 rpm and is suitable for low-viscosity media and fast dispersing. At a mains frequency of 50 hertz, the ranges are 60 to 500 rpm (range I) and 240 to 2,000 rpm (range II), and at 60 hertz correspondingly 72 to 600 rpm and 288 to 2,400 rpm. The maximum torque at the stirring shaft is 150 Ncm at 100 rpm and falls to 24 Ncm at 1,000 rpm; for a short time, an overload of up to 300 Ncm is even permissible at 60 1/min.Precision through LED digital displayWhile power transmission is mechanical, the integrated LED digital display on the front of the unit ensures a speed that can be read at any time and is reproducible. Setting is continuous, the setting accuracy is ±1 rpm, and the deviation of the speed measurement is ±30 rpm. The nominal torque of the drive is 1.5 Nm at a power consumption of 70 watts and an output power of 35 watts. The unit is designed for continuous operation at 100 % duty cycle.Pass-through hollow shaft for flexible height adjustmentA practical detail in everyday laboratory work is the pass-through stirring shaft (hollow shaft) with an internal diameter of 10.5 millimetres. It makes it possible to adjust the height of the stirring tool in the chuck (clamping range 0.5 to 10 millimetres) without having to realign the entire stirrer on the stand. The shaft is adjusted at standstill only. The arm for mounting on the stand has a diameter of 13 millimetres and a length of 160 millimetres.Typical applicationsWith its high torque in the lower speed range and a stirring volume of up to 20 litres, the RW 20 digital is technically suited for:Universal stirring tasks in the laboratory with changing batch sizesHomogenising and dispersing medium-viscosity to higher-viscosity media of up to 10,000 mPasTeaching and industrial laboratories with frequently changing usersRoutine operation in which it is necessary to switch between powerful and fast stirringSelection guide: stirring mechanically or electronicallyWithin the IKA stirrer range, the RW 20 digital described here, with its mechanically controlled drive, stands in contrast to the compact NANOSTAR 7.5 digital with electronic BLDC control. For stirring volumes of up to 20 litres, high torque in the lower speed range and robust continuous operation, the RW 20 digital is the right choice. If, on the other hand, no more than 5 litres are moved and a particularly compact, electronically controlled design is required, for example in tight space conditions in a fume hood, the NANOSTAR 7.5 digital is the more space-saving alternative.Differences from larger models of the RW seriesIf a stirring volume of 20 litres is not sufficient for the planned batch, IKA continues the mechanical RW series in larger sizes: the RW 28 digital for stirring volumes of up to 80 litres and the RW 47 digital for stirring volumes of up to 200 litres. For the majority of laboratory applications with batches of up to 20 litres, the RW 20 digital described here remains the more compact and more economical choice.Technical detailsMax. stirring volume (H2O)20 lMax. viscosity10,000 mPasSpeed controlmechanicalSpeed range I / II60 to 500 rpm / 240 to 2,000 rpm (at 50 Hz)Speed range I / II (60 Hz)72 to 600 rpm / 288 to 2,400 rpmSpeed setting methodcontinuousSetting accuracy / speed deviation±1 rpm / ±30 rpmSpeed displayLEDMotor power, input / output70 W / 35 WNominal torque1.5 NmMax. torque at the stirring shaft150 Ncm (at 100 rpm), 300 Ncm overload at 60 1/minTorque at the stirring shaft at 1,000 rpm24 NcmMax. power at the stirring shaft26 WPermissible duty cycle100 %Stirring tool mountingChuck, clamping range 0.5 to 10 mmHollow shaft, internal diameter10.5 mm, pass-through at standstillStand mountingArm, Ø 13 mm, length 160 mmIP ratingIP 20 according to DIN EN 60529Dimensions (W x H x D)88 x 294 x 212 mmWeight3.1 kgConnected load220 to 240 V, 50/60 Hz, 72 W (other voltage variants 100 to 115 V available)Scope of delivery1 x RW 20 digital1 x chuck keyA stand and a boss head for mounting as well as a suitable stirring tool are required for operation but are not included in the scope of delivery.Use, installation, maintenance and disposalAccording to degree of protection IP 20, the RW 20 digital is protected against solid foreign objects from 12.5 millimetres, and contact with splashing water must be avoided. The switching lever for the two speed ranges should only be operated with the motor stopped, as should the height adjustment of the pass-through hollow shaft in the chuck. For secure positioning, a sufficiently heavy stand with a stable boss head is recommended, especially when using the high torque in the lower speed range. At the end of its service life, the unit as electrical equipment does not belong in household waste but in the separate collection of waste electrical equipment.Individual requirements & procurement serviceOperating the RW 20 digital requires a stand (for example an IKA base plate stand), a suitable boss head and a stirring tool matched to the application, for example propeller, turbine, anchor or dissolver stirrers. A stirring shaft guard or a quick-release chuck can also be added if required. Through our procurement service, we will gladly put together a suitable stirring set-up for you from our range of stirring and mixing technology.Frequently asked questionsIs a stand included in the scope of delivery?No, a stand, boss head and stirring tool are required for operation but are not included in the scope of delivery.What is the maximum stirring volume possible with the RW 20 digital?Up to 20 litres of water, at a maximum permissible viscosity of 10,000 mPas.How do you switch between the two speed ranges?Via a mechanical lever on the front of the unit, which should only be operated with the motor stopped.Can the stirring tool be adjusted in height without moving the stand?Yes, via the pass-through hollow shaft in the chuck, adjustable at standstill.Is there an electronically controlled model as an alternative?For more compact applications of up to 5 litres, the electronically controlled NANOSTAR 7.5 digital is suitable.What happens if the stirring shaft is overloaded?For a short time, an overload of up to 300 Ncm at the stirring shaft is permissible at 60 1/min; beyond that, the load should be reduced.

A formulation batch in a beaker, an emulsion in a 500-millilitre flask, a batch of cell suspension for sample preparation: the T 25 digital ULTRA-TURRAX is the classic drive unit for all tasks in everyday laboratory work involving volumes between 1 millilitre and 2 litres. It covers a speed range from 3,000 to 25,000 revolutions per minute and is supplied as a drive unit only, without a dispersing tool, so that each laboratory can choose the appropriate tool geometry itself.Electronic speed control for reproducible batchesThe speed can be adjusted continuously between 3,000 and 25,000 rpm, with a deviation of just 1 %. An LED display shows the set value directly, whilst electronic overload protection and an error code display ensure reliable operation. Without a tool fitted, the unit remains comparatively quiet at 75 dB(A); the maximum viscosity is 5,000 mPas. For batches that alternate between low- and medium-viscosity phases, the speed can be readjusted at any time during the process without switching off the unit.Compact drive for the laboratory benchMeasuring 87 x 271 x 106 millimetres and weighing 2.5 kilograms, the T 25 digital takes up little bench space; the support arm measures 13 millimetres in diameter and 160 millimetres in length. The power input is 800 watts, whilst the power output is 500 watts. The unit operates at 220 to 240 volts at 50 or 60 hertz; a voltage variant of 100 to 120 volts is also available. Degree of protection IP 20 in accordance with DIN EN 60529 and a permissible duty cycle of 100 % round off the key technical specifications; the permissible ambient temperature range is from 5 to 40 °C with up to 80 % relative humidity.Assemble tools and stand as requiredAs no dispersing tool is supplied, each laboratory selects the geometry to suit the application: reusable stainless steel tools such as the S 25 N - 18 G - ST (Ident 0004447300) or the S 25 N - 25 G (Ident 0001713300), as well as disposable plastic tools in two sizes for applications where cross-contamination between samples must be ruled out. The S 25 KV - 25 G dissolver tool (Ident 0002466900) is suitable for more viscous media. For stationary operation, the R 1826 plate stand (ID 0003160100) with R 182 boss head (ID 0002657700) is available; for cleaning, the TS 25-3 Cleaning Tool (ID 0020003013) or the disposable tube S 18/25-ET50 (ID 0003452500) are suitable for cleaning.Typical applicationsHomogenisation of wastewater samples in environmental analysisDispersion tasks in laboratory reactorsWork under vacuum or pressure with suitable accessoriesSample preparation in medical researchSelection guide: individual drive unit or complete setIf you do not wish to put together the tool and stand separately, you will find the same technology, including accessories, in the T 25 digital Solution. For smaller tasks involving temperature measurement, the T 25 mini control ULTRA-TURRAX is the more compact alternative; for a housing design that is easier to clean, the T 25 easy clean digital is the choice. If the volume range of up to 2 litres is no longer sufficient for larger batches, the T 50 digital ULTRA-TURRAX handles volumes of up to 30 litres.Technical detailsMotor power input / output800 W / 500 WProcessing volume (H₂O)0.001 to 2 lMax. viscosity5,000 mPasSpeed range3,000 to 25,000 rpm, continuously variable (1 % deviation)Speed displayLEDNoise level (without tools)75 dB(A)Support arm diameter / support arm length13 mm / 160 mmProcess typebatchPermissible duty cycle100 %Permissible ambient temperature range / humidity5 to 40 °C / 80 % (up to 31 °C), decreasing linearly to 50 % at 40 °CIP ratingIP 20 in accordance with DIN EN 60529Connected load220 to 240 V, 50/60 Hz, 800 W (additional voltage variant 100 to 120 V available)Dimensions (W x H x D)87 x 271 x 106 mmWeight2.5 kgScope of deliveryT 25 digital ULTRA-TURRAX drive unitA dispersing tool is not included and must be selected separately to suit the specific application.Regulatory informationThis device is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

Not every application requires the full power of the larger T 18 units. For those who mainly homogenise low-viscosity samples and have limited bench space in their fume hood, the T 18 mini digital ULTRA-TURRAX offers a compact drive unit from the same series, which is noticeably lighter and smaller than its brushless counterpart.Compact design, lower power ratingThe drive unit measures 66 x 186 x 100 millimetres and weighs 1.8 kilograms, meaning it can be accommodated even in confined spaces. The motor draws 210 watts and delivers 160 watts; as with the larger model, the processable volume ranges from 0.001 to 1.5 litres (H₂O), with a maximum viscosity of 2,000 mPas. This makes the unit particularly suitable for low-viscosity samples; for more viscous samples, the more powerful T 18 brushless digital, with a maximum viscosity of 5,000 mPas, is the more suitable choice.Brushless motor with digital displayLike the larger models in the series, the T 18 mini digital operates with a brushless DC motor; the speed can be continuously adjusted between 3,000 and 25,000 revolutions per minute, with a deviation of 3 %. The speed and timer are controlled via a digital display. The unit is powered by 100 to 240 volts at 50 or 60 hertz; a USB-C interface connects it to a computer for remote control and documentation using labworldsoft.Tools from the S-18 seriesA dispersing tool is not included with the T 18 mini digital and is selected to suit the application, for example as a reusable stainless steel tool such as the S 18 N - 10 G or S 18 N - 19 G, or as a disposable plastic tool such as the S 18 D - 10 G - KS and S 18 D - 14 G - KS for switching between samples without the need for cleaning. For stationary operation, plate stands from the R-1825 series with R 182 boss head are available; for securing the instrument during operation, the RH 3 clamping holder is used.Cost-effective alternative for routine tasksCompared to the T 18 brushless digital, the T 18 mini digital offers slightly less power reserve but is nevertheless suitable for most routine tasks involving low-viscosity samples, such as in training or for recurring standard processes. Its compact dimensions and low weight of 1.8 kilograms make it easy to move between multiple workstations, without the need for a separate unit at each location.Typical applicationsHomogenisation of low-viscosity samples in a limited footprintSimple emulsification and dispersion tasks in routine work and trainingMobile use between multiple workstations thanks to its compact designReproducible short runs with a timerSelection guide: mini, brushless or with temperature measurement?If the power of the T 18 mini digital is insufficient, for example with higher viscosities or larger batches, the T 18 brushless digital, with 400 watts and a range of up to 5,000 mPas, is the more powerful alternative; it is also available as the T 18 brushless digital Solution, complete with tool and stand. For those who also need to monitor the sample temperature during dispersion, this function is available in the T-25 series, for example in the T 25 mini control ULTRA-TURRAX.Technical detailsMotor power input / output210 W / 160 WProcessable volume (H₂O)0.001 to 1.5 lMax. viscosity2,000 mPasSpeed range3,000 to 25,000 rpm, continuously variable (tolerance 3 %)Speed displayDigital displayMotor typebrushless, direct currentNoise level without tools75 dB(A)Boom diameter / boom length13 mm / 160 mmDuty cycle100 %Degree of protectionIP 30 according to DIN EN 60529USB interfaceUSB-CConnected load100 to 240 V, 50/60 Hz, 210 W (max. 250 W, standby 3 W), 48 V= / 4,500 mADimensions (W x H x D)66 x 186 x 100 mmWeight1.8 kgPermissible ambient temperature / humidity5 to 40 °C / 80 %Scope of deliveryT 18 mini digital ULTRA-TURRAX drive unitAccording to the manufacturer, a dispersing tool is expressly not included in the scope of delivery and is selected separately from the accessories range of the S-18 series.Regulatory informationThe unit is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

A batch volume of up to 1.5 litres covers many tasks in the laboratory where smaller benchtop units reach their limits, such as homogenising larger sample volumes in process development or mixing emulsions for quality control. The T 18 brushless digital ULTRA-TURRAX is the drive unit in the IKA T 18 series designed specifically for this application, featuring a brushless DC motor and a speed that can be continuously adjusted between 3,000 and 25,000 revolutions per minute.Brushless motor for continuous operationThe motor draws 400 watts and delivers 300 watts, designed for a 100 % duty cycle. Without an attachment fitted, the noise level is 70 dB(A) and the speed deviation is 2 %. The unit displays the speed and timer via an LED display. With a viscosity of up to 5,000 mPas, the T 18 brushless digital can also process thicker samples; the processable volume ranges from 0.001 to 1.5 litres, based on water.Compact boom, remote control via USBThe boom measures 13 millimetres in diameter and 160 millimetres in length. The drive unit itself measures 89 x 270 x 161 millimetres and weighs 3 kilograms, meaning it can be accommodated even in smaller fume hoods. It is connected to a 220 to 240-volt supply at 50 or 60 hertz with a power consumption of 400 watts; a voltage variant for 100 to 120 volts is also available. A micro-USB interface connects the drive to a computer, enabling remote control and experiment documentation using the labworldsoft software.Accessories for tool changes and documentationSeveral dispersing tools from the S-18 series are available for the T 18 brushless digital, including reusable stainless steel versions such as the S 18 N - 10 G and S 18 N - 19 G, as well as disposable plastic tools for switching between samples without the need for cleaning. For stationary operation, IKA supplies suitable bench stands from the R-1825 series with the R 182 boss head; for securing the instrument during operation, IKA offers the RH 3 clamp holder. Those working in regulated environments can also request factory calibration certificates.Typical applicationsEmulsifying and homogenising larger sample volumes in development and quality controlDispersing and suspending with particle size reduction down to the micrometre rangeReproducible series of experiments thanks to a timer and infinitely variable speed controlVarying tasks with different dispersing tools thanks to the quick-release couplingSelection guide: Drive unit only or complete set?Those who already have suitable dispersing tools in stock or prefer to make their own selection will find this drive unit a good choice; a tool is not included in the scope of delivery. Those who, on the other hand, want to be ready to go straight away will find the T 18 brushless digital Solution, which comes fully equipped with a tool, shaft and stand. For smaller volumes and simpler applications with lower viscosity, the more compact T 18 mini digital ULTRA-TURRAX is the more economical alternative. Those who regularly process larger batches of up to 2 litres will find the more powerful T 25 digital ULTRA-TURRAX, with 800 watts of motor power, to be the suitable successor model.Technical detailsMotor power input / output400 W / 300 WProcessing volume (H₂O)0.001 to 1.5 lMax. viscosity5,000 mPasSpeed range3,000 to 25,000 rpm, continuously variable (2 % deviation)Speed displayLEDMotor typebrushless, direct currentNoise level without tools70 dB(A)Boom diameter / boom length13 mm / 160 mmDuty cycle100 %TimerYes, LED displayPermissible ambient temperature / humidity5 to 40 °C / 80 %Degree of protectionIP 30 in accordance with DIN EN 60529USB interfaceMicro-USBConnected load220 to 240 V, 50/60 Hz, 400 W (100 to 120 V version available)Dimensions (W x H x D)89 x 270 x 161 mmWeight3 kgScope of deliveryT 18 brushless digital ULTRA-TURRAX drive unitAccording to the manufacturer, a dispersing tool is expressly not included in the scope of delivery and must be selected separately from the range of accessories, for example from the S-18 tool series.Regulatory informationThis unit is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

The IKA EUROSTAR 40 digital overhead stirrer (MPN 0020105155) represents the modernised, mechatronically optimised generation of universal laboratory stirrers for more demanding routine tasks in the higher viscosity range. With a footprint reduced by up to 23 % compared to previous models, this unit offers high functional density in a minimal space. Designed for a sample volume of up to 25 litres (based on water), the system reliably handles viscosities of up to 30,000 mPas. This makes it suitable for demanding mixing processes, homogenisation and reproducible test series in a professional B2B laboratory environment. Within the EUROSTAR series, the Model 40 digital bridges the gap between the entry-level Model 20 digital and the high-volume Model 60 digital: With the same stirring capacity of 25 litres as the Model 20 digital, it processes significantly more viscous media up to 30,000 mPas thanks to its higher torque (60 instead of 40 Ncm). Torque trend measurement for viscosity monitoring A key feature of the digital series is the integrated torque trend measurement. The system detects changes in the viscosity of the medium with an accuracy of ±6 Ncm and displays the relative viscosity trend on the LCD screen. This enables laboratory staff to draw conclusions about the status of the mixing process. Thanks to automatic speed adjustment within a range of 30 to 2,000 revolutions per minute, the stirrer maintains the selected speed even when viscosity changes. Ergonomic tool change and occupational safety The EUROSTAR 40 digital is designed for user-friendliness and process reliability in continuous operation. The integrated quick-release chuck allows one-handed changing of stirring tools without the need for additional tools. A lock button protects the system from accidental parameter changes whilst it is running. In the event of overload or blockage of the stirring element, independent safety circuits trigger an automatic shut-off. Connectivity and robust housing design With USB-C and RS232 interfaces, the overhead stirrer can be connected to a PC and controlled and documented via the labworldsoft laboratory software. The housing, made from coated die-cast aluminium and robust thermoplastic, meets degree of protection IP 54. The brushless DC motor operates with virtually no wear, is quiet (52 dBA) and is designed for a 100 % duty cycle in continuous operation. Typical applications Homogenisation of viscous media up to 30,000 mPas, for which the Model 20 digital no longer provides sufficient torque Mixing and dispersing in containers of up to 25 litres with increased viscosity, such as creams, gels or adhesive formulations Reproducible test series in research and quality control at a constant speed, even with viscous formulations Routine laboratory operation where greater stirring power is required without a larger footprint Technical details Drive & performance data Motor principleBrushless DC motor (BLDC) Motor power consumption118 watts Motor power output84 watts Max. power at the mixing shaft84 watts Power consumption186 watts Permissible duty cycle100 % (designed for continuous operation) Voltage range100 to 240 V / frequency 50/60 Hz Mixing & viscosity data Maximum mixing volume per mixing point (water)25 litres Maximum viscosity30,000 mPas Maximum torque at the stirring shaft60 Ncm Maximum torque at 30 to 200 rpm60 Ncm Max. torque at 200 to 2,000 rpm60 to 40 Ncm (linear adjustment) Rated torque0.4 Nm Speed & time control Speed range30 to 2,000 rpm (revolutions per minute) Speed adjustmentContinuously variable via electronic control Setting accuracy for speed±1 rpm Speed measurement deviation (n > 300 rpm)±1 % Speed measurement deviation (n < 300 rpm)±3 rpm TimerYes, built-in (setting range 1 to 6,000 minutes) Reversible direction of rotation / intermittent operationNo / No Metrology & Sensors Speed display & timer displayDigital LCD display Torque measurementIntegrated viscosity trend (trend mode) Deviation in torque trend±6 Ncm Temperature display / external sensor connectionNo / No Design & Geometry Mixing tool mountingQuick-release chuck (clamping range: diameters 0.5 to 10 mm) Hollow shaft (can be inserted whilst stationary)Yes (internal diameter 11 mm) Mounting on a standExtension rod (diameter 16 mm / length 220 mm) Housing materialCoated cast aluminium and thermoplastic Degree of protection according to DIN EN 60529IP 54 (splash- and steam-proof) Noise level without tools52 dB(A) Dimensions (width x depth x height)89 x 191 x 237 mm Net weight3.8 kg Permissible ambient temperature+5 to +40 °C (relative humidity up to 80 %) Scope of delivery 1 x IKA EUROSTAR 40 digital overhead stirrer (MPN 0020105155) 1 x integrated extension rod for stand mounting 1 x universal mains cable 1 x Detailed operating instructions / safety guide Individual requirements and procurement service We offer original IKA system peripherals to equip the EUROSTAR 40 digital mixing workstation: Stirring tools & shaft guards: Stainless steel and PTFE stirring elements (e.g. propeller stirrers, anchor stirrers, paddle stirrers) as well as the matching IKA R 401 stirring shaft guard with hinge (MPN 0020122349) Stand accessories: Sturdy IKA bench stands (e.g. R 1826) and boss heads (e.g. R 182) for securing the 3.8-kilogram drive Please make use of our technical procurement service to ensure your laboratory workstations are configured to meet your specific requirements.

Anyone who frequently homogenises samples in the laboratory will be familiar with the problem: a good drive alone is not enough; ultimately, it is the right tool that determines the final fineness and throughput. The IKA T 18 digital ULTRA-TURRAX (0003720000) is designed precisely with this in mind. It is supplied as a drive unit only, with a power consumption of 500 watts, which can be freely combined with various S-18 tools for coarse, fine or single-use applications. The LED display always shows the set speed between 3,000 and 25,000 revolutions per minute, which facilitates reproducible results across multiple test runs. Rotor-stator principle with high shear rates During dispersion, the tool draws the sample in axially and forces it out radially through the narrow slots between the rotor and stator. This briefly generates very high shear rates, which break down solid components and mix liquids into stable emulsions or suspensions. With an output power of 300 watts and a processable volume of 0.001 to 1.5 litres (based on water), the T 18 digital covers typical laboratory batches up to a maximum viscosity of 5,000 mPas. Stepless speed control with LED display The speed can be adjusted continuously between 3,000 and 25,000 rpm, with a deviation of just 1 % according to the data sheet. Unlike purely analogue controllers, the LED display shows the set value directly. Once process parameters have been determined, they can be noted down and reproduced exactly for subsequent experiments. With a permissible duty cycle of 100 %, prolonged continuous operation is also possible without the drive having to pause in between. The choice of tool determines the result The T 18 digital is deliberately supplied without a dispersing tool, as the most suitable tool depends heavily on the specific sample. The standard S 18 N - 19 G tool with PTFE bearings is suitable for coarse pre-shredding and tougher media, whilst the S 18 N - 10 G offers a narrower gap geometry for finer end products. Those who frequently work with varying samples that are potentially susceptible to contamination will find disposable plastic tools to be a practical alternative, as they rule out cross-contamination between batches from the outset. Typical applications As a standalone drive unit, the T 18 digital is particularly suitable for laboratories that already work with a variety of tools or switch specifically between several applications: Preparation of emulsions and suspensions in sample preparation Homogenisation of tissue samples in biology and life sciences research Mixing pigments and fillers into dispersions Routine tasks in quality assurance with varying tool configurations Setting up customised workstations through flexible combination with a stand and tool Selection guide for the T-18 range Drive unit only, complete set or just the tool? The four T-18 variants stocked by us differ primarily in terms of what is included in the scope of delivery and, in the case of the mini-drive, in terms of motor power.

Differences from the neighbouring series If you also require a brushless motor with a timer, the IKA T 18 brushless series offers the next step up: the T 18 brushless digital ULTRA-TURRAX as a drive unit without a tool, or the T 18 brushless digital Solution as a complete set. Both drive units operate with lower wear than the classic T 18 digital. An overview of all dispersers available from us can be found in the ‘Dispersers’ category; suitable tools are listed under ‘Dispersing Tools’. Application, set-up and maintenance For short-term manual operation, the T 18 digital fits comfortably in the hand; for longer or reproducible processes, it can be securely mounted on a stand, such as the R 1826 plate stand. Operation is permitted at an ambient temperature of 5 to 40 °C and a relative humidity of up to 80 % at 31 °C, decreasing linearly to a maximum of 50 % at 40 °C. The drive, with degree of protection IP 20, is not designed for use in damp rooms or outdoors. After each use, the tool used should be dismantled and, depending on the material, cleaned or sterilised before the next procedure begins. At the end of its service life, as an electrical appliance, the drive must not be disposed of with household waste but must be placed in the separate collection for waste electrical and electronic equipment. Individual requirements & procurement service In addition to the standard tools, we supply further accessories for the T 18 digital, such as stands, mounting elements or the Silentstream flow breaker to reduce air ingress during dispersion. Do you require a specific tool, a qualification document or assistance in selecting the right configuration? Through our procurement service, we can assist you with procurement and configuration. Frequently Asked Questions Is a dispersing tool included in the scope of delivery?No, the T 18 digital is supplied exclusively as a drive unit. A suitable tool, such as the S 18 N - 19 G, must be purchased separately. Which tool is suitable for coarse pre-grinding?For coarse applications and tougher media, the S 18 N - 19 G with PTFE bearings is the standard choice; finer end products can be achieved with the S 18 N - 10 G. How accurately can the speed be reproduced?The LED display shows the set value within a range of 3,000 to 25,000 rpm with a deviation of around 1 %, which facilitates the exact repetition of test series. Is a stand included in the scope of delivery?No; for continuous operation, we recommend a separately available stand such as the R 1826 plate stand. What is the difference between the T 18 digital and the T 18 mini digital Solution?The T 18 mini digital Solution features a more compact, brushless drive with lower motor power and comes as a set including the tool and stand; the T 18 digital described here is the more powerful drive unit without accessories.
