Eppendorf Research plus single-channel pipette set, pack of 3, 100–1,000 µL / 0.5–5 mL / 1–10 mL, 3123000926

Those who switch between several volume ranges in their day-to-day laboratory work often use three separate pipettes rather than just one. The Research-plus Set 3123000926 brings together precisely this combination: one pipette for 100–1,000 µL, one for 0.5–5 mL and one for 1–10 mL, 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 preparation, for example in molecular biology or when preparing dilution series.

Typical applications

The Eppendorf Research plus 100–1,000 µL / 0.5–5 mL / 1–10 mL is suitable, amongst other things, for:

• Preparing larger volumes of buffers and media
• Filling test tubes and culture flasks
• Filling reaction vessels and cuvettes
• Media changes in cell culture
• Sample aliquoting and sample preparation

Features and handling

For 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 Fortron PerfectPiston is housed in a base 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.

Comparing Research plus, Reference 2 and Xplorer

When choosing between the Research plus, Reference 2 and Xplorer, the frequency of volume changes is the key deciding factor. The Research plus sets the volume mechanically via a setting wheel, 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 range

If the volume range of this pipette does not fully meet your requirements, it is worth taking a look at neighbouring Research plus models, for example the Eppendorf Research plus G single-channel pipette, fixed, 200 µL, blue, 3124000091 and the Eppendorf Research plus single-channel pipette, variable (1–10 mL), 3123000080. 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 maintenance

The upper and lower sections can be autoclaved when assembled at 121 °C and 1 bar gauge pressure 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 °C and relative humidity of 10 to 95 %; during operation, the temperature range is 5 to 40 °C 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 is excluded.

Set or single pipette

A 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 suffice.

Frequently asked questions

Is the Eppendorf Research plus 100–1,000 µL / 0.5–5 mL / 1–10 mL autoclavable?
Yes. The upper and lower sections can be autoclaved when assembled at 121 °C and 1 bar gauge pressure for 20 minutes without the lower section needing to be dismantled. The filter sleeve and protective filter are autoclaved separately.

Is re-greasing necessary after autoclaving?
No, according to the manufacturer, there is no need to re-lubricate the pistons after autoclaving. However, a gravimetric check of accuracy afterwards is recommended.

Can the three pipettes in the set be reordered individually?
The pipettes included in the set correspond to the respective individual models from the Research plus range and can also be requested individually from us if required.

Which pipette tips are compatible with the Eppendorf Research plus 100–1,000 µL / 0.5–5 mL / 1–10 mL?
According to the operating instructions, epT.I.P.S. for each individual pipette.

Is the pipette an in vitro diagnostic device?
No. Eppendorf lists the Research plus as a pipette for general laboratory use; it does not carry CE-IVD marking. Eppendorf discontinued the earlier IVD version under Directive 98/79/EC in early 2022, when Regulation (EU) 2017/746 replaced the Directive. According to the manufacturer, the pipette is technically unchanged and may be used for general laboratory applications, including IVD applications.

To whom should warranty claims be addressed?
To the relevant Eppendorf authorised partner. 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, a secondary adjustment is intended for the Research-plus range. Details are set out in a separate Eppendorf adjustment document.
