Can the Multipette/Repeater E3/E3x be used in a cold room?

The Multipette/Repeater E3/E3x can be used in a cold room down to 5°C. Please note that the technical data for imprecision and inaccuracy only apply to the temperature range 20 - 25 °C.

What is the difference between Multipette/Repeater E3 and Multipette/Repeater E3x?

The Multipette/Repeater E3 has three functions: dispensing, automatic dispensing and pipetting. The Multipette/Repeater E3x has four additional functions: sequential dispensing, aspiration, aspiration/dispensing, and titration. Both models use Combitips advanced.

Is it possible to change the dispensing speed?

Yes. The dispensing speed and the aspirating speed can be set to 8 different speed levels.

How long does it take to recharge the battery?

Charging takes approximately two hours. It is possible to go on working while charging. The lithium-ion battery used has no battery memory effect.

How large is the capacity of the fully charged battery?

The lithium-ion battery allows a minimum of ten thousand dispensing steps or the filling of more than hundred 96 well plates with a 10 mL Combitip ® advanced in a row.

Are the Multipette/Repeater E3/E3x stable to UV light?

The Multipette/Repeater E3 and E3x are stable to UV light. In the event of prolonged irradiation with UV light, material discolorations may occur, but this does not affect the proper function of the Multipette/Repeater.

How can the Multipette/Repeater be calibrated?

To calibrate Multipettes/Repeaters in accordance with EN ISO 8655, three different volumes with ten measured values each have to be checked. These three volumes are the nominal volume (= the maximum volume to be dispensed), 50% of the nominal volume and 10% of the nominal volume of the Combitips advanced used. The checking procedure, the test conditions, and the limits in accordance with EN ISO 8655 are described in our "Eppendorf SOP for checking pipettes". The SOP is available on our web page.

What is the function of the aspirate and dispense mode?

Mode A/D allows the aspiration of an unknown volume and its subsequent dispensing in equal parts. The usage of the A/D mode is advantageous for several applications in protein biochemistry, molecular biology, cell biology, and microbiology. Detailed information on different possible applications is given in White Paper No. 25.

What is the function of the selection dial position options (opt)?

In options, different parameters can be edited. These are: Keylock, favorites, volume, brightness, language, personalization, interval, date and time, and screen saver.

How do I determine the volume values when calibrating gravimetrically?

The measuring values of the analysis scales are multiplied by the correction factor Z (see SOP pipettes). This takes into account the density of the water at the relevant temperature and the relevant air.

What does EN ISO 8655 cover?

ISO 8655 addresses the needs of suppliers, test houses, and users and specifies the general requirements for piston-operated liquid handling devices. It is structured in seven chapters: ISO 8655-1: Terminology, general requirements, and user recommendations ISO 8655-2: Piston pipettes ISO 8655-3: Piston burettes ISO 8655-4: Dilutors ISO 8655-5: Dispensers ISO 8655-6: Gravimetric method for the determination of measurement error ISO 8655-7: Non-gravimetric methods for assessment of equipment performance (titration, photometry)

What do the terms random error and systematic error mean in a pipette calibration?

The systematic error describes the deviation of the dispensed volume from the nominal volume or from the selected volume of the piston stroke device, and is determined by establishing the mean value of (usually) 10 measurements. The random error describes the mean variation of the dispensed volumes from the mean value of the dispensed volumes, and is determined by calculating the repeat standard deviation of (usually) 10 measurements.

Why are the Z factors listed in our SOP different from factors which can be derived from density reference values (of water)?

The Z factor is included in EN ISO 8655-6 and was incorporated into our SOP. As we understand it, it was incorporated in the standard by the Physikalisch Technische Bundesanstalt in Braunschweig. The Z factor describes the density of water at a particular temperature using a 5th degree polynomial. Furthermore, the density of water is corrected by the density of air (derived from air pressure) and a fixed correction value for balances. These corrections are the key reasons for the deviation from density values in various books of tables.

特征

精确、安全、多功能，长时间移液的理想选择！
在不影响精确度和准确度的情况下，为所有液体类型选Multipette E3择或E3x电动分液器。这些电动外置活塞式分液器是无压力、连续重复分液任务的理想选择，因为其重量轻、符合人体工程学的设计，并且采用简单的电机驱动，可降低疲劳和重复性劳损风险。Multipette E3和E3x拥有广泛的分液范围（1 µL至50 mL），有5000种不同的分液体积（增量低至100 nL），并搭配Combitips^® advanced外置活塞吸头一起使用。Multipette/Combitips系统具备自动吸头识别功能，适用于所有类型的液体，并且通过防止气溶胶从注射器式吸头中泄露，用户可以安全地处理危险液体和挥发性溶液。
Eppendorf 1978年发布了Multipette/Combitips分液系统，此后对其进行了多次改进。这是移液系统，仅需一次吸液就能进行多次分液操作。这一概念仍然是高效液体处理的驱动力，也是许多使用平板或系列试管的实验室的必备产品。自2023年起， MultipetteE3和E3x移液器以及Combitips advanced分液吸头均已获得ACT^®环境影响因子标签，表明我们环保生产的决心，有助于客户做出有利于环保的购买决策。

选择比E3拥有更多操作模式的Multipette E3x
虽然Multipette E3已经拥有三种主要操作（模式分液、自动分液和移液），可以满足了许多应用需求，但是Multipette E3x还提供了四种额外模式：按序分液、吸液、吸液/分液、滴定。两款机型均采用Combitips advanced吸头，确保简单、高效且无污染的液体处理。

将Combitips advanced吸头轻松连接到Multipette E3/E3x电动分液器，Multipette/Combitips在更短时间内完成精确分液
内置传感器可以识别吸头尺寸，并且体积会自动显示在显示屏上，从而消除耗时的体积计算和不正确的分液体积。Combitips advanced 有九种尺寸可供选择，提供更广泛的分液范围，包括最多112种不同容量，仅需一次吸液就能完成更多连续分液操作。
外置活塞式原理确保移液系统不受液体密度或粘度的影响，并且由于不形成气溶胶，因此可以更安全地分配含有放射性和/或有毒物质的溶液以及具有高蒸汽压的溶液。完成操作后，只需按下按钮即可弹出吸头，并在使用后进行处理——始终无污染！

需要处理高粘度或挥发性液体？
Multipette/Combitips 系统为精确分配所有类型液体提供了高级解决方案。使用Multipette E3/E3x电动分液器轻松给平板或系列试管加样，同时使用外置活塞式Combitips advanced吸头更大限度地提高移液精确度和准确度。使用Eppendorf移液器软件升级工具，您可以轻松升级电动Multipette，并随时了解最新的软件更新和功能！
