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

The Multipette E3/E3x can be used in a cold room down to 5°C. Please note that the technical data for precision and accuracy only applies to the temperature range described in the Eppendorf SOP in compliance with the ISO 8655.

What is the difference between Multipette E3 and Multipette E3x?

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

Is it possible to adapt the aspiration and dispensing speed using the Multipette E3/E3x?

Yes, the aspiration and dispensing speed can be set to 8 different speed levels using theMultipette E3/E3x.

How long does it take to recharge the battery of a Multipette E3/x?

Charging the battery of a Multipette E3/x takes approximately two hours. It is possible to go on working while charging.

How large is the capacity of the fully charged battery of a Multipette E3/x? What is its lifetime?

The battery of a Multipette E3/xlife depends on various factors. The full battery capacity is sufficient for at least 500 aspirations and 10000 dispensing steps under the specified test conditions specified in the Instructions for Use. Under these conditions, the battery life is approx. 5 hours.

Are the Multipette E3/E3x stable to UV light?

The Multipette 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.

How can Multipette devices be calibrated?

To calibrate Multipette 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 dispensable volume), 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 "Eppendorf SOP" for Manual Dispensing Systems.

Are your pipettes free of nucleic acids?

We cannot guarantee that our pipettes are completely free of nucleic acids. While we maintain high standards of cleanliness and care during production, we do not implement specific measures to prevent nucleic acid contamination. To protect your samples from potential contamination, we recommend using positive displacement devices or filter tips, such as ep Dualfilter T.I.P.S. or ep Dualfilter T.I.P.S. SealMax.

How should warm or cold liquids be pipetted?

Best Practices for Pipetting Warm or Cold Liquids: Warm and cold liquids can behave differently than those at room temperature, requiring adjustments in pipetting techniques. Temperature differences between the liquid and the pipette can affect the air cushion, resulting in inaccuracies and imprecision that may exceed permissible error limits. To achieve optimal results, ensure that the pipette, tips, liquid, and surrounding air are all at the same temperature. For enhanced accuracy and precision, consider using a positive displacement device like the Multipette M4 or E3/E3x.

What does EN ISO 8655 cover?

ISO 8655-2022 is the global standard for piston-operated volumetric apparatus (POVA), including pipettes, burettes, dilutors, dispensers, and manual precision syringes, as defined by the International Organization for Standardization (ISO). It ensures standardized performance for manufacturers, calibration providers, and users.It is structured in 10 chapters: ISO 8655-1: Terminology, general requirements and user recommendations ISO 8655-2: Pipettes ISO 8655-3: Burettes ISO 8655-4: Dilutors ISO 8655-5: Dispensers ISO 8655-6: Gravimetric reference measurement procedure ISO 8655-7: Alternative measurement procedures ISO 8655-8: Photometric reference measurement procedure ISO 8655-9: Syringes ISO 8655-10: User guidance, user qualification and POVA qualification.

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

In pipette calibration, random error and systematic error are two key concepts that help ensure accuracy and precision in measurements. Random Error refers to the variability in measurements when the same volume is dispensed multiple times. It is also known as imprecision and is determined by calculating the repeat standard deviation of 10 measurements. These errors tend to scatter around the true value and can be minimized by consistent technique and proper training. Systematic Error is the consistent deviation of the measured volume from the selected/true volume, also known as inaccuracy and is determined by establishing the mean value of 10 measurements. Systematic errors can arise from defective or misadjusted devices and need to be corrected through proper calibration and maintenance.

Can the Multipette M4 and E3/E3x be autoclaved?

No, the Multipette M4 and E3/E3x cannot be autoclaved. The device can be decontaminated using a cloth moistened with 70% isoproanol as disinfectant. Then moisten the cloth with water, wipe down the housing and remove residual cleaning agent. Please ensure that no moisture can get into the device during cleaning.

Why can Multipette M4 and E3/E3x only be operated with Combitips advanced?

When using a positive displacement system, the dispenser and the dispenser tip must be perfectly matched. This will ensure that the high demands with regard to precision and accuracy are reliably met. Combitips advanced are perfectly matched to Eppendorf Multipette M4 and E3/E3x and M4. Combined with the center sleeve of the devices, accurate dosing for dispensing is supported in particular.

What material is the Multipette M4 and E3/E3x made of and what chemicals are they resistant to?

Please refer to the Operating Manuals on our homepage for detailed information on materials. The Multipette M4 has a chemical resistance sheet.

What does the “PhysioCare concept” symbol on the Multipette M4 and E3/E3x mean?

The symbol means that the Multipette M4 and E3/E3x have been developed in accordance with the considerations of the Eppendorf PhysioCare concept. With its three areas, the concept includes the whole range of ergonomics, not just a single element. Instead of focusing on a particular product feature, the products with the PhysioCare symbol provide a holistic solution. Further details on the PhysioCare Concept are available at www.eppendorf.link/physiocare.
