Yes, Eppendorf pipettes are resistant to acetonitrile but care must be taken to avoid damage to printing and display window.

​All Eppendorf bio-based products fulfill the same standards as fossil-based Eppendorf consumables: They perform the same mechanical and chemical stability and have the same low leaching profile. A detailed overview of quality criteria for Eppendorf products regarding raw material and production is provided in APPLICATION NOTE NO. 056.

Yes, for the high-volume pipettes 2.5 mL, 5 mL and 10 mL. Nose cone filters are filters which are pushed into the nose cone.

As the liquid normally does not contact the pipette, the application is possible. If the material of the pipette gets in direct contact for a longer time the tip ejector can be damaged (it can be changed as a spare part).

"Eau de Javel" is the old name for a bleach solution containing potassium hypochlorite (KOCl). Solutions containing NaOCl, which ought to behave very similarly to KOCl in chemical terms, have been tested. These solutions can be used with our tips and for decontaminating the surface of Research pipettes. Commercially-available surface decontaminants like RNase AWAY and DNA AWAY are also possible. If the surface is treated for less than an hour, subsequent cleaning with distilled, sterile water is required. After an extended period (a few months), plastic parts may be affected by the NaOCl.

No.

The upper part of the multi-channel pipette can be used with both 8-channel and 12-channel lower parts, insofar as the volume sizes are taken into account.

Compared to the multi-channel pipette, the single-channel Research pro 20 - 300 µl pipette has slight differences at the slowest (for gel loading) and fastest speeds. However, this has no effect on the "Mix" function.
