When choosing a multichannel pipettor, the user should make sure that it is fully autoclavable; in many pipettors, only the lower part can be autoclaved or the unit is not autoclavable at all. If autoclaving is done frequently, the pipettor, like the mLINE, should be fully autoclavable (numerous cycles) and should not need prior disassembling.
Calibration and in-house
When purchasing a multichannel pipettor, the user should make sure that it is CE marked, and can easily be calibrated and serviced in-house when necessary. In many multichannel pipettors, service is time-consuming, requiring extra tools and many different parts to be disassembled, cleaned, and reassembled in the correct order. This makes self-service practically impossible, especially if one broken tip cone requires a time-consuming change of the whole liquid end. For the user to be able to service the pipettor quickly and effectively, the multichannel pipettor should have individual piston/tip cone assemblies, and only 1-2 parts to be cleaned, as is the case with the mLINE. The calibration of the instrument has been made to be as user-friendly as possible. The calibration tool, which also acts as a tube cap opener, enables fast and accurate calibration. Most importantly, it allows fine adjustment. Due to a special transmission mechanism, even very small increments in calibration can be done easily and safely.
