Pipettors, controllers

Designed for convenient and safe filling of pipettes of different types and manipulations with them. The pipettor design resembles the construction of a syringe and filling of the attached pipette is performed by creating a vacuum in the working cylinder of the pipettor when the piston is lifted. Lifting of the piston is carried out at rotation of a conveniently located toothed wheel thanks to what piston position at each moment of filling of a pipette, after its filling or at discrete draining is reliably fixed. This allows you to easily carry the filled pipette over the work table, from container to container, etc. without the threat of spontaneous leakage of liquid or its "throwing" into the cavity of the pipette.
