The Mohr & Serological Pipette
Figure 1. Comparison with the air-displacement and optimistic-displacement pipettes. Panel A displays the Functioning theory of air-displacement pipettes Together with the piston built-in to the decrease part of the pipette and an air cushion concerning the sample and the piston.
quite a few modern variations perform by making a partial vacuum previously mentioned the chamber in which the liquid is held.
