Question
What is the difference between a Mohr and Serological pipette?
Summary
Definition of Mohr and Serological pipettes.
Answer
A Serological pipette is a graduated pipette in which the calibration marks extend all the way to the tip. When an amount of fluid is drawn back the entire amount in the pipet is dispensed so that the pipet is empty.
A Mohr pipette is a graduated pipette in which the calibration marks do not extend to the tip but at a point above the tip. Fluid is drawn up to a graduation mark and then dispensed to the zero mark, not completely evacuating the fluid from the pipette.
