How to Use a Mohr Pipet

A Mohr pipette is a type of volumetric pipette used to measure and dispense liquid. A Mohr pipette differs from other volumetric pipettes, in that it generally has far more graduation measuring lines as part of the design. The Mohr style of the pipette is named after German pharmacist Karl Friedrich Mohr, who developed the device to transfer specific amounts of liquid in an accurate manner.
