What is a Mohr pipette?

The Mohr pipette is specifically designed as a measuring pipette that is not calibrated to deliver exactly the volume of liquid contained in it to the tip. Instead, it has graduation marks that allow for accurate measurement up to a certain point, but it does not dispense the entire volume stored within it when the liquid reaches the tip. This characteristic differentiates it from other types of pipettes, such as those that are designed to deliver fixed volumes or those that are calibrated to the tip.

This makes it suitable for applications where precise measurements are necessary, but complete transfer to another container is not required. Understanding how the Mohr pipette works is crucial for tasks that require careful liquid volume measurements in laboratory settings.
