What is a micropipette?
Pipettes and micropipettes are used to measure and deliver accurate volumes of liquid. The difference between the two is that micropipettes measure a much smaller volume, starting at 1 microliter, while pipettes generally start at 1 milliliter.
What are the different types of micropipettes?
Within pipette calibration there are five widely used grades of pipettes, all of which have specific guidelines and requirements regarding use, testing, maintenance, and measurement. The five grades of pipettes include disposable/transfer, graduated/serological, single channel, multichannel, and repeat pipette. From the most basic transfer pipette dropper to the advanced repeat dispensing pipettor, the manner in which the equipment is handled will impact the accuracy of the test results.
What is the principle of micropipette?
Regardless of the manufacturer, micropipettes operate on the same principle: a plunger is depressed by the thumb and as it is released, liquid is drawn into a disposable plastic tip. When the plunger is pressed again, the liquid is dispensed.
What are the parts of a micropipette?
Components of a Micropipette
Basic parts of a micropipette include plunger button, tip ejector button, volume adjustment dial, volume display, tip ejector, and shaft.
Considerations for purchasing a pipette or micropipette?
When choosing pipettes for your lab, know what volumes you need to measure and transport to decide between regular pipettes and micropipettes. Decide whether you want to measure by hand or use pipettes that measure for you. If your lab uses multiwell equipment, you may want to choose a pipette with multiple tips.
