SEPGuides: Science Education Partnership: Micropipet Kit

SEPGuides is the go-to place for all SEP kit protocols and activities, as well as the posting area for announcements and program updates. If something is missing or you have an idea to contribute, please e-mail us at



Micropipets are a common laboratory instrument used for moving very small volumes of liquid, typically measured in microliters (µl), or 1/1000 of a milliliter. The micropipets and equipment in the kit are the same as those found in research laboratories.

Measuring very small metric volumes is essential for working with DNA samples, reagents, and enzymes like those found in the Gel Electrophoresis Kits.

Using micropipets offers an opportunity to consider several important concepts, especially accuracy and precision (or reproducibile vs. variable). Micropipets offer an engaging immersion in using metric volume measurements. For example, what's the volume of a red blood cell? How big are inkjet printer ink drops? How much liquid is in a tear drop?

Extra Activities

Gilson/Rainin Micropipets

Micropipet Kit #3 and #4 use Gilson/Rainin Micropipets.

Ulster Micropipet

Micropipet Kit #1 uses Ulster pipets.

Oxford Micropipet

Micropipet Kit #2 has Oxford pipets in unique ranges. 8-P10, 8-P100, and 8-P1000s.

Finn Micropipet

The Finn Micropipets are not used in any of the micropipet kits, but here is a reference for teachers using Gel #12 or borrowing extra pipets.
