Our Part Numbers Decoded

Our Part Numbers Decoded

First, if you have the manufacturers item number, plug it in our search box and you’ll find the part you need. Now, here’s the secret to understanding our part numbers. The two-digit alpha code indicates the brand/manufacturer. i.e. EP =Eppendorf, GI=Gilson, LN=Labnet. Following that (after a space) is their part number. Pipette Supplies product numbers start with PS or without any alpha code for our legacy products.

What Kind of Pipette Do I Have?

Find out using our search box. Type the text that’s on your instrument including things like “multichannel”. Don’t bother with the serial number. If that doesn’t work, send us an image or give us a shout. There are several pipette models of each brand so it can be confusing.

Notes for Novices: Most mechanical and electronic pipettes are designed as a volume adjustable instrument instead of one fixed volume. Shorthand for the adjustable volume of an instrument is to use the high end of the volume range. For example, a pipette that is marked as a 100-1000uL is commonly referred to as a 1000uL Another point, 1000uL =1mL. Thus 5000uL=5mL, etc.

Who Makes What?

It’s complicated. There are several major pipette companies that design and engineer pipettes. Some manufacture pipettes themselves; some don’t. Typically, they source components to other specialty manufacturers (i.e. batteries, o-rings). Pipette companies also sell their designs to other entities that redesign them and sell them under other brands and models. Thus, there are over 400 models of pipettes on our site alone.

So we’ve deciphered who makes what by figuring out which pipettes have the same components and cross referenced them for you. Give us a shout if you get confused. If you find other pipettes to cross reference, please let us know so we can help others.
