Our Part Numbers Decoded

Our Part Numbers Decoded

First, if you’ve got the manufacturers item number, plug it in our search box and you’ll find it. 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.


The Pipette Supplies Brand

Why our brand? We prefer why not? Why not benefit from quality products at a lower cost? We’re playing the long game.

We’ve chosen the best.  We offer economical quality parts, tools and batteries for many models of pipettes. Each batch of our branded products goes through rigorous QC testing. Our products 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. You’ll probably find it, but if that doesn’t work, send us an image or give us a shout. There are several pipette flavors 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 tell us so we can help others.
