  • Q:

    We would like to order the compression spring for inside this pipette. WE have a bag that has part number 00238GP which might be the order number. Can you please verify?

    Comments about Pipette Pumps with rapid release lever, red, 25 mL:

    The pump works well, but the wheel is not inifinite control, it moves in steps, so controlling to fill to a specific line takes a little practice. That said it holds the vacuum nicely and releases nicely. Also comfortable in your hand; probably harder for people with small hands.
