Pipettes & pipettors have little accessory friends that help them do their job. You can buy them below.
Pipette/pipettor accessory friends include modular micropipette stands and reagent reservoirs.
Reagent reservoirs are truly variable. Both durable (polypropylene) and disposable reagent reservoirs are available, in sterile and nonsterile varieties. Reservoirs range in size from 10 to 100 mL, and some are subdivided. You can buy them in multiple package styles (depending on their sterility): individually wrapped, 5 per bag, or bulk packed.
