Plastic, disposable pipettes are practical in programs wherever sterility is really a prerequisite. Serological Pipet Fillers assist to aspirate and dispense liquids correctly and with precision. The velocity of both aspiration and dispensing could be adjusted independently to operate with a variety of liquids.
