Globe Scientific 7 mL Bellows Transfer Pipet provides strong suction for use with viscous liquids. The accordion-shaped, high-capacity bulb of the Bellows pipet acts as a reservoir for filling and expelling liquids. Produced from a custom grade of low-density polyethylene (LDPE), these unbreakable one-piece pipets are used to draw and dispense liquids in controlled, reproducible drop sizes. Plastic transfer pipets are the perfect substitute for breakable glass Pasteur pipets, which can be a danger to laboratory personnel. And, because they are completely disposable, there is never any cross-contamination which is associated with reusable rubber bulbs.
