Thomas 136030PLTS Polyethylene 4.5mL Transfer Pipette, Narrow Stem, 155mm Length (Case of 5000)

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. An extensive selection of capacities, lengths and tip styles are offered to accommodate different industry needs. Non-sterile transfer pipets are packaged in a unique dispenser box. This convenient box is small and compact and ideal for bench-top use. The hinged front panel opens for quick access to the pipets and can be closed when not in use to keep the contents clean. 25 drops per milliliter, 1mL bulb draw, no graduated.
