The MTC Bio P4111-14 5mL Large Bulb Transfer Pipettes, Graduated, Sterile, 20 per Package, Pack of 500, are unbreakable, one-piece pipettes that are designed to eliminate contaminated rubber bulbs, broken glass and exposure to infectious materials. They are made of ultra-clear, low density polyethylene (LDPE) and are ideal for microbiology, blood banking, hematology, immunology, and urinalysis. The sterile pipettes are excellent for tissue culture application. Their low-affinity surface reduces sample, cell or protein loss.

The pipettes can be heat sealed for airtight sample storage. Their uniform drop size can be used for reproducible spotting of gels and TLC plates, and for dispensing into test plates, ID strips, PCR tubes or 96 well plates.
