These unbreakable, one-piece dropping pipettes eliminate contaminated rubber bulbs, broken glass and exposure to infections materials. These disposable dropping pipettes are made of ultra-clear, low density polyethylene (LDPE) and are ideal for microbiology, blood banking, hematology, immunology, and urinalysis. Their low-affinity surface reduces sample, cell or protein loss. They can also 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.
