These unbreakable all-in-one pipets eliminate the hazard of broken glass and exposure to infectious materials. Molded from see-through low density polyethylene, they are inert to biological fluids and most acids. The low-affinity surface reduces the loss of cells and valuable proteins due to binding. Transfer pipets can be sealed and refrigerated, and will work well whenever there is a need for quick, safe fluid transfer. Can be gas sterilized.
