Pipet fillers do away with the frequently hazardous practice of drawing liquids into pipets by mouth.

They work safely with toxic, infectious, odoriferous, radioactive, corrosive, or sterile liquids

Pipets are made out of 100% natural rubber with three stainless steel ball valves. For use with pipets of 1 mL to 45 mL capacity and 4–8mm outside diameter. A volume of 100 mL is attainable with repeated evacuation. With a simple three-step process, one can eliminate dangerous mouth pipetting.

Also useful for skimming off liquids floating above a chemical precipitate or sediment.
