The new "PROPIPETTE" eliminates the dangerous practice of using the mouth to draw liquids into pipettes. They are simple to use and the operator quickly becomes proficient so that the liquids can be delivered quickly, precisely and safely. Measurement precision is extremely high—0.01 cc. The instrument has three agate-ball valves which operate independently and the entire procedure can be done entirely with one hand.

APPLICATIONS: Transferring corrosive, toxic, infectious, ill-smellins liquids sucK as acids, alkalies, cyanides, sulphides, bacteriological cultures, chloroform, ether, urine, blood, excrements, dyes, etc. Skimming off with precision minute quantities of liquid floating above a sediment without danger of mixing, as in serum from red blood corpuscles and micro-anarysis. Skimming off and measuring the liquid floating above a chemical precipitate. Transferring sterile samples of liquids to other tubes and containers. Transferring radioactive solutions.
