This specification covers the design and dimensional requirements for four types (Types I, II, III, and IV) of disposable bacteriological (Pasteur-type) nonvolumetric glass pipets suitable for replicate dispensing of drops of solutions and suspensions for laboratory purposes. The pipets shall be made of good quality, clear glass of either Type I, Class A or B (borosilicate), or Type II (soda lime). They shall be of a one-piece glass construction and each type shall correspondingly meet the requirements for overall length, body length, body outside diameter, body wall thickness, top-to-constriction distance, and tip inside diameter.
