These disposable glass pipets provide the performance of glass with the economy of plastic. Constructed of pharmaceutical, Type 1 borosilicate glass. pH change is reduced because pipets are chemically inert. Pipets will not warp or bow, and may be flamed. Leakage is prevented because of one-piece construction. Serological pipets have improved, baked-on graduations which are resistant to solvents and stay visible even through the longest analysis. Long, slender tips are highly readable. Pipet cotton plug will not “blow down”. Calibrated ""to deliver"" with blow-out. Two rings near the top indicate the last drop must be blown out after free delivery.
