VWR® Disposable Serological Pipets are available in sterile or nonsterile formats, with a variety of packaging options to choose from.

These pipets have a uniform pulled tip and are calibrated to deliver to the tip, with two rings near the top denoting that the small amount remaining in the tip after free delivery has ceased must be blown out and added to the main volume delivered. Negative graduations increase the versatility of the pipet. Pipets are available sterile and plugged or in bulk packs of nonsterile, non-plugged pipets. Nonsterile, non-plugged pipets feature a blue scale. Made from borosilicate glass in compliance with ASTM Specification E438, Type I, Class B glass requirements. Individually wrapped, multi-pack, and canister pack pipets are also designed from ASTM Specification E714.
