PYREX® 2.2mL Disposable Bacteriological Pipets, Multi-Pk, Str, Plugged, Grad

These sterile disposable 2.2mL PYREX® borosilicate glass pipets meet the requirements recommended by the American Public Health Association as shown in ”Standard Methods for the Examination of Dairy Products.” This pipet is very convenient when duplicate platings are to be made on the same medium or for plating differential medium for the determination of gram-negative bacteria, mold and yeast, or total plate count. They are designed for gravity feed (blow-out is not required). These cotton-plugged pipets are packaged in sterile bags. This allows the use of several pipets at a time without contamination of the entire case. New I.S.O. color-coding is printed directly on the tear strip for easy identification by size.
