Non-Sterile Disposable Serological Pipets • Pipets are non-plugged and non-sterile, with a uniform pulled tip • Calibrated to deliver to the tip • Two rings near the top indicate that the small amount remaining in the tip after free delivery has ceased must be blown out and added to the main volume delivered • Blue scale with negative graduations to increase the versatility of the pipet • Manufactured to ASTM E1380 for color coding • Bulk packed in sealed plastic bags • Manufactured from 51 expansion borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class B requirements Part Number Capacity; Tolerance (mL) Graduation Intervals (mL) Case Qty 72120-1110 1; ± 0.03 0.1 1,000 72120-11100 1; ± 0.03 0.01 1,000 72120-21100 2; ± 0.06 0.01 500 72120-5110 5; ± 0.15 0.1 500 72120-10110 10; ± 0.30 0.1 500 Sterile Disposable Serological Pipets, Shorties These “Shorty” pipets are ideal for use in tissue culture work and other procedures performed under a fume hood or in other confined areas. • The pipets have “negative” graduations to increase the versatility of the pipet • Calibrated To Deliver (TD) • Packaged in color-coded, paper/plastic individual wrap for speed and accuracy in selecting the correct size • Overpacked in convenient, dispensing shelf-packs • 72110 series is packaged in a multi-pack bag so one or several can be removed without contaminating the entire pack • Manufactured from 51 expansion borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class B requirements

Proper Method of Delivering Contents • Draw liquid above top graduation using bulb or equivalent device. • Use forefinger (not thumb) for level control • Wipe any drops off outside surface only • Zero meniscus at top graduation • Drain pipet with tip touching side of receiving container • After emptying pipet, wait two seconds and remove pipet tip sideways and away from vessel wall. Do not remove the tip with an upward or downward motion • Only serological type pipets require last drops to be “blown out.” Do not “blow out” volumetric (transfer) or measuring (mohr) pipets, as they are calibrated for after “touch-off” to remain.
