These sterile disposable 10 mL PYREX® serological pipets are designed for the larger-volume user. They are calibrated (TD) with blow-out and are packed to permit easy access to several pipets at a time without contaminating the entire case. Similar to No. 7077, except multi-packed in plastic bags. New I.S.O. color-coding is printed directly on the tear strip for easy identification by size. Reference: ASTM E-714.
