PYREX® Wide Tip Volumetric Pipets, Class B
Corning® wide-tipped PYREX® glass volumetric pipets were designed primarily for schools and laboratories where Class A tolerance as indicated by ASTM E-969 is not required. They have larger tip openings for faster delivery. It is primarily due to this faster delivery that accuracy tolerances are twice those specified for Class A volumetric ware. The wide tipped pipet features rugged construction with blue color-coded enamel graduations and markings. Reference: ASTM E-969. Non-sterile. Material: Borosilicate Glass Code 7800.
