PYREX® Reusable Volumetric Pipettes, Corning

These reusable pipettes are designed primarily for schools and laboratories where the Class A tolerance is not required.

• Larger tip openings for faster delivery
• Color-coded
• Colored graduations
• Accuracy tolerances are twice those specified for Class A volumetric ware

They are constructed to the same wall thickness and length as standard Class A volumetric pipettes, but have larger tip openings for faster delivery. Primarily due to the faster delivery, accuracy tolerances are twice those specified for Class A volumetric ware. Reference: ASTM E-969.
