Question
How can a pipette be checked to deliver the correct volume without an analytical balance?
Summary
Checking pipette volume without a balance
Answer
The Pipette validation kit (Product # LCA722) is a kit composed of cuvettes/vials filled with a solution of a defined colour. Adding a volume of 2 mL causes a dilution of the colour in the vial, the absorbance is measured and then compared to the theoretical value.
Pipetting errors of more than 2% can be detected by using this method.
