The EZ1 Advanced XL Test Card provides protocols designed to evaluate the pipetting accuracy of the EZ1 Advanced XL. The EZ1 Advanced XL pipets either 100 µl or 500 µl of water from one set of tubes to another. Pipetting accuracy should be within defined specifications of ±8 µl for 100 µl, corresponding to pipetted volumes in the range of 92–108 µl and ±40 µl for 500 µl, corresponding to pipetted volumes in the range of 460–540 µl. An additional protocol on the EZ1 Advanced XL Test Card describes how to test the tip adapters for liquid leaks.
