ali-Q 2 In-lab Calibration Protocol
The ali-Q 2 series pipet controllers include calibration software which allows users to perform in-lab calibration
adjustments
as needed.
Perform Initial Performance Verification:
In order to calibrate the ali-Q 2, gravimetric measurements from the unit will first need to be obtained. Follow the
instructions for a Performance Verification below to determine the initial/current % error at 0.5 and 5.0 mL and record
the 2 numbers to use in the following calibration procedure.
Worksheet
Determine the current accuracy of your ali-Q 2 by taking the average of
4
gravimetric measurements at 0.5 mL and 5.0
mL (or 0.3 and 3.0 mL for the ali-Q 2 LS).
NOTE:
We recommend using speed 7 for taking measurements with the ali-Q 2 VS.
Use this table to record the values. Then calculate the avg. at each volume.
