Lyophilized dye enables you to check the pipetting accuracy when you have a test solution that may have a higher or lower viscosity compared to water. Simply mix the lyophilized dye in your sample liquid, then use this solution with the Checkit Go to measure the amount of the sample liquid that your automated liquid handler robot will actually dispense. Using this sample solution removes errors introduced by the differences in viscosity and/or surface tension between your sample liquid and water.
- Resuspend the dye pellet in 4mL of your test solution.
- Use the resuspended solution to determine the accuracy of your robotic liquid handling system or hand pipettes.
