Measuring Residual Volumes Remaining in a Plate After Sample Aspiration


The purpose of this application note is to demonstrate an alternative use for the Artel MVS® Multichannel Verification System. As opposed to measuring the accuracy and precision for a volume transfer of sample into a microtiter plate, the MVS is instead employed to measure the volume of sample left behind after attempting to aspirate off the entire sample from each well of a microplate, i.e., residual volume of sample. Measuring the residual volume after sample aspiration is a direct way for assessing the performance of the sample removal step. The experiments discussed herein show how residual volumes can be measured using the MVS.
