The risk of liquid delivery error in molecular laboratories is growing as the average size of tested liquid volumes continues to diminish. Tasked with performing a large number of tests in a short amount of time, laboratories must balance productivity demands with the need for enhanced quality assurance. The PCS (Pipette Calibration System) and MVS (Multichannel Verification System) are tools that rapidly verify the accuracy and precision of liquid delivery devices. Able to measure small volumes at the benchtop level, these technologies provide assurance of data integrity.
