MVS Multichannel Verification System offers volume calibration down to the sub-microliter range (0.1 μl) and flexible plate mapping. These features enable labs with 8- and 12-channel manual or automatic pipettors to quickly and efficiently calibrate. A dual-dye, dual-wavelength, ratiometric absorbance method provides precise verification of liquid dispensing. Calculations are automatically performed for every well being tested, and a report is generated to show average channel volumes, target volume and various accuracy readings. This data enables labs to ensure compliance with testing protocols and to optimize productivity in drug discovery and development. The system can be used in any environment and verifies the performance of any XYZ liquid handler from any manufacturer.
