Multichannel Verification System facilitates improved assay results
Artel is launching the new MVS Multichannel Verification System, an objective performance assessment and optimization tool for automated liquid handlers. The MVS offers accuracy and precision information for any liquid handling device with up to 384-channels, allowing for confidence in assay data.
The MVS provides accuracy and precision data traceable to the International System of Units (SI) through reference standards developed and maintained by the National Institute of Standards and Technology (NIST) in an easy-to-use system that rapidly and automatically documents the volume dispense performance of each channel of an automated liquid handler for aqueous or user defined solvents. Able to function within a volume range of 0.01 μL to 350 µL, the MVS can be fully integrated into existing automated quality control protocols and implemented by a technician of any skill level. Based on ratiometric photometry, the MVS measures the dispensed volume from any 1-, 2-, 4-, 6-, 8-, 12-, 16-, 24-, 96-, or 384-channel liquid delivery device in minutes.
With the MVS enhancements, the system can now provide volume measurements with an even higher degree of accuracy and precision. For devices utilizing 384-well plates, MVS precision and accuracy tolerances have been reduced to 0.8 – 1.4% and + 2.5 – 3.5% respectively, depending on the volume range. For devices dispensing into 96-well plates, the precision and accuracy specifications have been tightened to 0.4 – 0.5% and + 2 – 3% respectively, depending on the volume range. With these new specifications, laboratories can decrease the uncertainty in their liquid handling operations for overall improvements in data quality.
In addition, the MVS can now be implemented in laboratory processes for 6-channel liquid handling devices and 4-channel liquid handlers facilitating performance assessment with greater ease and accuracy.
“Our goal as the leader in liquid handling quality assurance is to enable laboratories to strengthen their quality control programs without spending significant time or effort. The MVS has already become the industry standard in liquid handling quality assurance worldwide. Our aim today is to make its implementation and use by laboratories as easy as possible,” said Tanya Knaide, MVS Product Manager, Artel. “We also recognize the increasing number of laboratories working with extremely small volumes. With the enhanced MVS, these laboratories can ensure that their automated liquid handlers are dispensing even small volumes to specifications, maximizing efficiency and assay productivity.”
