Artel will present its MVS (Multichannel Verification System) at European Lab Automation on June 30 - 1 July 2011 at the CCH - Congress Center in Hamburg, Germany.
The MVS system provides accuracy and precision data documenting the volume-transfer performance of each channel of any automated liquid handler.
Able to function within a volume range of 0.01 to 350ul, the system provides automatic reporting of volume statistics on a tip-by-tip and well-by-well basis within minutes of dispensing.
It can be fully integrated into existing automated quality-control protocols and implemented by a technician of any skill level.
The Artel MVS offers laboratories the ability to implement regular calibration programs and verification checks for volume-transfer accuracy and the precision to quickly identify those robotic systems that are failing or are misadjusted for the assay in question, reducing liquid-handling error.
The MVS uses ratiometric photometry, a technology that measures the absorbance values of two dye solutions to calculate the dispensed volume in each well of a microtiter plate.
Measurement results are traceable to the International System of Units (SI) through NIST reference standards and the system is portable and does not require rigorous environmental controls.
In addition, the MVS is compatible with 96-well and 384-well microtiter plates, and can verify automated liquid handlers with 1-384 dispensing tips.
The photometric method is applicable for all volume measurements and is particularly successful for small volumes.
In one single measurement, the MVS uses ratiometric photometry to calculate both the precision and accuracy of the transferred volume for each tip of the liquid handler.
Volume verification using the MVS can be performed by using assay-specific reagents, such as dimethyl sulfoxide (DMSO).
