The VersaTray is a micro volume cuvette compatible with the VersaWave spectrophotometer enabling accurate, consumable free quantitation of sample volumes as low as 0.7 µl enabling the rapid and accurate quantitation biomolecules such a protein, DNA and RNA

The preparationand isolation ofnucleic acid and templatesfrom mini-preps, DNAkits, PCR reactions and gel elution for use in, for example, automated DNA sequencing often results in very low yields of between 1-5 ug of sample with very high native absorbance. Due to the narrow pathlength of the VersaCell such samples can be measured directly the VersaWave using as little as 0.7 ul sample and without the need for dilution, thereby saving valuable time. Quantification and purity analysis are therefore easily determined at any point during the preparation and isolation steps.

 

Due to the integratedbeam deflection and the use of fibre-optic cables, it is possible to measurethe sample directly on the surface of the optical window of the Tray. The cap with mirror providesa well-defined opticallight path and prevents the sample from drying up ensuring reproducible measurements as the sample will not be enrichedby evaporationof thesolvent. The VersaTray is available with a1mm pathlength (3-5ul sample) or 0.2mm pathlength (0.7-4ul)
