UV/Visible Life Science Spectrophotometer

The Biowave II diode array spectrophotometer offers all the benefits described for the Lightwave II with the addition of key life science applications. There are pre-defined methodologies for nucleic acid quantification (DNA, RNA and oligionucleotides), protein assays (BCA, Biuret, Bradford and Lowry) and for cell culture density measurements. The visualision of the nucleic acid scan is particularly useful, especially for RNA samples where impurities may be present in the 230 nm region, yet not have an adverse effect on the A260/A280 ratio. The system is compatible with disposable low volume UV cuvettes The combination of the life science methods with the rapid scanning, kinetics and concentration capabilities of the Biowave II make it a very useful addition to any molecular biology laboratory. In kinetics mode, the basic plot of absorbance against time may be supplemented with the result for äA/min plus the correlation coefficient is also calculated for the duration of the assay. This slope may be multiplied automatically by a factor to convert it directly to rate of reaction. Once again, all results may be printed to an optional integrated high quality printer for a permanent record or via either a USB or Bluetooth connection to a suitable PC for storage or printing. The Biowave II+ is a higher esolution 3nm bandwidth version.
