Description
Part of Biochrom, the WPA Biowave 3+ UV/Visible spectrophotometer is a life science oriented product with stored routines for nucleic acid quantification/proteins/cell density. The Biowave 3+ has a spectral bandwidth of 3nm.
These are pre-programmed methodologies for nucleic acid quantification (DNA, RNA and oligonucleotides), protein assays (BCA, Biuret, Bradford and Lowry) and for cell culture density (OD600) measurements. The visualisation of the nucleic acid scan is particularly useful, especially for RNA samples where impurities may be present in the 230nm region, yet not have an adverse effect on the A260/A280 ratio. The system is compatible with low volume UV cuvettes.
The combination of life science methods with the rapid scanning, kinetics and concentration capabilities of the Biowave 3+ 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 δA/min, plus the correlation coefficient is also calculated for the duration of the assay. This slope may be multiplied automatically by a factor to convey it directly to the rate of reaction.
