The micro-volume spectrophotometer integrates a patented sample retention technology where sample volume as small as 0.5 µL can be analysed. In addition, it has a built-in cuvette capability to measure samples. Both modes of operation allow pre-configured methods for all common nucleic acid and protein concentration and purity measurements. Full spectral output is obtained in less than 5 seconds and it is easy to use. With small volume (0.5 µL) mode, large concentration range (2 ng/µL – 15,000 ng/µL dsDNA) without dilutions and with cuvette mode, extended concentration range (lower limit 0.4 ng/µL dsDNA) is possible. The cuvette mode also enables kinetic studies (time and 37°C temp) with stirring.
