Love this instrument

 

Average Rating 5.0

Application Area:

To evaluate both sample purity and exact concentration when working with purified PCR products and Next-Generation Sequencing (NGS) libraries.

By combining microvolume UV-Vis spectrophotometry with integrated fluorescence quantification in a single platform, we perform total sample quality control.

Review Date: 30 Sept 2026 | DeNovix

The best instrument for easiest quantification and purity checks

 

Average Rating 5.0

Application Area:

Quantification of RNA

We would quantify almost more than 10 samples at a time and it would be so quick and we don't even have to recheck that the results are so accurate. Coming to accessibility, it's so easy to use, we just had to tell our juniors how to use they wouldn't even need us to demonstrate it.
