We have been using the Denovix DS-11 for some time now, and we are positively surprised by the versatility of the microvolume spectrophotometer! It measures both absorption and fluorescence. We often use absorption at 260/280 and 230/260 ratios to measure the purity of DNA after isolation.
Before Illumina sequencing, it is useful to check the sample with the fluorescence function to measure the exact DNA concentration of the sample. You can also add peripheral equipment, which works well. We are very pleased with the DS-11.
