NanoDrop

The Thermo Scientific NanoDrop One Microvolume UV-Vis Spectrophotometer is designed to help research scientists achieve success in downstream applications by accurately quantifying DNA, RNA, and protein samples using only 1–2 µL.
NanoDrop spectrophotometers work on the principle of ultraviolet-visible spectrum (UV-Vis) absorbance. Nucleic acids absorb light with a peak at 260 nm. Purified proteins absorb light at a peak of 280 nm, while peptides and proteins that lack tryptophan and tyrosine residues absorb at a peak of 205 nm.
The detection limit (a NanoDrop is accurate- to it’s detection limits) of dsDNA, ssDNA and RNA will differ, and user experience will depend on the solution being used as a solvent for whichever type of nucleic acid you are measuring.
The Thermo Scientific NanoDrop One/OneC Spectrophotometer is a compact, stand-alone UV-visible spectrophotometer for measurement of highly concentrated samples across a wide variety of analytes without the need for dilution.
