UV-Vis Spectrophotometers and Fluorometers

Fast, accurate DNA, RNA, and protein quantification for a single sample

The Invitrogen Qubit 4 Fluorometer accurately and quickly measures the concentration of DNA, RNA, or protein in a single sample. It can also be used to assess RNA integrity and quality. The easy-to-use touchscreen menus make it easy to select and run the assays you need, with results displayed in just a few seconds.

Fast, accurate DNA, RNA, endotoxin, and protein quantification up to eight samples

The Invitrogen Qubit Flex Fluorometer accurately and quickly measures the concentration of DNA, RNA, endotoxin, or protein in up to eight samples simultaneously. Compared to single-sample microvolume fluorometers, using the Qubit Flex system for multiple samples can reduce your time to data by up to 50%.

Sensitive and specific nucleic acid, endotoxin, and protein quantification assays

Invitrogen Qubit assays use target-selective dyes that emit fluorescence only when bound to their DNA, RNA, or protein target. They are more accurate than traditional UV absorbance, which can overestimate sample concentrations due to contaminants such as salts, solvents, detergents, proteins, and free nucleotides. Fluorescence measurements are also much more sensitive than UV absorbance, and Qubit Fluorometers can accurately measure dilute samples with significantly less noise.

Fast, accurate DNA, RNA, and protein quantification, one sample at a time

Thermo Scientific NanoDrop Ultra Spectrophotometers and Fluorometers are compact, stand-alone UV-visible spectrophotometers (select models also function as fluorometers) for measurement of highly concentrated samples across a wide variety of analytes without the need for dilution.
