Fluorometers are used for precise quantitation of biological molecules including nucleic acids and proteins in microliter (μl) samples.
Reliable Results,
Remarkable Value
Backed by world-renowned DeNovix reliability and support, the Helium 1 µL Spectrophotometer offers unparalleled value for money for both research and teaching labs.
Helium 1 µL Spectrophotometer
Affordable, Reliable Quantification
DS-Series instruments offer a wide choice of model offerings to find the perfect combination of measurement options for your lab’s sample QC. The Helium 1 µL Spectrophotometer enables easy biomolecule quantification in under 5 seconds with as little as 1 μL of sample. Where full UV-Vis spectral scans are not required, this device is the ideal choice for the analysis of nucleic acids and protein using absorbance measurements at 260 nm, 280 nm and 230 nm.
