NanoDrop – Precision in Microvolume Spectrophotometry

NanoDrop is a leading brand of microvolume spectrophotometers, widely used in molecular biology, genetics, and biochemistry laboratories. These instruments allow researchers to measure nucleic acids (DNA, RNA), proteins, and other biomolecules with high accuracy using only small sample volumes. The NanoDrop technology, developed by Thermo Fisher Scientific, has revolutionized spectrophotometry by eliminating the need for cuvettes or capillaries.

How NanoDrop Works

Unlike traditional spectrophotometers, NanoDrop instruments use a pedestal-based sample retention system. A small droplet (1–2 µL) is placed between two optical surfaces, forming a liquid column. check out here. This eliminates the need for dilution and enables direct absorbance measurement.

Key advantages of the NanoDrop technique include:

• Minimal sample consumption (as little as 0.5 µL)


• Fast measurement times (typically under 10 seconds)


• No cuvettes or additional consumables required


• High sensitivity and accuracy
