The Thermo Scientific NanoDrop 2000 spectrophotometer is a micro-volume UV-Vis spectrophotometer designed for the quantitative and qualitative analysis of nucleic acids, proteins, and other biomolecules. It allows accurate measurement of sample concentrations with as little as 1-2 µL of sample volume, making it highly efficient for limited or precious samples. The NanoDrop 2000 uses patented sample retention technology, eliminating the need for cuvettes or capillaries, while its broad wavelength range (190-840 nm) enables the detection of a variety of analytes. The instrument provides quick, highly reproducible measurements with built-in software for data analysis, including nucleic acid purity assessment (A260/A280 ratios) and protein quantification. Its user-friendly interface and compact design make it ideal for routine laboratory applications in molecular biology, biochemistry, and proteomics research.
