Description
A Nano Spectrophotometer is a specialized instrument used to measure the absorption and concentration of nucleic acids (DNA, RNA) and proteins in very small volumes, typically in the nanoliter range. It is commonly employed in molecular biology, biotechnology, and life science research for various applications, including DNA/RNA quantification, protein analysis, and purity assessment of biomolecules.
Nano Spectrophotometer Model No: LI-5102 is a compact and precise instrument designed for quantitative analysis of DNA, RNA, and proteins in small sample volumes. Here’s a detailed description of its features and specifications:
Key Features:
