Amersham Biosciences AKTA UV-900 Variable Wavelength UV-Vis Detector for Liquid Chromatography
Product Description
The Amersham Biosciences AKTA UV-900 Detector is a high-precision UV absorption monitor designed for liquid chromatography systems. It supports a variable wavelength detection range from 190 to 700 nm and allows simultaneous monitoring of up to three wavelengths, enabling detailed analysis of complex biomolecules and chromatographic separations common in biotechnology and molecular diagnostics.
Key technical features include:
- Two interchangeable flow cells with path lengths of 2 mm and 10 mm to optimize sensitivity and dynamic range.
- Advanced self-test and self-calibration functions enhance reliability and accuracy in chromatographic detection.
- Utilizes fiber optic technology to ensure stable and noise-reduced signal measurements.
This UV-Vis detector is widely adopted in bioprocessing workflows, particularly in protein purification, gene editing analysis, and synthetic biology research where precise, multi-wavelength UV detection is critical. Its performance supports applications across biomedical engineering and molecular cloning workflows, making it essential for researchers requiring dependable UV monitoring in complex liquid chromatography assays.
