UV-Vis spectrophotometer DB30

double-beamhalogentungsten halogen

The DB30 UV-Vis Spectrophotometer is a powerful double beam instrument designed for precise and accurate measurement of absorption and transmission across various wavelengths, making it essential for analytical applications where precision is paramount. Engineered for versatility, this user-friendly spectrophotometer excels in a wide range of measurements, from standard absorbance in cuvettes to solid samples and flow cell experiments. Its high-throughput optical design delivers exceptional performance, ensuring superior stray light control, baseline stability, and unmatched wavelength and photometric accuracy. The DB30 offers flexible operation, whether as a standalone device with its integrated touchscreen or through PC control using Visacle® software. Visacle provides a secure database for storing data and methods, and it can be upgraded to a CFR Part 11 compliant package for enhanced data protection and integrity.
