Versatile double beam UV-Vis spectrophotometer with a benchtop footprint. Suitable for analytical, research, and pharmaceutical industry applications.
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.
As standard, the DB30 comes with a touchscreen for standalone operation controlling all modes of operation: photometry, time scan, wavelength scan, and data analysis, including calibration curves.
Additionally, Visacle® PC-controlled software enhances your DB30 experience by offering comprehensive control, validation, data analysis, and reporting—all in one streamlined package. With Visacle, your data is securely stored in an organised database, ready for analysis and easy export in .txt, .csv, or PDF formats.
For those needing extra security, Visacle is available as a CFR Part 11 compliant package. Key features include:
Core Features
UV Absorption Spectra
The DB30 covers the UV range down to 190 nm with an absorbance range > 3.
This makes measuring samples high UV absorption possible, such as the edible oil spectra plotted below.
UV absorption spectra of heat-treated extra virgin olive oil, blended oil, virgin olive oil, extra virgin olive oil, and pomace oil; measured in a standard DB30 dual spectrophotometer.
