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.
Highlight:
◊ Variable bandpass options: 0.5, 1.0, 1.5, 2.0 or 4.0 nm over the range 190 nm – 1100 nm
◊ Fast scanning: up to 6,000 nm/min to aid sample analysis throughput
◊ Automatic accessory recognition: when connected to the DB30
◊ Optional Visacle® software: for easy PC control
◊ Touchscreen interface: intuitive menus and functions for ease of use for standalone control
◊ Multiple Data Storage Options: USB, SD card and internal data storage for convenient retrieval of methods and results
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.
Software:
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:
◊ Configurable user profiles with secure login and e-signatures
◊ Audit trail logging of all actions taken
◊ Permission system to restrict actions and data access to authorised users
