Description
This used Thermo Scientific Evolution 300 BB UV-Vis Spectrophotometer with VISIONsecurity Software is a high-performance double-beam UV-Visible spectrophotometer designed for accurate absorbance, transmittance, reflectance and concentration measurements. The system is suitable for pharmaceutical laboratories, quality control, life science research, biochemical analysis, material science, environmental testing and general analytical laboratory applications.
The Evolution 300 platform combines a stable double-beam optical design with a xenon flash lamp, dual matched silicon photodiode detectors and variable spectral bandwidth. It can be operated through Thermo Scientific VISION software, providing advanced data acquisition, analysis and reporting functions. The included VISIONsecurity software is especially useful for regulated laboratory environments, offering security and compliance-related tools for controlled access, audit trails and electronic records.
This system is supplied with a PC, monitor, keyboard and mouse, VISIONsecurity and Visionlife software and sample accessories as pictured. The instrument has been tested with a Thermo Scientific UV Validator kit, including a holmium scan shown in the supplied photos. The system has been tested and is in good condition.
