Double Beam UV-VIS Spectrophotometer

About Double Beam UV-VIS Spectrophotometer

The Lasany Microprocessor UV-VIS Double Beam Spectrophotometer (LI-2802 R) is a high-precision analytical instrument designed for quantitative and qualitative laboratory analysis. It utilizes a double-beam optical system to simultaneously measure sample and reference beams, which compensates for light source fluctuations and ensures long-term stability

Key Features

• Double Beam Optics: Features a blazed holographic grating (1200 lines/mm) and dual silicon photodiode detectors for enhanced accuracy and reduced drift.
• Sample Handling: Equipped with an automatic 8-cell holder for 10mm pathlength cuvettes, significantly increasing sample throughput.
• Operating Modes: Supports diverse measurement methods including Basic Mode, Quantitative (standard curve), Kinetics, Multi-wavelength, Wavelength Scan, and DNA/Protein testing.
• Automated Calibration: Features automatic wavelength calibration, system self-testing, and automatic lamp change-over between Deuterium and Tungsten lamps.
• 21 CFR Part 11 Software (Optional): While standard software is included, compliance software for pharmaceutical GLP/GMP requirements (21 CFR Part 11) is available at an extra cost to provide electronic audit trails and secure user access.
