Features:
High-Class Grating and Hermetic Light Path Design: Ensures ultra-low stray light, providing accurate and precise measurements by minimizing light interference.
SiO₂ Coating Optical Mirror: Effectively reduces external pollution, maintaining the performance and accuracy of the instrument by protecting against contamination.
Real-Time Lamp Lifetime Monitoring: Continuously monitors the lifespan of Deuterium and Tungsten lamps, alerting users when a replacement is needed to ensure consistent performance.
Automatic Wavelength Calibration and Dark Current Calibration: Automatically calibrates wavelength settings, changes the lamp source, and adjusts for dark current, ensuring accurate and reliable results.
GLP Self-Check Function: Performs self-checks on wavelength and photometry accuracy, ensuring compliance with Good Laboratory Practice (GLP) and maintaining measurement consistency.
Comprehensive analysis capabilities: supports photometry, quantitative analysis, kinetics, multi-wavelength testing (up to 8), scanning (190-1100nm), and DNA/protein analysis with curve storage.
