Q-8 Double Beam UV-Vis Spectrophotometer

Q-8 Double Beam UV-Vis Spectrophotometer

Instrument Features and Functions

  • Hybrid C-T double monochromator optical system with selected high-quality components achieves high resolution and ultra-low stray light of less than 0.00005%T, ensuring high-sensitivity determination across the entire detection wavelength range.
  • Continuously adjustable spectral bandwidth from 0.1nm to 5.0nm in 0.1nm increments.
  • 185nm~900nm (expandable spectrum) scanning range, paired with an original imported photomultiplier tube for sensitive response in short-wave scanning.
  • Independent modular design with socket-type deuterium and tungsten lamp units for easier instrument maintenance.
  • Strong instrument expandability with optional accessories like an optical integrating sphere, multifunctional autosampler, automatic multi-cell holder, specular reflection accessory, constant temperature cell holder, variable angle solid sample holder, and variable pathlength sample holder to meet multi-dimensional testing needs.
  • The shell is made with a precision injection molding process, featuring smoother lines and ensuring durability.
  • High degree of automation; the multifunctional autosampler allows users to achieve automated control and operation.
  • Professional analysis software for photometric measurement, quantitative measurement, spectral scanning, kinetic analysis, DNA/protein testing, etc., with powerful data processing capabilities.
  • The software complies with GLP/GMP regulations, facilitating user management, log recording, and data tracking functions.
