Product Description

The LABMAN LMSPUV1920 (single 10 mm cell holder) and LMSPUV1928 (8-cell holder) are double beam UV-Vis spectrophotometers covering 190–1100 nm with a variable 1, 2 or 4 nm bandwidth, a 520 mm long light path, ±0.3 nm wavelength accuracy and a 6 inch LCD that shows results and curves directly. Two detectors measure sample and reference simultaneously for better accuracy.

Key features

  • Free onsite installation
  • Double beam design with two detectors measuring sample and reference simultaneously
  • Unique 520 mm long light path for improved resolution
  • 16 mm rigid die-cast aluminium optical base
  • 6 inch LCD showing results and curves on the instrument
  • On-instrument functions: wavelength scanning, standard curve, kinetics, multi-wavelength scanning, DNA / protein test
  • Automatic calibration of baseline, wavelength and dark current
  • Lamp selection to extend D2 and tungsten lamp life; real-time clock stamps results; USB port to PC
