Project Description


Programmable UV-VIS spectrometer for reliable analyses in research and industry

The basic programmable UV-VIS spectrometer for routine operation

Our new programmable UV-VIS spectrometer M508 is designed for easy routine operation with focus on high robustness. The manual spectrometer has a wavelength range of 200-1000 nm and a spectral bandwidth of 4 nm with low stray light (<0.1 %T at 220 nm & 340 nm).
It has a four-line LCD display with 20 characters, a keypad with nine keys and stepper motors for wavelength and filters.
It allows storage of up to 200 methods for extensive analysis projects.

Some of the functions of the M508 at a glance:

  • Stores up to two hundred methods/results
  • Concentration calibration with up to eight standards and up to three repeats
  • Selectable wavelength calibration and dark current measurement
  • Wavelength range 200 – 1000nm
  • bandwidth 4nm
  • Low stray light (<0.1%T at 220 nm and 340 nm)
  • Large sample compartment (for cuvettes up to 100 mm path length)
  • Manual 4-cell changer & four 10mm glass cells included
  • Wide range of accessories
  • Optional software for wavelength scan, concentration curves, DNA/protein measurements, kinetics mode and multi-wavelength test
