Project Description


Programmable VIS spectrometer for reliable analyses in research and industry

The basic programmable VIS spectrometer for routine operation

Our new programmable VIS spectrometer M108 is designed for easy routine operation with focus on high robustness. The manual spectrometer has a wavelength range of 325-1000 nm and a spectral bandwidth of 4 nm with low stray light (0.1 %T at 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 M108 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 325 – 1000nm
  • bandwidth 4nm
  • Low stray light (0.1%T at 340nm)
  • 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
