A true, high accuracy, double beam UV/Visible range instrument with variable 0.5, 1, 2, 4 and 5nm spectral bandwidths, using either the integrated controller or remotely by the user’s PC via Windows® compatible Prism PC software supplied.

  • Six measurement modes:
    • — Photometrics and multi-wavelength spectrum scanning (up to 10 wavelengths can be measured, or 20 using Prism PC software, with up to 0.1nm resolution and 2000nm/min. scan speed)
    • — Spectrum scanning (up to 0.1nm resolution and 2000nm/min. speed)
    • — Kinetics (up to 12 hours with time intervals of 0.1, 0.2, 0.5, 1, 2, 5, 10 or 30 seconds)
    • — Quantitation (up to 3 wavelength points using up to 10 standards)
    • — DNA/RNA (ratio, concentration, A320 correction)
    • — Protein analysis (autopeaks and valleys, zoom, addition, subtraction, peak ratios, smoothing, area under curve, wavelength table, derivatives and overlay with PC software)
  • Range: 190 to 1100nm
  • Prism PC software is designed to give a comprehensive range of measurement modes whilst remaining intuitive, user-friendly and providing extensive post-measurement tools and functions
  • Large graphical display
  • Conforms to European Pharmacopoeia standards
  • Range of interchangeable sample chambers allows rapid reconfiguration or upgrade
  • Units with IQ/OQ documentation are available - details on request

Supplied with single 10 x 10mm cuvette holder (sample and reference positions), instruction manual, Prism PC software with USB cable, 2 quartz and 4 glass cuvettes and dust cover. For 230V 50/60Hz single phase supplies.
