CHEMUSB4 UV-VIS for RENT – Absorbance Spectrophotometer #R1




The CHEMUSB4-UV-VIS is a very fast UV-VIS spectrophotometer, providing complete scans in milliseconds, reliable, high resolution UV-VIS spectrophotometer that plugs into the USB port of your computer.

  • Rental credits! – 50% of rents paid can be applied towards the purchase of a new system (up to 50% of the sale price).

The wavelength range is 200-850nm. Resolution is ~1.5nm FWHM.  The light source/cuvette holder works with standard 1cm cuvettes (OD 12.5 x 12.5mm) including quartz and polymer (disposable) types. Some plastic cuvettes are included. If you need quartz cuvettes add those to your order!

  • 200-850nm, 1.5nm FWHM optical resolution, 0.3nm pixel resolution
  • 1cm cuvette holder with integrated deuterium/tungsten light source
  • Oceanview software provides absorbance, transmission, CIE color, Beers Law etc. Use the 10 day free trial or purchase Oceanview for longer rental periods.
  • we sell a complete line of quartz, glass and plastic cuvettes

Rent is by the week or month, starting with the day you receive it until the day you ship it back.
