#R1 Spectrophotometer Rental — CHEMUSB4 UV-VIS Absorbance




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

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!

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

You can pay online but call us to reserve your unit and to tell us when you want it to arrive.
