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.
** We cannot ship rental units out of the US **
You can pay online but call us to reserve your unit and to tell us when you want it to arrive.
