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. Comes with several polymer cuvettes (230-900nm). You can purchase quartz cuvettes (200-2500nm) or a box of disposable cuvettes to your order.
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 on this CHEMUSB4 UV-VIS spectrophotometer rental 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!
