UV Open Colorimeter

The UV Open Colorimeter is a single-wavelength photometer for measuring UV light absorbance through samples in a standard 10mm pathlength cuvette. Applications include protein quantification with a UV LED. 

The device uses our AS7311 UV sensor board and a PyBadge pre-programmed with open source CircuitPython firmware. The cuvette holder and enclosure are made from 3D-printed black plastic. Links to the hardware designs and open source firmware and libraries are in the Product Guide.

The UV Open Colorimeter ships pre-programmed & ready-to-use. No assembly, soldering or programming is required. It can be powered by USB or a 3.7V lithium ion battery.  Battery is not included. See the Product Guide for battery recommendations.
