Absorbance Spectrophotometry

Our CHEM4-series Spectrophotometers for education are small-footprint, PC-based systems designed for chemistry professors, teachers and others who use spectroscopy as a teaching tool.
These fully integrated systems - including spectrometer, light source, cuvette holder - are available at dramatic discounts with the trade-in of an old lab instrument. Acquire and display data - 3648 wavelengths - in <1 second with our convenient PC-based systems.

The CHEMUSB4-UV-VIS has a state-of-the-art, miniature RF-excited deuterium tungsten source. The CHEMUSB4-VIS has a direct-attach combination tungsten and blue LED source. You can separate each spectrometer from its integrated light source to couple the spectrometer to any of our fibre optic accessories and light sources.

The CHEM4-UV-FIBER and CHEM4-VIS-FIBER include a light source and cuvette assembly that attaches to the spectrometer with an optical fiber. The advantage of this design is that the light source can be easily coupled to other fibre optic accessories such as reflection probes or transmission dip probes. The CHEM4-VIS-FIBER comes with a tungsten source and the CHEM4-UV-FIBER uses a deuterium tungsten source.
