Instruments of various sizes used to measure the amount of ultraviolet and visible light absorbed by a sample. Product applications include quality control, nucleic acid/protein quantification, analysis of sample purity, and classroom learning.

Instruments that determine the infrared spectrum of absorption or emission of solid, liquid, or gas samples. IR spectra reveal sample composition and are used in the identification of unknown materials and confirmation of production materials.

Devices, kits, reagents, and accessories for analyzing fluorescence or fluorescence polarization. Fluorometers identify the presence/amount of specific molecules in a sample, and fluorescence polarization systems monitor binding events in solution.
