Solvents are a class of chemicals defined by their function. Solvents are used to dissolve, suspend or extract other materials without chemically changing the components.

There are more than 1000 solvent varieties used in research, spectroscopy, analytical chemistry and manufacturing industries. They come in Research, Technical, USP, HPLC, LCMS, ACS Reagent, ASTM Types 1-IV, NIST Traceable, and Spectral grades, as well as molecular biology grades and pre-made mixtures as DNAse-free solutions.
