Vous avez recherché : Chromatography Columns
Chromatography columns separate molecules within mixtures during gas or liquid methods. Filled with stationary phase compositions or resins, the prepacked options reduce the preparing time required. The vertical pieces are able to withstand extreme temperatures and pressure fluctuations experienced when the mobile phase is forced through the medium. Meet preparative and analytical laboratory procedures with the chromatography columns to separate dissimilar moving components based on individual polarity, composition, and size.
