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.

CarboBlack columns (packed)

CarboBlack columns (packed)

Supplier: Restek

Graphitised carbon black offers unique selectivity and very little adsorption for alcohol analyses. Two types of CarboBlack supports are available, CarboBlack B and CarboBlack C. CarboBlack B support, with its higher surface area, can hold up to a 10% loading of a non silicone liquid phase. CarboBlack C support can hold up to a 1% loading of a non silicone liquid phase.
