KIMBLE® FLEX-COLUMN® chromatography columns are economical and easy-to-use. Short columns are typically used for ion exchange chromatography, sample desalting and semi-disposable applications, while the long columns are ideally suited for gel filtration and adsorption chromatography.

Columns are constructed of polypropylene reservoirs and column outlets permanently connected to a borosilicate glass barrel. Barrels are manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements. Bed support is manufactured from High Density Polyethylene (HDPE) with 20-micron nominal bed support porosity. Sterilize with 2N NaOH or 100% ethanol, autoclaving is not recommended.
