7” Polypropylene Disposable Gravity Column

Polypropylene columns are contact-transparent, more chemically-resistant and appropriate for use with organic solvents and stronger acids (except oxidizing acids) and alkalis. These columns are for use in general chromatographic work for extraction of components, with special applications in isoenzyme and protein studies, hemoglobin fractionation and desalting. Chromatography columns are precision-molded in 5 ̋ sizes from premium-grade, chemically inert plastics.
