PYREX® Chromatography Column with Coarse Fritted Disc and PTFE Stopcock

The PYREX® Chromatography Column with Coarse Fritted Disc and PTFE Stopcock is a precision laboratory glass column designed for chromatographic separation, sample purification and chemical analysis. It features a permanently sealed coarse-porosity fritted glass disc and a chemically resistant PTFE stopcock for controlled solvent flow. Its design minimises liquid mixing below the fritted disc, helping maintain clear separation bands and improve fraction collection. Key Features - Premium PYREX® Glass: Durable laboratory glass construction suitable for chromatographic applications. - Column Dimensions: Approximately 10 mm internal diameter × 300 mm length. - Coarse Fritted Disc: Integrated glass disc with 40–60 µm porosity. - PTFE Stopcock: Chemically resistant polytetrafluoroethylene stopcock for controlled liquid flow. - Stopcock Plug Size: No. 2 plug for precise flow adjustment. - Efficient Separation: Reduced space below the fritted disc helps minimise solvent mixing. - Rubber Stopper Compatibility: Designed for a No. 00 rubber stopper. - Laboratory Applications: Suitable for chromatographic analysis, chemical separation and sample purification.
