S.C. Glass Instruments Chromatography Column 40mm Dia 10in Borosilicate Lab

S.C. Glass Instruments Chromatography Column 40mm Dia 10in Borosilicate Lab

This is a glass chromatography column made by S.C. Glass Instruments of Bonita, California. The column measures 40mm in inner diameter and approximately 10 inches in usable length, with a clear borosilicate glass body and a side-exit outlet stem at the bottom end. The open top serves as a solvent reservoir for loading sample and mobile phase.

Applications

Glass chromatography columns like this are standard equipment in chemistry, biochemistry, and pharmaceutical laboratories for separating mixtures by gravity or low-pressure flow. A 40mm bore column is a mid-to-large diameter size suited to preparative-scale separations — isolating a target compound from a reaction mixture, purifying natural product extracts, or fractionating polymer samples — where a larger bed volume is needed compared to analytical-scale columns. S.C. Glass Instruments was a U.S. maker of precision laboratory glassware; their columns are well regarded for consistent bore dimensions and quality glass. This size is commonly used with silica gel, alumina, or other stationary phases packed directly into the column, with the side-exit stem connected to a collection vessel or fraction collector.
