Description
Chromatography column with packing height approximately 750 mm, inner diameter 70 mm, socket NS 45/40 and frit porosity 0 is a laboratory glass column intended for preparative and analytical chromatography. Made from borosilicate glass 3.3, it features a PTFE stopcock with NS 14,5 joint and 2,5 mm bore plus a glass filter plate of porosity 0 that keeps dead volume low. The outer diameter measures 80 mm while the ground joint is NS 45/40, ensuring compatibility with standard laboratory glassware. This column from manufacturer Rettberg supports clean separations and reproducible packing beds. Filling height can be customised upon request to match individual method needs. Supplied as one piece, the column is well suited to organic synthesis, natural-product isolation and pharmaceutical purification workflows. The chemical resistance and mechanical stability of borosilicate glass 3.3 allow repeated use with common laboratory solvents and stationary phases under typical operating conditions.
