Chromatography Column with PTFE Stopcock – Precise Separation Technology for Laboratory and Research

High-quality chromatography columns made of borosilicate glass 3.3 for analytical and preparative chromatographic separation processes. The columns are equipped with a precise PTFE stopcock (2.5 mm bore) and available with either integrated frits of various porosities or with indentations.

Technical Features:

• Filling heights: 200 mm, 500 mm, 750 mm, 1000 mm
• Diameters: 10 mm, 15 mm, 20 mm, 30 mm, 60 mm, 70 mm, 80 mm, 90 mm
• Ground joints: NS 14,5/25, NS 29/32, NS 45/40 (depending on model)
• Versions: With frit (Por. 0, Por. 1, Por. 2, Por. 3) or with indentations
• PTFE stopcock with 2.5 mm bore
• Material: Borosilicate glass 3.3
• With evaporation stopcock for vacuum applications (selected variants)

Product Properties:

• Chemically resistant to most solvents
• Thermally stable
• Optimum transparency for observation of separation process
• Precise flow control through PTFE stopcock
• Flexible choice between frit and indentations depending on application

Applications: Column chromatography in organic chemistry, natural product chemistry, pharmaceutical research and analytics. Suitable for flash chromatography, routine separations and preparative isolations in laboratory and research operations.

Variant Selection: The chromatography columns are available in various combinations of filling height, inner diameter, ground joint and version (frit or indentations) to ensure optimum adaptation to specific separation tasks.
