CHROMATOGRAPHY COLUMN

Chromatography Glass Column with PTFE Stopcock (Tap)

Product Overview:
A precision borosilicate glass chromatography column designed for gravity or low-pressure separations. Equipped with a chemically inert PTFE stopcock for accurate flow control, this column is suitable for analytical and preparative chromatography applications in laboratories.

Key Properties:
High-transparency borosilicate glass construction
Integrated PTFE stopcock (chemically resistant, leak-proof)
Uniform internal diameter for consistent packing and flow
Smooth inner wall to minimize adsorption losses
Straight cylindrical design with reinforced joints

Description:
This chromatography column is engineered for efficient separation of compounds using stationary phase packing such as silica gel, alumina, or resin media. The PTFE tap ensures precise regulation of eluent flow without contamination or degradation from solvents. Suitable for organic synthesis labs, research institutions, and quality control environments.

Handling & Storage:
Handle with care to avoid mechanical shock
Store upright in padded racks or protective packaging
Clean thoroughly after each use to prevent cross-contamination
Avoid sudden temperature changes (thermal shock risk)

Hazard Information:
Fragile glassware – breakage may cause injury
PTFE components are inert but should not be exposed to open flame
Use appropriate PPE (gloves, goggles) during operation.

Packaging:
Individually packed with protective foam or bubble wrap
Bulk packaging available for institutional orders

Safety Note:
Always ensure proper column support during use. Do not overtighten or force the PTFE stopcock. Verify compatibility of solvents with PTFE and glass before operation.
