Synthware Chromatography Column 24/40 with PTFE Stopcock and Coarse Fritted Disk 305 mm Length 44 mm ID

Synthware C184463C Chromatography Column. This preparative-scale glass laboratory column is engineered for the efficient separation and purification of organic compounds utilizing gravity or low-pressure flash chromatography techniques. It features an integrated fritted glass support and a precision PTFE stopcock to deliver exact solvent flow control while maintaining a completely grease-free, high-purity fluid path.

• MPN / Catalog Model: C184463C (often listed under the Synthware general chromatography catalog).
• Manufacturer & Line: Synthware (manufactured and distributed by Kemtech America).
• Quantity & Packaging / Form Factor: Single unit. The main cylindrical body features an effective stationary phase packing length of 305 mm and an internal diameter (I.D.) of 44 mm.
• Material Construction / Metallurgy: Fabricated from high-expansion, chemical-resistant borosilicate glass. The assembly includes a sealed-in coarse porosity glass fritted disk and a chemically inert, self-lubricating PTFE (Teflon) stopcock plug.
• Technical Specifications & Tolerances: Terminated with a 24/40 Standard Taper (ST) top outer joint. The coarse frit provides robust mechanical support for standard silica gel or alumina stationary phases while permitting unobstructed mobile phase flow, entirely eliminating the need for manual glass wool plugs.
• Hardware & System Compatibility: The 24/40 top joint seamlessly accepts standard 24/40 inner joint solvent reservoirs, pressure/flash adapters, addition funnels, or glass stoppers. The external glass body is designed to mount securely to standard laboratory grid networks or ring stands using conventional heavy-duty chain or three-prong clamps.
• Standards, Cleanliness & Purity: Borosilicate glass ensures maximum resilience against harsh organic solvents and rapid thermal changes. The PTFE stopcock enables completely grease-free solvent elution, preserving the extreme purity of highly sensitive isolated analytical fractions and preventing joint seizure.
• Primary Application: Preparative-scale column chromatography, flash chromatography, and the bulk bulk purification, isolation, and separation of complex organic reaction mixtures in synthetic chemistry workflows.
