Professional Grade Sample Purification

Our Plain Chromatography Column is engineered for high-resolution separation of chemical mixtures. Featuring a precision-ground glass stopcock, this column offers manual control over flow rates (elution), making it ideal for standard laboratory purification tasks and educational chemistry demonstrations.

The "plain" top design allows for easy sample loading and is compatible with standard lab stoppers or flexible tubing connections for gravity-fed solvent delivery.

Key Technical Features

• Premium Borosilicate 3.3 Glass: Exceptional chemical resistance to aggressive solvents, acids, and bases.
• Precision Glass Stopcock: Hand-ground for a leak-proof seal and smooth rotational control without the need for high-pressure fittings.
• Heavy-Wall Construction: Designed for durability and thermal stability during exothermic adsorption processes.
• Uniform Internal Diameter: Ensures a consistent "plug flow" and prevents band broadening during separation.

Primary Applications

• Column Chromatography: Separation of organic compounds based on differential adsorption.
• Sample Clean-up: Removal of impurities from synthesized products before analysis.
• Fractional Collection: Precise manual dripping for gathering individual chemical fractions.
