Fractionating Column (vigrux)

What is it?

A Fractionating Column (Vigreux) is a laboratory glassware component used to improve the separation of liquid mixtures during fractional distillation. Manufactured from high-quality borosilicate glass, the column features a series of inward-pointing glass indentations that provide repeated vapor-liquid contact inside the column. This increases the effective surface area for condensation and revaporization, enabling more efficient separation of components with different boiling points.

Key Features and Benefits

• Premium Borosilicate 3.3 Glass: Manufactured from chemically resistant borosilicate glass, providing excellent resistance to heat and commonly used laboratory chemicals.
• Vigreux Indentations: Internal glass projections increase vapor-liquid contact and promote repeated condensation and vaporization for improved fractional separation.
• Efficient Distillation: Designed to improve the separation of liquid mixtures having relatively close boiling points compared with simple distillation.
• Uniform Construction: Precisely formed column geometry provides consistent performance and reliable operation during laboratory distillation procedures.
• Excellent Thermal Resistance: Suitable for controlled heating applications and repeated laboratory distillation cycles when used under appropriate operating conditions.
• Easy Integration: Available with standard ground-glass joints for convenient connection with distillation flasks, condensers, adapters, and other compatible laboratory apparatus.

Available Sizes

Fractionating Columns are available in various lengths and joint configurations to suit different laboratory distillation assemblies. Custom dimensions, capacities, and ground-glass joint specifications can be provided on request.

Applications

Widely used in chemistry laboratories, pharmaceutical research, petrochemical laboratories, educational institutions, and quality-control facilities for fractional distillation, purification of liquid mixtures, solvent recovery, and separation of components based on differences in boiling points.

Quality Commitment: Every Vigreux Fractionating Column is manufactured from high-quality borosilicate glass and carefully inspected for dimensional accuracy, smooth finish, and reliable ground-glass joint compatibility to ensure consistent performance in laboratory distillation applications.
