Fractionating Column, Vigreux
Strategically Aligned Internal Indentations: Features a series of precision-formed glass spikes that significantly increase the effective surface area for repeated condensation and re-evaporation cycles.
CNC-Ground Standard Taper Interfaces: Manufactured with a 1:10 taper ratio and a high-vacuum matte finish, ensuring a hermetic, leak-proof seal across all standardized modular glassware configurations.

Quick answer: A Vigreux Fractionating Column uses internal glass indentations to increase vapor-liquid contact during fractional distillation, allowing more precise separation of liquid mixtures by boiling point without needing loose packing material. Fractionating Column, Vigreux is priced at approximately ₹245 (indicative market benchmark, incl. GST, August 2026).
The Vigreux column’s specialised internal indentations increase the surface area for vapor-liquid contact as vapor rises through the column, improving separation efficiency for liquids with different boiling points compared with a plain fractionating column. Because the indentations are fused into the glass itself, no separate packing material is needed, which simplifies cleaning between uses. Fractional distillation using a Vigreux column is a standard technique taught in organic chemistry coursework for separating mixtures of liquids with close boiling points, and is also used in research-scale purification work.

Applications
- Fractional distillation of liquid mixtures with close boiling points
- Teaching fractional distillation principles in organic chemistry coursework
- Research-scale purification requiring efficient vapor-liquid contact
- Replacing a plain distillation column where finer separation is needed
Care & Maintenance
- Clean thoroughly between distillations to prevent residue on the internal indentations
- Handle carefully, since the internal indentations are more delicate than a plain column’s smooth bore
- Check ground glass joints for a tight fit before each use

Frequently Asked Questions
How does a Vigreux column improve distillation?
Its internal indentations increase the surface area for vapor-liquid contact as vapor rises, improving separation of liquids with different boiling points compared with a plain column.
Does this column need packing material?
No — the fused internal indentations provide the increased surface area directly, so no separate packing material is required.
What length and joint size is this column?
Exact length and joint size have not been independently verified for this listing — confirm compatibility with your existing glassware with STEMAids before ordering.
Is this suitable for a college organic chemistry lab?
Yes — Vigreux columns are standard equipment for teaching and performing fractional distillation in organic chemistry coursework.
Can this column be used for research-scale purification?
Yes, in addition to teaching use, Vigreux columns are commonly used in research-scale distillation and purification work.
Is STEMAids a registered manufacturer of this product?
Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
