Fractionating Column, Rod and Disk Pattern

Quick answer: The Rod and Disk Pattern Fractionating Column uses an internal disk geometry to increase vapor-liquid contact, supporting precise fractional distillation of liquid mixtures with narrow boiling point ranges. Fractionating Column, Rod and Disk Pattern is priced at approximately ₹230 (indicative market benchmark, incl. GST, August 2026).

This fractionating column’s internal rod-and-disk structure increases the surface area available for vapor-liquid contact as vapor rises, improving separation efficiency for mixtures with narrow, closely spaced boiling points compared with a plain column. It fits into a modular glass distillation assembly and is a standard piece of apparatus for teaching and performing fractional distillation in organic and analytical chemistry coursework, as well as for research-scale separation work where higher-resolution separation than a plain column offers is needed.

Technical Specifications

Applications

• Fractional distillation of liquid mixtures with narrow, closely spaced boiling points
• Teaching fractional distillation principles in organic and analytical chemistry coursework
• Research-scale separation requiring higher resolution than a plain column
• Replacing a plain fractionating column where finer separation is needed

Care & Maintenance

• Clean thoroughly between distillations to prevent residue on the internal disks
• Handle carefully, since the internal rod-and-disk structure is more delicate than a plain column
• Check ground glass joints for a tight fit before each use

Frequently Asked Questions

How does the rod-and-disk design improve distillation?

The internal disk geometry increases the surface area for vapor-liquid contact as vapor rises through the column, improving separation of mixtures with closely spaced boiling points.

Is this suitable for a college organic chemistry lab?

Yes — rod-and-disk fractionating columns are used for both teaching and research-level fractional distillation in organic and analytical chemistry coursework.

What length and joint size does this column have?

Exact length and joint size have not been independently verified for this listing — confirm compatibility with your existing glassware with STEMAids before ordering.

How does this compare with a plain fractionating column?

The rod-and-disk design generally offers finer separation for mixtures with narrow boiling point ranges compared with a plain column, at the cost of being more delicate to handle.

Does STEMAids supply this for bulk institutional orders?

Yes — contact STEMAids to confirm current quantities and indicative pricing for institutional or bulk orders.

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.
