Condenser, Allihn
High-Efficiency Bulbous Geometry: Engineered with a series of expanded glass bulbs that significantly increase the internal surface area compared to standard Liebig designs, optimizing vapor-liquid contact time and preventing "choking" during high-velocity reflux.
Precision-Ground Tapered Joints: Equipped with standardized interchangeable glass joints that undergo micro-tolerance grinding to ensure vacuum-tight, hermetic seals within complex distillation manifolds and modular laboratory glass assemblies.

Quick answer: An Allihn Condenser has a bulbous inner tube that increases the surface area for cooling, making it especially efficient for reflux applications where vapor needs to be condensed continuously. Condenser, Allihn is priced at approximately ₹375 (indicative market benchmark, incl. GST, August 2026).
An Allihn condenser has a series of bulbs along its inner tube, rather than a plain straight tube, which increases the surface area in contact with the vapor as it rises. That extra surface area gives more efficient cooling and condensation, making the Allihn condenser especially well suited to reflux setups where vapor needs to be condensed and returned to the flask continuously over an extended period. It’s a standard piece of equipment for reflux and organic synthesis practicals in college and research chemistry laboratories.

Frequently Asked Questions
What is an Allihn condenser used for?
It’s designed for efficient vapor condensation, especially in reflux setups, using a bulbous inner tube that increases the cooling surface area.
What length and joint size does this condenser have?
These have not been independently verified for this listing — confirm with STEMAids before ordering.
How does this differ from a Liebig condenser?
The Allihn condenser’s bulbous inner tube gives more surface area for cooling than the Liebig’s plain straight tube, making it more efficient for continuous reflux applications.
Is this suitable for a college organic chemistry lab?
Yes — Allihn condensers are standard equipment for reflux practicals common in organic chemistry coursework.
Does STEMAids supply matching flasks and heating equipment for reflux setups?
Contact STEMAids to confirm compatible components for a complete reflux setup.
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.
