Flask, Retort (Stoppered)

Quick answer: A Stoppered Retort Flask has a pear-shaped body and a downward-sloping neck, designed for distilling liquids or dry-distilling solids, with the sloped neck guiding vapor to a collection point. Flask, Retort (Stoppered) is priced at approximately ₹650 (indicative market benchmark, incl. GST, August 2026).

A retort flask has a traditional pear-shaped body with a long, downward-sloping neck. When a liquid is heated in the body, vapor rises and travels down the sloped neck to condense and be collected, making it suited to simple atmospheric distillation. It’s also used for dry distillation, where a solid is heated to decompose and release vapors that condense along the neck. The stoppered version allows the flask body to be sealed during heating. Made for laboratory use, it’s a traditional but still-useful piece of equipment in college and research chemistry laboratories.

Technical Specifications

Applications

• Simple atmospheric distillation of liquids
• Dry distillation of solids
• College and research chemistry laboratory demonstrations of classical distillation technique
• General-purpose heated containment with vapor collection

Care & Maintenance

• Use appropriate heating equipment and heat gradually to avoid thermal shock
• Handle carefully — the sloped neck is a fragile point on the flask
• Clean thoroughly after each use to prevent residue buildup
