Thistle Funnel, Clear Glass
Fire-Polished Stem Terminus: Features a precision-annealed, fire-polished tip that ensures smooth liquid discharge and resists chipping during insertion through rubber stoppers or tight-fitting laboratory bungs.
Standardized Reservoir Geometry: Engineered with a uniform wall distribution throughout the thistle-head, providing enhanced mechanical strength to withstand the lateral pressure of routine manual laboratory handling.

Quick answer: This Clear Glass Thistle Funnel allows controlled addition of liquids into narrow-necked vessels, commonly used in gas evolution setups to maintain a liquid seal while adding reagents. Thistle Funnel, Clear Glass is priced at approximately ₹258 (indicative market benchmark, incl. GST, August 2026).
A thistle funnel has a bulb-shaped top and a long, narrow stem, designed to be inserted through a stopper into a reaction flask for the controlled addition of a liquid reagent. Its long stem extends below the liquid level in the flask, maintaining a liquid seal that lets reagent be added drop by drop without letting gas escape back up the funnel — useful in gas evolution reactions. Made from clear glass, it provides good optical clarity for monitoring flow, and is a standard piece of equipment in college and school chemistry teaching laboratories.

Applications
- Controlled addition of liquid reagents in gas evolution reactions
- Maintaining a liquid seal in stoppered reaction flasks
- College and school chemistry teaching laboratories
- General-purpose liquid addition into narrow-necked vessels
Care & Maintenance
- Handle carefully — clear glass is more prone to thermal shock than borosilicate
- Clean thoroughly after each use to prevent residue buildup in the narrow stem
- Avoid using with hot reagents or near open flames given the lower heat resistance
