Quick answer: This Two/Three-Neck Boiling Flask lets multiple instruments — such as a thermometer, condenser, and stirring rod — be fitted at once, supporting more complex distillation and synthesis setups than a single-neck flask. Flask, Boiling, Two/Three Neck (Round/Flat Bottom) is priced at approximately ₹750 (indicative market benchmark, incl. GST, August 2026).
This multi-neck boiling flask has two or three ground-glass necks, allowing several pieces of equipment to be connected to the flask at the same time — for example, a condenser on the main neck with a thermometer and a dropping funnel or stirring rod on the side necks. That lets a more complex reaction or distillation be monitored and controlled simultaneously, rather than needing separate setups. Available in round or flat-bottom configurations, it’s suited to multi-stage reactions and controlled synthesis work in college and research chemistry laboratories.

Applications
- Multi-stage synthesis reactions requiring simultaneous instrumentation
- Distillation setups needing a thermometer and condenser fitted together
- College and research chemistry laboratory advanced practicals
- General-purpose complex glassware assembly
Care & Maintenance
- Grease each ground-glass joint lightly to maintain a reliable seal at every neck
- Handle carefully — multiple necks create more fragile points on the flask
- Clean thoroughly after each use to prevent residue buildup at each joint
