Quick answer: This Three-Neck Adapter fits onto a single-neck flask to provide three access points — two parallel vertical sockets and one angled socket — supporting simultaneous reagent addition, temperature monitoring, and refluxing in multi-component reactions. Three Necks, Two Parallel And One At Angle Adapters is priced at approximately ₹435 (indicative market benchmark, incl. GST, August 2026).
This adapter converts a single-neck flask into a three-opening setup, with two sockets aligned vertically in parallel and a third set at an angle, giving a reaction three simultaneous access points. This supports more complex multi-component procedures than a two-neck adapter allows — for example maintaining reflux through one vertical socket, monitoring temperature with a thermometer in the second, and adding reagents gradually through the angled socket. Made from high-purity borosilicate glass with vacuum-tight ground glass joints, it is suited to multi-step organic synthesis procedures taught in college and research chemistry laboratories.

Applications
- Complex multi-component organic synthesis reactions requiring three simultaneous operations
- Maintaining reflux while monitoring temperature and adding reagents
- College and research chemistry laboratories running advanced synthesis procedures
- Expanding single-neck flask capability for demanding multi-step reactions
Care & Maintenance
- Grease or fit PTFE sleeves on ground glass joints to maintain a reliable vacuum-tight seal
- Clean thoroughly after each use to prevent residue buildup at the joints
- Inspect joints for chips regularly, since a damaged joint compromises the seal
