- DESIGN – SINGLE NECK ROUND BOTTOM WITH 34/45 JOINT Single-neck round bottom boiling flask with a 34/45 standard taper outer joint. The spherical bottom distributes mechanical and thermal stress evenly, making it ideal for uniform heating and vacuum applications in organic chemistry setups.
- SIZE & COMPATIBILITY – 2000 mL CAPACITY Large 2000 mL volume for medium- to high-volume reactions, distillations and solvent recovery. The precision-ground 34/45 outer joint provides airtight, leak-proof connections with matching condensers, distillation heads and adapters, and is fully interchangeable with other 34/45 joint glassware.
- TYPICAL LAB USES Designed for use as a boiling, reaction or receiving flask in organic chemistry. Suitable for batch reactions, reflux setups, vacuum or atmospheric distillation and solvent recovery in teaching labs, research labs and industrial or pilot-scale applications.
- MATERIAL & WORKMANSHIP – HEAVY-WALL BOROSILICATE 3.3 Crafted from premium 3.3 borosilicate glass with thick, heavy walls (typically 3.5–5 mm) for superior thermal and mechanical strength. Each flask is hand-blown and annealed at high temperature, allowing it to withstand direct flame heating, vacuum conditions and extreme temperature changes without cracking.
- KEY ADVANTAGES – UNIFORM HEATING & VACUUM PERFORMANCE The round bottom design promotes even heat distribution, reduced hot spots and improved resistance to stress fractures, making it more durable under vacuum than flat-bottom flasks. Durable, reusable and impurity-free, it offers reproducible performance for demanding organic synthesis and high-volume laboratory work.
