Ace Glass 72 Liter Round Bottom Reaction Flask

The Ace Glass 72 Liter Round Bottom Reaction Flask is a high-capacity, heavy-wall borosilicate vessel designed for laboratories and pilot-scale chemical synthesis. Built from 33 expansion borosilicate glass (equivalent to Pyrex®), it delivers outstanding resistance to thermal shock, exceptional chemical durability, and long-term reliability across a wide range of demanding laboratory processes.

At HiTechTrader, we offer carefully refurbished and pre-owned Ace Glass reaction flasks that retain the same robust performance of new equipment, at a fraction of the cost. Each vessel is inspected for durability, seal integrity, and structural soundness, making it an ideal choice for chemical research, pharmaceutical development, and industrial-scale experiments where both performance and budget matter.

2. Suitable for heating, reflux, distillation, and solvent recovery.
3. Excellent thermal shock resistance when heated gradually.

Typical Applications

1. Chemical synthesis and pilot-scale batch reactions.
2. Pharmaceutical and industrial R&D.
3. Controlled-temperature studies and reaction monitoring.
4. Distillation, reflux, and solvent recycling processes.

Accessories & Compatibility

1. Compatible with Ace Glass 200 mm vessel lids.
2. Works with condensers, funnels, stirrer shafts, thermowells, and temperature probes.
3. Requires additional support and heating equipment (sold separately).

Safety & Maintenance

1. Operate only within rated pressure and temperature limits.
2. Inspect regularly for cracks or worn seals; avoid mechanical shocks.
3. Use genuine APS seals and PTFE components for leak-free operation.
4. Clean and maintain routinely to extend service life.
