Benchtop Lab Reactor

Benchtop Lab Reactor

The Benchtop Lab Reactor is a compact, high-performance bench-scale glass reaction system designed for laboratory research, method development, and small-batch chemical synthesis. Engineered for flexibility and ease of use, this reactor is ideal for fume hood operation and constrained laboratory environments where precision and safety are critical.

Manufactured from premium Borosilicate Glass 3.3 (SCHOTT DURAN equivalent), the benchtop reactor provides excellent chemical resistance, thermal stability, and complete process visibility ????. The system supports single-wall, double-wall, or triple-wall configurations, allowing efficient heating, cooling, or insulated operation depending on process requirements.

Its modular design, compatibility with overhead stirrers, condensers, vacuum systems, and reflux assemblies, and quick-release clamping system make it a versatile solution for modern research laboratories.
