Description
The Across International R20ex Explosion-Proof Jacketed Glass Reactor is designed for synthetic reactions involving flammable solvents and hazardous chemical environments. This advanced reactor system allows precise control of temperature, vacuum, and stirring speed, while maintaining safe operation in regulated laboratory environments.
The R20ex includes explosion-proof motor, controller, and power management systems manufactured in the USA, and is PSI peer reviewed for use in Class 1 Division 1 (C1D1) environments.
Built with high borosilicate glass 3.3, solvent-resistant PTFE sealing components, and a reinforced stainless steel frame, this reactor system is ideal for chemical synthesis, pharmaceutical research, cannabis extraction, and solvent recovery applications.
What Does Explosion-Proof Mean?
Explosion-proof equipment is designed to prevent sparks or internal explosions from igniting flammable gases or vapors in the surrounding environment.
Explosion-proof electrical enclosures are built to:
• Contain any explosion originating inside the enclosure
• Prevent sparks or flashes from igniting surrounding vapors or gases
• Maintain external surface temperatures that will not ignite flammable atmospheres
Explosion-proof does not mean the equipment can withstand an external explosion. Instead, it prevents internal ignition sources from causing a larger explosion in hazardous environments.
