Large Capacity Rotary Evaporator

Usage
RE-LA Series large capacity rotary evaporator with large-diameter rotary flask and large evaporation area. Vacuum water bath with rotating-edge heating improves evaporation diffusion efficiency. Suitable for small-scale applications in biological, pharmaceutical, chemical and food laboratories and production. The system can be supported with recycled-water vacuum pumps, diaphragm pumps, low-temperature cycle (vacuum) pumps, circulating coolers, constant-temperature circulators and low-temperature cooling liquid circulating pumps.

Features

• Explosion-proof device optional.
• Teflon (PTFE) and fluorine rubber dual rotating seal (patented) to ensure high vacuum.
• Imported advanced frequency control system and accurate, reliable temperature control system.
• Vacuum switching valve allows continuous collection of distillate without affecting system vacuum.
• Water bath (oil bath optional) with electric lift; manual lift option available; easy to operate.
• PTFE discharge valve: corrosion-resistant and pollution-free.
• Additional sets of glassware optional.
