Explosion-proof Vacuum Evaporator Distillation Apparatus 5L 10L 20L 50L Rotary Evaporator Price
Product Description
With high capacity and large diameter rotary flask,this rotary evaporator series can be used for pilot-scale production in biology engineering, pharmaceutical industry, chemical industry and food processing. It usually works with water circulating vacuum pump, daphragm vacuum pump, recirculating chiller, constant temperature circulator, low temperature circulating pump, etc.
The explosion-proof type is the same as normal rotary evaporator series except the motors, heaters and electric control box are all explosion-proof.
