Explosion-proof Rotary Evaporator
R-2020Ex
Features:
High borosilicate 3.3 glass has good physical and chemical properties.
Main and auxiliary condensers, high efficiency triple-circulating condensing tube has bigger condensing area.
High borosilicate glass three-way flask, prevent flushing and bumping, ensure safe operation.
Patented technology of double sealing of Teflon (PTFE) and FV rubber ensures negative pressure level.
Auto switch valve makes continuous collecting possible without affecting vacuum degree and without stopping distillation.
The motor, heater, electric control box and liquid level switch are all explosion proof type, explosionproof grade: ExdⅡBT4, all explosion-proof parts have certificates from manufacturer.
Motorized stainless steel water bath, has liquid level protection and anti-dry burning functions.
Quick-release valve for easy installation and removal of glass components.
PTFE discharge valve is corrosion resistant and contamination free.
Lockable casters, easy to move and lock.
