Why high vacuum can keep for YEARS without maintainence?
- Because of Mechanical Sealing.
Traditional O-ring Seal
Main seal and evaporation flask are rotating but the vapor duct is fixed.
O-ring in the main seal is the key seal part between main seal and vapor duct, so O-ring is heavily prone to be worn out by friction, especially under corrosion of solvent, which requires regular operation stop, disassemble and O-ring change.
We apply mechanical seal in rotary evaporator, whose vapor duct, main seal and evaporation flask rotating together, without moving in between.
So the O-ring in main seal has no chance to be worn out and no need to change it at all.
Reinforced PTFE + SiCmechanical seal is tight, durable, long lasting and great for 24/7 operation.
