Understanding Vacuum Metalizing Process and Applications

Evaporators work using the same principle design. A heat source is in contact with the liquid causing it to evaporate. The vapor is removed entirely (like in cooking), or it is stored for reuse (like in a refrigerator) or a product for isolation (essential oil). Rotary evaporators use a vacuum pump to create a low pressure over a solven… WebAs we mentioned above, a rotary evaporator can remove water or solvent at a reduced pressure or vacuum condition. The principle is that the water and solvent will have a lower boiling point at a reduced pressure, and thus the water and solvent can be evaporated or removed at a lower temperature. fish counter kenai river
