Both vacuum evaporation and vortex evaporation are two sample preparation processes that are used to remove moisture from a sample. Vacuum evaporators are used to evaporate liquids through the application of pressure and is sometimes in conjunction with temperature to be reduced below a sample’s vapor pressure. Vortex evaporators are also used to remove liquids to concentrate a sample for sample preparation. Unlike a vacuum evaporator, a vortex evaporator uses vortex motion for this process. Applications include environmental testing, drug development, toxicology, pharmaceutical, forensics, food, semiconductor, and chemistry.

The upright stainless steel collector coil holds 2.5 liters of ice before defrosting. Two 1/3 hp HCFC/CFC-free refrigeration compressors cool the collector to -84°C, suitable for aqueous or dilute acetonitrile samples. Temperature-controlled shelves range from -55°C to +50°C (-67°F to +122°F) and a maximum of -75°C (-103°F) during pre-freezing. The shelves provide pneumatic stoppering with a diaphragm, eliminating the need for compressed gas....
