Description
Applications
Large capacity and large opening of evaporating flask give larger evaporation surface. GWSI supply great quality rotary evaporator for sale to clients in the world. The evaporating flask keeps rotating when it is constantly heated by water bath, and solvent evaporates more efficiently under vacuum condition. It 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, diaphragm vacuum pump, recirculating chiller, constant-temperature circulator, low temperature circulating pump, etc.1
Advantages
● Patented technology of double sealing of Teflon(PTFE) and FV rubber ensures the negative pressure level.
● Automatic switch valve makes continuous collection possible without affecting vacuum degree and without stopping distillation.
● Teflon discharge valve is corrosion resistant and contamination free.
● Water bath jacket protecting operator from scalding by hot liquid.
● Motorized water bath lifting for precise control.
● Quick clamp connections for easy and fast installation.
● PID temperature controller ensures accurate temperature control is maintained.
● Optional stainless steel evaporating flask carrier with silicone cushions is designed for safer and easier loading and unloading of the flask. It can also be used as a flask stand.
