20L Lab rotary evaporator

20L rotary evaporator consist of 100% Borosilicate 3.3 glass material durable in high temperature.
Optimized evaportion flask mouth gives maximum evaporation rate.
Bright LCD screen for easy setting and reading.
Bottom drain valve enable you to empty the receiving flask at ease.

It is suitable for pilot-level experiments in biology, medicine, chemical industry, food and other fields. It forms a supporting system with vacuum pumps, circulating coolers and other cooling equipment. Excellent sealing design, the system boost rate ≤ 2Kpa/h without vacuum grease; Automatic switching valve design, under the configuration of single collection bottle, it can be continuously distilled to export the collection bottle material; PTFE discharge valve; The glass assembly is connected by a quick flange, which is easy to operate.

Applications

Large capacity and large opening of evaporating flask give larger evaporation surface. 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.

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.
