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, with pressure relief device to
make the solvent evaporated more efficiently. 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.
- Patented technology of double sealing of Teflon(PTFE) and FV rubber
can ensure the negative pressure indicators.
- Vacuum switch valve makes continuous collection possible without
affecting system negative pressure indicators and solvent
- Teflon discharge valve is corrosion resistant and caused no
- Water bath jacket protecting operator from injury by hot liquid.
- One year warranty and life-long after-sale support.
- All of the motors, heaters and electric control boxes are
explosion-proof type. The Ex degree is dIIBT4.
- The electric control box is installed independently and easy to
Packaging & Shipping
