Introduction
Auto-lifting 20L Rotary Evaporator is designed with 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, solvent evaporates more efficiently under vacuum condition.
Mainly used for concentration, crystallization, drying, separation, and solvent recover in various fields such as, pharmaceutical, chemical, and biotechnology industries.
Highlight
- 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.
Optional
| Splash Protection | Bath pot supporting transparent cover |
