DW-5210A DW-5220A Large Capacity Floor Type Rotary Evaporator
DW-5210A and DW-5220A are floor-standing rotary evaporators designed for larger-volume laboratory evaporation, concentration and solvent recovery. The series combines 10–130 rpm rotation, automatic cantilever lifting, large-area vertical condensers and continuous condensate discharge, with Standard and Vacuum Control configurations available.
- Sample Flask Capacity: 5–10 L / 5–20 L
- Maximum H₂O Evaporation Capacity: 3.5 / 5 L/h
- Rotation Speed: 10–130 rpm
- Condenser Area: 0.58 / 0.96 m²
- Automatic Lifting Stroke: 160 / 190 mm
- Water Bath: RT–99°C ±1°C
Features of DW-5210A 5220A Large Capacity Floor Type Rotary Evaporator
- Large LCD Control: Menu interface and knob input make parameter setting and process monitoring easier.
- Continuous Condensate Discharge: The pressure-retaining valve allows recovered liquid to be discharged without interrupting vacuum operation.
- Forward / Reverse Rotation: The rotation direction can be alternated with an adjustable interval of 0–60 s for compatible powder-drying workflows.
- Automatic Lifting: Electric lifting provides stable flask positioning with a preset safety-distance limit.
- Large-Area Condenser: The integrated three-reflux, large-diameter condenser supports high-volume evaporation and solvent recovery.
- PTFE-Based Process Components: PTFE sealing materials and the molded Teflon heating bath improve corrosion resistance, wear resistance and cleaning convenience.
Safety & Practical Design
- Automatic Stop & Standby: The system stops automatically after the process and separates the evaporation flask from the heating bath.
- Multiple Safety Protection: Protection functions include overcurrent, overload, fuse, dry-heating and overtemperature protection.
- Floor-Standing Mobile Design: The lower frame provides space for compatible vacuum equipment, while casters and positioning devices support movement and stable installation.
- Transparent Bath Cover: The protective cover helps reduce heat loss and limits splashing during operation.
