The RV131 Rotary Evaporator has wide applications in chemical, pharmaceutical, and biotechnology industries, R&D labs, and for quality assurance.
Features:
- Large LED display to easily set and monitor process parameters
- The touch keys and adjustable knob let you easily set the Rotation speed, heating temperature, operation time, and cycle times (clockwise and/or counter clockwise cycles).
- The device also comes with a mistouch prevention lock to avoid changes through accidental touch
- The adjustment knob can be turned fast or slow to change parameters rapidly or accurately.
- The 5L water-oil heating bath with heating temperature range of up to 180℃ (oil)
- The device comes with a Brushless DC motor with rotation speeds ranging from 20 to 320 rpm
- Comes with PID temperature controller, overheat protection, dry-burning protection, and automatic power-off functions
- Double-layer vertical condenser with 1500cm² cooling surface for efficient vapor collection and sample recovery
- High elastic graphite filled PTFE seal and compression spring bring excellent sealing as well as high-temperature, corrosion, and abrasion resistances.
- Manual lift for precise positioning of the glassware; the lifting height ranges up to 180mm and the tilt angle range is 0-360° (evaporation flask can be positioned on the left or right side)
- Ejection mechanism ensures easy removal of evaporating flask
- The Large LED display along with touch keys and an adjustable knob helps you easily set process parameters.
- The Double-layer vertical condenser with 1500cm² cooling surface provides efficient vapor collection and sample recovery.
