Shanghai Xinzhuang Instrument Co., Ltd. is a leading company that combines R&D, production, and sales, dedicated to innovation in science and technology. With a strong focus on developing high-quality rotary evaporators, the company has made significant contributions to scientific research and industrial applications. Their products are widely used in laboratories for efficient solvent evaporation and sample concentration.
Before using the rotary evaporator, it's essential to check if the vacuum system works properly. If the vacuum cannot be achieved, make sure the bottle is sealed correctly, the vacuum pump isn't leaking, and the sealing ring is intact. Installing an external vacuum switch can enhance both the evaporation speed and recovery rate.
To start the process, connect the hose to the feeding port so that the liquid material can be drawn into the rotating flask under vacuum. Ensure the liquid doesn’t exceed half the capacity of the flask. The system allows continuous feeding, but always turn off the vacuum pump and stop heating before adding more material. After evaporation, slowly open the valve to prevent backflow.
The water bath must be filled with water before turning it on. The temperature setting (0–99°C) should be adjusted according to actual conditions, as thermal inertia may cause the real temperature to be about 2°C higher. Adjust the set value accordingly for accurate results.
When operating the device, first turn on the power switch and adjust the speed control knob for optimal performance. Avoid sudden changes in the water bath temperature and ensure the cooling water is running smoothly.
After the process is complete, open the feed valve to release pressure, then turn off the vacuum pump and remove the solvent from the collection flask.
Before installation, apply a thin layer of vacuum grease to all connections and ensure the sealing rings are in place. This helps maintain a proper vacuum seal and prevents leaks.
Some important safety tips include:
- Always check the glass components for cracks or damage before use.
- Wipe all interfaces with a soft cloth and apply a small amount of vacuum grease. Store the grease properly after use.
- Do not over-tighten any connectors, as this may cause long-term damage.
- Start the machine at a low speed and gradually increase it. Always turn off the power when stopping.
- Avoid over-tightening PTFE valves, as this can damage the glass parts.
- Clean the machine regularly to remove oil stains, residues, and solvents.
- After use, loosen the PTFE switches to prevent deformation of the piston.
- Regularly clean the sealing rings and apply vacuum grease to keep them smooth.
- Keep electrical components dry and avoid contact with water.
- Only use original accessories to prevent damage to the equipment.
- Always disconnect the power and water supply before performing maintenance or inspections.
- Handle the equipment carefully, as it is a delicate instrument. Any damage caused by mishandling is not covered by warranty.
