The KJR-1020 Rotary Evaporator is a high-capacity and efficient system designed for the evaporation of solvents in laboratory and industrial settings. It features a large evaporating flask with a wide mouth, which increases the surface area for faster evaporation. The device operates by rotating the flask inside a water bath while reducing pressure, allowing for more effective and rapid solvent removal. This makes it ideal for use in fields such as biology, pharmaceuticals, chemistry, and food processing. The unit can be integrated with various accessories like a multi-functional circulating water vacuum pump, diaphragm vacuum pump, low-temperature circulator, and more, making it a versatile choice for different applications.
Features
1. Double sealing using PTFE (Teflon) and fluorous rubber ensures a high vacuum level.
2. Advanced frequency conversion and temperature control systems imported from abroad provide precise and reliable performance.
3. A vacuum transfer valve allows continuous collection without affecting the vacuum or distillation process.
4. Both electric and manual lifting options are available for the water bath, offering ease of use.
5. PTFE discharge valve is corrosion-resistant and non-polluting.
6. An outer protective jacket on the heating kettle prevents burns.
