How to choose a set of durable rotary evaporator

The rotary evaporator is a commonly used separation device in chemical and biological laboratories. It can efficiently evaporate and separate the solvent in the solution and is widely used in experimental operations such as sample concentration and purification.

How to choose a set of durable laboratory rotary evaporator?

1. Sealing performance is crucial for selecting a set of durable rotary evaporator. Sealing is the primary consideration for a rotary evaporator. It is crucial for the instrument's proper operation and service life. "Actual vacuum level" and "vacuum holding time" are specific criteria.

2. The lifting mode can be selected as automatic lifting or seesaw electric lifting, which is easy to use.

3. The grinding mouth of the collecting bottle is generally ball-milled and standard. The grinding mouth of the rotating bottle is of two specifications: 24 and 29. The 29 grinding mouth is commonly used. It has high strength and is easy to clean. It is also convenient for selecting a bottle return device.

4. A vacuum pump is essential for a rotary evaporator. While rotary evaporators typically use a circulating water vacuum pump, rotary evaporators with a vacuum controller utilize a corrosion-resistant diaphragm vacuum pump.

5. Condensation performance: Tap water temperature varies significantly with the seasons. Summer temperatures are relatively high, resulting in low solvent recovery rates. Furthermore, tap water can easily cause discoloration and scaling in the condenser.

Rotary vacuum evaporators often need to be used in combination with other equipment and accessories to meet different experimental needs. The application of a rotary evaporator with a combination of other equipment and accessories not only improves the efficiency and safety of the experiment, but also helps protect the environment and conserve resources.
