1. How to choose various rotary evaporators?

In terms of structure, our R series products have excellent corrosion resistance and leak resistance. Depending on the volume of the solvent, 2L, 3L, 5L machines are suitable for laboratory and sample testing; 5L, 10L, 20L machines are suitable for medium-sized experiments; 20L, 50L machines are suitable for medium-sized experiments and production, especially for metal ion extraction, avoiding Contaminants.

2. How to choose a vacuum pump for the rotary evaporator?

We recommend a water circulation pump that can withstand various solvent corrosions and can be evacuated to -0.095 MPa (to meet the requirements). Depending on the amount of solvent, we can supply various types of vacuum pumps.

3. What are the characteristics of a rotary evaporator compared to other evaporators?

The structure is small, efficient, easy to observe, and free from metal ion pollution. It is suitable for laboratory, production and valuable material extraction. Its leak-proof capability is comparable to that of foreign equipment, and there is still room for improvement in terms of appearance and user-friendly design.

4. What is the explosion-proof capability of the series rotary evaporator?

Our company's rotary evaporator uses an alternator, stepless speed regulation (or frequency control), no brush, no spark. The water bath used with the evaporator is controlled by a nitrogen sealed relay, a silicon controlled non-contact switch and a vacuum switch. The manual control switch uses two circuit controls with a current of less than 3 mA and a good explosion-proof function.
