Rotary evaporator to buy the relevant questions and answers:
1, Q: rotary evaporator How does it work?
A: negative pressure conditions, the evaporation in the constant temperature water bath pot bottle rotation, the solution to form a thin film in increase the evaporation area. Under the high-performance low-temperature evaporation, condensate recovery, separation of material enrichment.
2, Q: rotary evaporator What is the core technology?
A: Yes, gas-tight system, that is, the erosion in a variety of solvents, in campaign mode, the system can maintain a high vacuum. I plant R series rotary evaporator, the use of rubber PTFE composite material and glass sealing, the ability of various solvents, are durable and reliable air tightness can be maintained above the high-0.096MPa vacuum.
3, Q: the impact of the efficiency of rotary evaporator What are the main factors?
Answer: The specifications on the same machine, the main are: steam temperature, vacuum and cooling water temperature. Heat-resistant materials are not subject to certain constraints, the work simply can not indefinitely increase the steam temperature, the high vacuum and low cooling water temperature is to improve the efficiency of the two main factors (the use of cryogenic pumps, lowering the water temperature).
4, Q: vertical and oblique condenser condenser What's the difference?
A: no significant difference in nature. Condenser as a result of vertical space in small, gradually be welcomed. Large-capacity vertical evaporator condensers generally.
5, Q: host take-off and landing and take-off and landing in a water bath pot design is based on what?
A: convenience, security and economic principles, the international community in general small machines (5L) in the host take-off and landing, 5L pot more than take-off and landing in a water bath.
6, Q: R series of explosion-proof evaporator How?
A: I plant the production of the rotary evaporator using AC motor, stepless speed regulation (or Frequency), no brush, no spark operation. Pot of water with the match were used to control Nitrogen sealed relays, SCR non-contact switch, vacuum switch. Manual control switch to control the use of the second line, control current of less than 3mA, explosion-proof characteristics of a good.
7, Q: how to purchase various types of rotary evaporator?
A: I am on the terms of the structure of production of various types of R series rotary evaporator good corrosion resistance and sealing. 2L, 3L, 5L machine is suitable for laboratory and sample test; 5L, 10L, 20L suitable test; 20L, 50L is suitable for test and production, in particular the need to avoid the application of metal ions in this material extraction.

8, Q: rotary evaporator and the evaporator compared to other types of what?

A: The main advantage is its compact structure, compact and efficient, intuitive work, no metal ion contamination. Apply to laboratory, pilot production and the extraction of valuable materials. The sealing performance of the machine can be comparable to foreign countries, but in appearance and user-friendly design could be improved.
9, Q: rotary vacuum evaporator how to choose?
A: We recommend water pump, the advantages of its corrosion-resistant variety of solvents can be pumped to a vacuum-0.095MPa (to meet the use requirement). Vacuum evaporator Volume according to the size, selection of different models, our factory can supply various models of vacuum pump package.
