R series of a large rotary evaporator, mainly used in biology, medicine, chemical food and other fields of the test, test, and Production. Has a large capacity, large caliber rotary evaporation bottle, placed in a water bath, rotate the heating, so that the solution of diffusion efficient evaporation. The product can be used with circulating water type multi-purpose vacuum pump, diaphragm vacuum pump, low-temperature cycle ( vacuum ) pump, circulating cooler, constant temperature cycle, low-temperature coolant circulation pump and other ancillary components of the system

We have two kinds of conventional and explosion-proof type, can be select according to the experimental environmentTeflon ( PTFE ) and fluorine rubber double rotating seal, patent technology to ensure high vacuum

The temperature control system, accurate and reliable

It does not affect the system and solution under the condition of vacuum distillation. continuous collection

The PTFE discharge valve, corrosion resistance, no pollution

1. Ask: What’s the operating principle of rotary evaporator? 
Answer: Under the condition of negative pressure, evaporating flask rotating in the thermostat water bath, which makes solution form a thin film in bottle wall, to increase the evaporation area. Evaporating efficiently under low temperature, then condensate recycling through condenser pipe and concentrate to isolate the material to reach experiment requirements. 

2. Ask: What’s the core technology of Rotary Evaporator? 
Answer: The key the s system’s gas tightness, that is whether the r system can keep p high vacuum degree under all sorts of solvent’s corrosion and movement state. Henan Lanahan’ sR series instrument, which is sealed by composite material four fluorine rubber and glass, can stand all sorts of solvent, has reliable gas tightness and can maintain a high vacuum degree above -0.096MPa. 

3. Ask: What factor decides the working efficiency of Rotary Evaporator? 
Answer: For same type equipment, mainly includes: steam temperature, vacuum degree, and cooling water temperature. Restricted by some material’s thermolability, the steam temperature may have e specific limitation when working, so high vacuum degree and low cooling water temperature are two main factors for efficiency improving (can select cryopump to lower the temperature) 

4. Ask: What’s the difference between vertical and inclined condenser? 
Answer: They have no difference essentially. The vertical condenser is gradually popular because of its small space usage and convenience for transportation and use. Most high-capacity instruments USA e vertical condenser. 

Any glassware broken after delivery voids all warranties. Thank you for understanding!
