Large scale rotary evaporator is mainly used for concentration, crystallization, drying, separation and solvent recovery in the pharmaceutical, chemical and biopharmaceutical industries. Our Large scale rotary evaporator has RE-5002 50L rotary evaporator, R-1050 50L rotary evaporator and so on.
Their working principle is to heat the rotating bottle at a constant speed under vacuum conditions, and the material forms a large-area film on the bottle wall and evaporates. The solvent evaporation is cooled by the glass condenser and recovered in the collection bottle, which greatly improves the evaporation efficiency. It is especially suitable for the concentration and purification of biological products that are easily decomposed and denatured at high temperature.
Features of 50L large scale rotary evaporator:
1. Frequency conversion adjustment, imported frequency converter, stable and reliable operation.
2. It adopts PTFE and rubber compound seal to maintain high vacuum.
3. Adopt condenser to ensure high recovery rate.
4. The rotating bottle is connected with a nut for easy loading and unloading.
5. There is an automatic switching device between the auxiliary condenser and the collection bottle. The lower mouth of the collection bottle is equipped with a piston, and the recovery of the solvent is very fast. The material can be recycled continuously without stopping the machine.
6. The vacuum system is equipped with a vacuum meter, and the best working vacuum can be selected for low boiling point materials.
7. The water bath is controlled by digital thermostat and can be raised and lowered.
8. Reasonable structure and exquisite materials. The mechanical structure uses a large number of stainless steel and aluminum alloy parts. All glass parts are made of high temperature and high boron glass. The rubber seal wearing parts are all new, which is convenient for users to purchase and replace.
Precautions for using Large scale rotary evaporator:
1. Heating water bath: the general heating medium is clean water. If there is a special need for temperature, it can be replaced with silicone oil or high-temperature silicone oil. Close the lid in time to prevent dust from entering the water bath or oil bath and keep the water bath or oil bath clean.
2. Condenser: The general cooling medium is water. If the ambient temperature is high and the condensation effect is not good, it can be replaced with ethanol and equipped with a circulating refrigerator. The ethanol after cooling is pressed into the condenser for cooling treatment. In cold weather, when the condenser is not in use, the water in the condenser should be drained overnight to prevent the water from solidifying, expanding in volume, and bursting the condenser.
3. Decompression equipment: often configured as a water pump. For some solvents with high boiling points, the water pump can be replaced with an oil pump. Pay attention to the requirements of the equipment when replacing it.
