YIHENG BRE-20 pilot-grade Rotary evaporator is a laboratory instrument, mainly used for the continuous distillation of a large number of volatile solvents under reduced pressure conditions, especially for the condensation of the extraction liquid and the distillation of the receiving liquid during chromatograph separation, which can separate and purify the reaction products. The basic principle is vacuum distillation. During solvent distillation under reduced pressure, the distillingflask rotates continuously.
1. Large capacity, large diameter swirl/spin bottle, large evaporation area, placed in the Water bath side swirl/spin side heating, equipped with a decompression device to effectively evaporate the solvent, suitable for biological, chemical, food and other fields of pilot, can be combined with diaphragm vacuum pump, circulating chilled down device and other supporting devices. 2. LCD multiple sets of data on one screen display, Menu Operating interface, knob setting is easy to understand, PID controller makes Rotation speed, temperature, time setting simple and fast. 3. Bath pot automatic lifting device, multi-wedge belt drive vibration is small, stable lifting, simple structure, low noise, easy to operate. 4. Double-decked effective condenser pipe has a large chilling down area and strong evaporation capacity, ensuring that samples from a small amount to a large amount can be effectively recovered. 5. Professional sealing system design, high resilience PTFE material sealing ring high temperature resistance, corrosion resistance, durable, reduce frequent replacement of sealing pad Frequency, more than double the service life of traditional manufacturers sealing ring. 6. With automatic switching valve, continuous collection is carried out without affecting the negative pressure index of the system and solvent distillation. 7. Teflon discharge valve is convenient to quickly release the material received in the recovery bottle, corrosion resistance, no pollution. 8. The box is made of casters with anchor bolts, which can be fixed to the ground during operation, ensuring a stable and reliable experimental process without accidents. 9. Water bath/oil bath double heating mode, with anti-dry burning and power failure function, the pot body is made of high temperature flame retardant material to prevent accidents (standard water bath). 10. Automatic control, optional vacuum controller to control the Vacuum Level of the sample, to achieve solvent separation automation. 11. The shell of the pot and the liner are designed with a special thermal insulation structure to keep the surface temperature of the shell of the pot low and avoid burns by the experimenters. 12. The inner layer of the bath is made of Teflon coating, which is resistant to high and low temperature, corrosion resistance, easy to clean, and avoids cross-contamination during the experimental process. 13.Double-decked effective condenser to prevent evaporation condenser backflow design. 14. Water bath Safety level design, with the function of preventing dry burning and power failure, the pot body is made of high temperature flame retardant material to prevent accidents. 15. The pot is equipped with an independent temperature limit alarm system, which automatically stops working after exceeding the temperature limit to ensure the safe operation of the test. 16. Safety protection of key electrical components such as overcurrent, overtemperature and overload can prevent equipment accidents. 17. When the equipment malfunctions, the display screen will display fault information to ensure that the fault information is clear at a glance.
The basic principle of the Rotary evaporator is vacuum distillation. During solvent distillation under reduced pressure, the distillingflask rotates continuously to promote solvent evaporation through heating and swirl/spin, thereby achieving separation and purification.
Biology, chemicals, food
1. Rotation speed, temperature and time parameters. 2. Place the swirl/spin bottle in the Water bath and start the heating. 3. Start the swirl/spin and decompression unit for distillation. 4. Use automatic switching valve to collect solvent continuously. 5. Quickly release the material in the recovery bottle through the Teflon discharge valve.
• Make sure the equipment is fixed on the ground to prevent accidental movement. • Pay attention to avoid burns during operation, because the surface temperature of the pot shell is low but the heating part may be high temperature. • Regularly check the sealing ring and electrical components to ensure that the Safety protection function is normal. • Water bath to prevent dry burning, use anti-dry burning power function. • Use appropriate methods when cleaning the inner layer of the bath to avoid cross-contamination. • Monitor the display screen of the equipment and deal with the fault information in a timely manner.
