Overview
HR-21M Rotary evaporator is a HUXI brand equipment, mainly used for the continuous distillation of a large number of volatile solvents under reduced pressure conditions, especially suitable for the condensation of the extract and the distillation of the receiving liquid during chromatograph separation, which can separate and purify the reaction products. The basic principle is vacuum distillation. When the solvent is distilled under reduced pressure, the distillingflask rotates continuously.
Features
1. Automatic lifting, simple, stable and reliable structure, allowing laboratory operators to easily operate with one hand.
2. LCD controller, multiple sets of data are displayed on one screen, menu-type operation interface, knob-type setting, easy to understand, easy to observe and operate;
3. PID controller, speed, temperature, time setting is simple and fast;
4. Unique oblique double-decked serpentine coil design, with a chill down area of 0.15 square meters and a maximum evaporation capacity of Max.22ml/min, ensuring effective recovery from small to large amounts of samples;
5. Double-decked effective condenser, designed to prevent evaporation condenser backflow, and the condenser position can be adjusted;
6. Professional sealing system design, high resilience PTFE material sealing ring, with high temperature resistance, corrosion resistance, durability and other characteristics, reduce the frequency of laboratory operators changing sealing pads frequently, more than double the service life of traditional manufacturers sealing ring;
7. Water bath/oil bath double heating mode, external heating, convenient for users to clean the bath pot.
Principle
HR-21M Rotary evaporator is based on the principle of vacuum distillation. Under vacuum conditions, the distillingflask rotates continuously during solvent distillation to achieve efficient evaporation and separation.
Applications
Extraction solution condensing, chromatograph separation of receiving solution distillation, separation and purification of reaction products
Steps
1. Set the speed, temperature and time parameters.
2. Start the equipment for decompression distillation;
3. Adjust the condenser position as needed;
4. Turn off the equipment after completing the distillation.
Notice
• Ensure that the working environment temperature is within the range of 5~ 35 ° C;
• Check whether the sealing ring is in good condition before use to avoid frequent replacement;
• Pay attention to the external heating design when cleaning the bath pot;
• Follow safety regulations for vacuum distillation during operation.
