The pilot rotary evaporator can rotate to form a thin film under constant temperature heating and negative pressure conditions, evaporate efficiently, and then cool the solvent, which is especially suitable for the crystallization, separation, and solvent of heat-sensitive materials, and some models can also do reflux extraction. It is an important instrument and equipment for scientific research and production in the biological, pharmaceutical, chemical and food industries.
It has the following advantages:
1.Sealing structure and selected sealing materials, strong corrosion resistance.
2.High evaporation efficiency, high rate.
3.Modular serial design, strong scalability.
4.It is easy to assemble and disassemble, easy to operate and easy to maintain.
5.Stainless steel (special plastic) chassis, columns, vertical shafts, aluminum alloy castings, beautiful appearance, corrosion resistance.
6.Key seals, electronic components are imported.
The role of the pilot rotary evaporator:
1.Liquid concentration: Rotary evaporators can quickly and efficiently concentrate large amounts of liquids, reducing their volume for subsequent processing or experimental analysis.
2.Separation and purification: Through rotary evaporation, different components in the mixed solution can be separated, so as to achieve the purpose of purification.
3.**Solvents: In the fields of chemical synthesis, drug preparation, etc., large amounts of organic solvents are often used. Rotary evaporators are able to efficiently ** these solvents and reduce the cost of experiments.
4.Auxiliary to other experiments: The rotary evaporator can also be used as an auxiliary equipment for other experiments that require evaporation operation to improve experimental efficiency.
Operation tips for pilot rotary evaporators:
1.Proper installation and commissioning: Before using the rotary evaporator, the equipment needs to be properly installed and debugged according to the instructions. Special care should be taken to ensure that the seals are in place to avoid air leaks or leaks.
2.Select the appropriate solvent: According to the needs of the experiment, select the appropriate solvent for rotational evaporation. For corrosive solvents, corrosion-resistant glassware and seals should be used.
3.Control temperature and pressure: In the process of rotary evaporation, the temperature and pressure should be controlled to ensure that the evaporation process is stable and safe. At the same time, it is necessary to pay close attention to the boiling point of the solvent to avoid solvent loss or equipment damage due to excessive temperature.
4.Uniform heating: In order to ensure that the evaporation process is uniform and fast, it is necessary to ensure that the liquid inside the heating jacket is evenly distributed. This can be achieved by adjusting the position of the heating jacket or by using an agitator.
5.Pay attention to safety precautions: When using the pilot rotary evaporator, special attention should be paid to safety precautions. For example, it is necessary to avoid solvent spilling to cause disasters or disastersDo not leave the device during operation to avoid accidents.
