RE-2000ABE digital rotary evaporator is a small rotary evaporator independently developed by our company, including three models: RE-2000A rotary evaporator, RE-2000B rotary evaporator, RE-2000E rotary evaporator. It adopts two lines of large-capacity blue backlit liquid crystal display. The interface and the control part use a high-performance single-chip microcomputer as the main control chip. The price is cheap, the operation is simple, the quality is stable, and it is economical and practical. It is suitable for drying, purification, recovery and other operations in the fields of separation, crystallization, biopharmaceuticals, medicine, chemical engineering, etc.

RE2000A RE2000B RE2000E rotary operation method:

1. Prepare:

After assembling the machine, connect the cryopump and vacuum pump according to the connection diagram of the supporting equipment;

Turn on the cryopump;

·Turn on the vacuum pump, start vacuuming, and pay attention to the reading of the vacuum gauge. When the vacuum gauge maintains the maximum vacuum for a period of time, it indicates that the equipment is well sealed and can start feeding.

2. Feeding method:

First pump the digital rotary evaporator into a negative pressure state, connect the feeding valve with the sample to be added with a hose, open the feeding valve, the sample will be directly pumped into the rotary bottle, and close the feeding valve after the feeding is completed .

·It is recommended that each addition should not exceed 1/2 of the volume of the rotary bottle.

3. Adjust the height of the bath so that the rotary bottle is placed in the water bath:

·Adjustment method: electric lifting, after turning on the power, press the button on the rotating machine head to adjust the height of the rotating bottle, press the upper triangle to raise, press the triangle to lower.

·Pour pure water into the bath, submerge 1/2 of the spinner bottle, just don't overflow.

· Setting up the controller panel

4. Temperature setting:

Method: Turn on the heating switch, press the "SET" key to enter the temperature setting program, a dot is flashing in the lower right corner of the digit being edited, press the "

5. Rotation settings:

Method: Turn on the motor switch, turn the speed control knob to adjust to the required speed, turn it clockwise to increase the speed, and turn it counterclockwise to decrease the speed. RE2000B has speed display, RE2000A has no speed display.

6. Non-stop feeding:

After the rotary evaporator works normally for a period of time, the raw material solution in the rotary bottle may have been evaporated, but there is still a lot of space in the receiving bottle. When you want to evaporate some raw material solution but do not want to start vacuuming again, please repeat Addition method of step 2.

Instrument maintenance:

1. The PTFE switches everywhere should not be tightened too hard, as it is easy to damage the glass.

2. After each use, you must use a soft cloth to wipe off all kinds of oil stains, stains, and solvent residues left on the surface of the machine, and keep it clean.

3. Unscrew each PTFE switch after stopping the machine, and the PTFE piston will be deformed if it is still in the working state for a long time.

4. Clean the sealing ring regularly. The method is: take off the sealing ring, check whether there is dirt on the shaft, wipe it off with a soft cloth, then apply a little vacuum grease, and reinstall it to keep the shaft and the sealing ring smooth.

5. The electrical part must not enter the water, and it is strictly forbidden to be damp.

6. Before maintenance, please turn off the power switch, and disconnect the power cord from the power supply.

7. When cleaning, please wipe with a soft cloth wrung out of water, and use neutral detergent for dirt that is not easy to remove. Wipe clean with a rag after using detergent.

8. The maintenance of internal electric control components and heating components must be operated by professionals or professional electricians.

FAQ:

1. What is the working principle of the digital rotary evaporator?

Heating at constant temperature, rotating under negative pressure to form a film, and at the same time, the solvent is evaporated, condensed and recovered. It is especially suitable for the concentration, crystallization, separation and recovery of heat-sensitive materials.

2. What are the uses of the digital rotary evaporator?

It is generally used for separation, crystallization, drying, purification and other operations in biopharmaceutical, pharmaceutical, chemical, chemical and other industries.

3. How to choose a vacuum pump for a digital rotary evaporator?

It is recommended to choose a circulating water vacuum pump, which has the advantages of corrosion resistance, no pollution, and fast vacuuming speed. According to your needs, we can provide various types of circulating water vacuum pumps.

4. How long can the digital rotary evaporator work continuously?

The rotary evaporator can work all the time, but we recommend stopping it for maintenance after running for a period of time. Regular maintenance can increase the service life of the equipment.

5. What is the material recovery rate of the digital rotary evaporator?

The material recovery rate of the rotary evaporator produced by our company is very high, and the recovery rate is generally between 95-99%.
