Rotary rotary evaporators are mainly used for concentration, crystallization, drying, separation and solvent recovery in the pharmaceutical, chemical and biopharmaceutical industries
.
The principle of the rotary evaporator is: under vacuum conditions, constant temperature heating makes the rotary bottle rotate at a constant speed, and the material forms a large-area film on the bottle wall and evaporates
.
The solvent vapor is cooled by a glass condenser and recovered in the collection bottle, which greatly improves the evaporation efficiency.
It is especially selected for the concentration and purification of biological products that are easily decomposed and denatured at high temperature
.
The rotary rotary evaporator integrates the essence of similar products at home and abroad, and integrates the successful practical experience of the factory.
The product design follows the principles of practicality and economy
.
Rotary Evaporator Instrument Maintenance 1.
Carefully check the instrument before use, whether the glass bottle is damaged, whether the rotary evaporator and each interface are consistent, and pay attention to handling
.
2.
Wipe each interface with a soft cloth (can be replaced with a napkin), and then apply a little vacuum grease
.
Be sure to cover the vacuum grease after use to prevent lime and sand from entering
.
3.
Each interface should not be over-tightened, and it should be loosened regularly to avoid long-term locking that will cause the connector to die
.
4.
Turn on the power switch first, then let the machine run from slow to fast, rotate the evaporator parameters, and stop the machine when it stops, and then turn off the switch
.
5.
The PTFE switches around the rotary evaporator should not be over-tightened, which will easily damage the glass
.
6.
After each use, all kinds of oil stains, stains and solvent residues left on the surface of the machine must be wiped off with a soft cloth to keep it clean
.
7.
Unscrew each PTFE switch after stopping, and the PTFE piston will be deformed if it is still in the working state for a long time
.
8.
Clean the sealing ring regularly.
The method is: remove the sealing ring, check whether there is dirt on the shaft, wipe it with a soft cloth, then apply a little vacuum grease, and then reinstall it.
The rotary evaporator keeps the shaft and the shaft.
The sealing ring is lubricated
.
9.
The electrical part must not enter the water, and it is strictly forbidden to get wet
.
