Rotary evaporator with chiller and vacuum pump price
Rotary evaporator is a laboratory instrument used with Cooling chiller and vacuum pump. We produce and sell 5L, 10L, 20L and other capacity rotary evaporators, and provide supporting equipment for rotary evaporators.
The principle of rotary evaporator:
Rotary evaporators are mainly used for concentration, crystallization, drying, separation and solvent recovery in the pharmaceutical, chemical and biopharmaceutical industries. The principle is to heat the rotating bottle at a constant speed under vacuum conditions, so that the material forms a large-area film on the bottle wall and evaporates efficiently. The solvent vapor is cooled by a high-efficiency glass condenser and recovered in the collection bottle, which greatly improves the evaporation efficiency. It is especially suitable for the concentration and purification of biological products that are easily decomposed and denatured at high temperature.
Instructions for use and maintenance of rotary evaporator:
1. Check the instrument carefully before use. Whether the glass bottle is damaged and whether the interfaces are consistent. Please handle it gently.
2. Wipe each interface with a soft cloth (can be replaced by napkin), and then apply a little vacuum grease. Be sure to cover the vacuum grease after use to prevent dust from entering.
3. Each interface should not be tightened too tightly, and should be loosened regularly to avoid long-term locking and causing the connector to seize.
4. Turn on the power switch first, then let the machine run from slow to fast, and then turn off the switch when the machine is stopped.
5. Teflon switches everywhere can't be tightened too hard, it is easy to damage the glass.
6. After each use, you must use a soft cloth to wipe off all kinds of oil stains, stains, and solvent remaining on the surface of the machine to keep it clean.
7. Loosen the PTFE switches after the machine stops, and the PTFE piston will be deformed if it is in the working state for a long time.
8. Clean the sealing ring regularly by removing the sealing ring, checking whether there is dirt on the shaft, wiping it with a soft cloth, then applying a little vacuum grease and reinstalling it to keep the shaft and the sealing ring smooth.
9. The electrical parts must not be exposed to water, and it is strictly forbidden to get wet.
10. The original accessories must be purchased. Using other accessories at will will cause fatal damage to the machine.
11. When doing any repairs or inspections on the machine, be sure to cut off the power and water source first. Note that this equipment is a fragile product, please handle it carefully when using it.
