Large 100L rotary evaporator manufacturer price for sale，Rotary evaporators are mainly used for concentration, crystallization, drying, separation and solvent recovery in the pharmaceutical, chemical and biopharmaceutical industries. The principle is that under vacuum conditions, the temperature is heated at a constant temperature to rotate the rotating bottle 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 a collection bottle to greatly increase the evaporation efficiency. It is especially suitable for the concentration and purification of biological products which are easily decomposed and degenerated by high temperature.

1. When receiving the 100l rotary evaporator installation, please fix the screw parts of each interface with the matching tools to avoid damage to the machine parts or glass breakage caused by bolt problems.

2. The interface or the sealing ring and the sealing surface are cleaned. The position of each bolt is arranged well, otherwise the rotating spindle will be rotated together.

3. Before installing the condensate bottle, first set the rim clamp. After placing the bottle, adjust the position to tighten the bolt. Connect the upper port to the vacuum connector. One condensate bottle is used to feed water into a effluent. The lower the water temperature used, the better.

4. Need to pay attention to the switch device, one switch is connected to the deflation and feed port, there is an automatic and manual switch configuration, both can be used.

5. The glass parts should be cleaned and carefully placed during installation. The seal is inspected in advance for aging and cracks. If there is a problem of leakage during use, and if there is no problem with each part, take out the seal and apply vacuum grease, and the sealing will be better.

6. After the vacuum joint is connected, always pay attention to whether there is air leakage or damage during use, and replace it in time.

7. Lifting device, if there is an emergency during use, use the manual handwheel to stop it.

8. Follow the instructions for use. If the instructions do not match the instrument, the operator will promptly solve the problem.

Safety issues in the use of large 100L rotary evaporators require detailed knowledge by the staff to avoid danger.
