（Product features）：

● Adopting a composite seal of polytetrafluoroethylene and rubber, it can maintain a high vacuum degree.

● Using an efficient condenser to ensure high recovery rates.

● The rotating bottle is connected with a nut for easy loading and unloading.

● The collection bottle is equipped with a piston at the bottom, which makes the solvent recovery very fast.

● Can be continuously fed.

● Install a vacuum gauge in the vacuum system. The optimal working vacuum degree can be selected for low boiling materials. 7. The digital constant temperature control of the water bath pot can be adjusted up and down by 0 degrees

● Reasonable structure and meticulous material selection. Stainless steel and aluminum alloy components are widely used in mechanical structures. All glass components are made of high-temperature and high boron glass, and key electrical components are imported. All rubber sealing vulnerable parts adopt new national standards, making it easy for users to purchase and replace.

（Application scope）：

Rotating evaporators are mainly used for concentration, crystallization, drying, separation, and solvent recovery in the pharmaceutical, chemical, and biopharmaceutical industries. The principle is: under vacuum conditions, constant temperature heating is used to make the rotating bottle rotate at a constant speed. The material forms a large-area thin film on the bottle wall for efficient evaporation. The solvent is evaporated and cooled by an efficient glass condenser, and then recycled into a collection bottle, greatly improving the evaporation efficiency. It is particularly suitable for the concentration and purification of biological substances that are prone to decomposition and denaturation at high temperatures.

The rotary evaporator of our company gathers the essence of domestic similar products, and has formed 2L, 5L, 10L, 20L and 50L series based on our successful practical experience. The product design follows the principles of efficiency, practicality and economy, and is all for the sake of users.
