The glass separator is a new product developed in combination with the needs of biopharmaceutical field. Its performance is better than other similar products. It is mainly used for liquid-liquid extraction and can also be used for stirring reaction at room temperature. After the reaction, the materials in the tank can be released from the fully sealed discharge port at the bottom of the tank. The operation is extremely convenient. The whole system of the instrument is closed state, a multi-purpose machine, is an ideal pilot test and production system equipment for modern chemistry, fine chemical industry, biopharmaceutical and new material synthesis.
