Polypeptide synthesis device

The utility model belongs to the field of polypeptide synthesis, and particularly relates to a polypeptide synthesis device, which comprises a reactor with a cavity, a fixing device and a shaking device, a liquid outlet and a feed inlet are respectively arranged at two ends of the cavity of the reactor, and both the liquid outlet and the feed inlet are higher than the cavity of the reactor. A filtering device is arranged at one end, close to the liquid outlet, in the cavity and is parallel to the section of the cavity; the fixing device is used for fixing the reactor and is arranged in the shaking device. When the polypeptide synthesis device is applied in the polypeptide synthesis process, the reaction conditions can be stably controlled, raw materials and reagents are saved, the synthesis requirements of a large number of or multiple types of polypeptides can be simultaneously met, the stability and high-efficiency synthesis of the polypeptides are facilitated, and the polypeptide synthesis device can be wi
