[0002] In modern biopharmaceuticals, fine chemicals, and new material synthesis experiments, glass reactors are widely used as ideal experimental equipment. Glass reactors have the structural characteristics of double-layer glass, and the reaction medium can be introduced into the middle interlayer. Under normal pressure or negative pressure, the reactants are stirred and reacted in a sealed glass container. The fully transparent glass characteristics make the entire reaction process clear at a glance. The motor in the existing glass reactor will vibrate during operation, and the vibration will be transmitted to the glass reactor body through the reactor cover. However, the equipment lacks the corresponding shock-absorbing structure and cannot achieve elastic compression and vibration buffering. Therefore, the reactor body collides with the support member below that acts as a limiter. The support member is relatively hard, which can easily cause wear or even rupture of the reactor body, increasing production costs. Utility Model Content
