Abstract: This Paper presents a newly designed multipurpose VLEdeterminatingapparatus—CS- Ⅱ VLEdeterminating apparatus and discusses the ideas of theapparatus design. With the features and functions of both VLEstill and ebulliome-ter, it has a pump-like stirrer so that it can be used appropriately to quasi-static method; it has a new structure of sampling vessels and valves, which makes it applicable to both miscible and partially miscible solution systems and appropriate to the system with high boiling temperature difference of components. The detail results of the experimental verification are given in this paper.

Key words: Vapor-liquid equilibria, Ebulliometer, Still, Pump-like stirrer
