ABSTRACT:
An improved sight glass for use with sampling systems employed for testing the content of chemical reaction vessels. In addition to incorporating a check valve for preventing contamination of a vacuum source, the device incorporates provision for entrapping and draining sampled fluids in the event of leakage or fracture of the glass components thereof. This is accomplished by providing an inner transparent glass tube, the inner surface of which is chemically inert, and an outer concentric tube of synthetic resinous material which surrounds the inner tube and is less subject to breakage. The cylindrical interstice between the inner and outer tubes forms a drain for retaining leakage caused by fracture of the inner tube. A floating valve cooperates with a valve seat positioned longitudinally medially of the inner and outer tubes.
