ABSTRACT:
A sampling apparatus for taking samples of a toxic fluid from within a shded chamber has a rotatable shaft which extends downwardly through the shielding wall and is provided at its front end within the chamber with a cavity adapted to receive sampling bottles supplied thereto and removed therefrom through supply and return pipes. A hollow needle is mounted on a needle head disposed in front of the shaft such that the needle can be inserted into a sampling bottle disposed in the shaft cavity and sample fluid can be injected into the bottle from the needle head to which the fluid is conducted by a supply line and from which it may be removed through a discharge line.
