Abstract
A sampling device for solids from a pressure reactor includes a housing which is connected to the reactor and accommodates a tube with its one end opening into the reactor. Movable within the tube is a sampling piston which is provided with gas-impermeable piston rings. To withdraw solids from the reactor, the piston is moved into the reactor such that the forward piston ring projects into the chamber of the reactor and is then retracted with a solids sample arranged in between the piston rings. The piston is moved to an opening of the tube so that the solids sample can be discharged to the outside.
