Abstract

A device for emission-free sampling of volatile liquids comprises a 4-way tap from which lead two lines, which can be connected together, from and to the container holding the liquid to be tested and two other lines, which can also be connected together, lead to a sample bottle which can be sealed and which can be connected to the device. The device further comprises a supply line for an inert flushing medium, which joins the line leading into the sample bottle in the region of the sample bottle, and a discharge line for the inert flushing medium, which leads from the line coming out of the sample bottle in the region of the sample bottle and proceeds to a disposal system.
