Abstract

A device is provided for taking swab samples and sample dilution. The device has a plug made of a porous, absorbent material, which projects from a sleeve and is used to take a swab sample. The plug is located in one end of the sleeve. A piston, which can be moved in the sleeve by means of a piston rod, is located in the other end of the sleeve. A closure, which can be opened by means of pressure, is located between the piston and the plug, so that a liquid arranged between the piston and the plug moves through the closure to the plug and wets same on actuation of the piston rod.
