ABSTRACT:
A device for single usage for sampling liquids consisting of a hollow mounting tube closed at one end by a base which has a needle mount and into which can be slid a sampling tube. The sampling tube has a cap which has a diameter in the section of the cap projecting from the tube greater than the diameter of the tube to thereby form a shoulder. The mounting tube consists of a head into which the cap of the sampling tube slides, a body to guide the sampling tube, and internally projecting studs to retain the cap in the mounting tube. A breaking point is formed where the head and body join which must be broken in order to withdraw the sampling tube from the mounting tube after a sample has been taken.
