ABSTRACT:
The present invention pertains to a multiple holder for test tubes, which receives a plurality of individual test tubes for the simultaneous flow-through of a gas sample with the gas entering the tubes through at least one opened end, from a connection piece which has a flow outlet. The multiple holder of the invention receives commercially available test tubes with fused tips and includes an arrangement to simultaneously open all the test tubes introduced. To achieve this, the multiple holder 1 is designed such that at least one section 6, 6a can be tilted down, as a result of which the tips 8 of all the test tubes 2 introduced can be broken off simultaneously at least at one end.
