Most Chemistry labs have tongs that allow you to grip or hold small test tubes so you will not burn your hand or spill harmful chemicals on your fingers. They are usually simple metal tongs that are flat but the ends are curved to the radius of the test tube.
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 tubesthrough 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 testtubes introduced. To achieve this, the multipleholder 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 testtubes 2 introduced can be broken off simultaneously at least at one end.
