ABSTRACT:
A holder for a test tube with a test robe tip that can be opened, with a tube, which accommodates the test tube at least partially, and whose tube end has a projection pointing toward the test tube tip in the area of the test tube tip. The handling steps needed to open the test tube are reduced by providing a projection beginning from the tube end, with a cross-sectional area decreasing continuously over at least a section. A displacement zone is provided between the projection and the test tube in such a manner that the projection can be brought into contact with the test tube tip upon pressure on the tube end.
