FIELD: chemistry.
SUBSTANCE: test tube holder is made from a single plate which is bent to form a top supporting base with holes under the test tube, a bottom supporting base and posts connecting said bases. There is a single through groove in the plate for holding one of the test tubes in the required position during a chemical experiment. The groove consists of two sections. One of the sections is in the top supporting base and the other is in the post.
