To hold your test tubes in, or to keep them upright.
A test tube rack is used to hold up test tubes. This is so they do not tip over and spill what is in them.
It is not recommended to place a hot test tube directly into a test tube rack as this can cause damage to both the test tube and the rack. It is advised to allow the test tube to cool down before placing it in the rack to prevent any accidents or mishaps.

I think the test tube rack is used to hold any amount of chemical or liquid during an experiment.
Test tube rack does not measure but supports tubes during titration or storage hence preventing them from damage.
Test tube racks are used to support the test tubes but unlike the test tube holder, it can store the test tubes without anyone who will hold the rack... hope this helps!
