Test tube stands have a very simple use. They are used to hold test tubes during experiments to prevent them from falling over and spilling.
To hold test tubes. LOL
to hold the test tube
It can be held upright with a test tube stand or a retort stand.
a test tube rock is used to measure liquids
A retort stand is to hold a test tube/ boiling tube. 1. Turn the side knob( by the "t" on the retort stand) and release it. 2. Put the test tube/boiling tube in the test tube/boiling tube holder. 3. TIGHTEN the side knob ( if not the test tube/ boiling tube will drop). 4. Adjust the height of the retort stand by turining the most corner knob. (if you need to)
used to chemical test
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.
To hold your test tubes in, or to keep them upright.
A test tube holder or rack is used in a laboratory to hold or support test tubes containing chemicals or other contents awaiting further operations. Although it is called a test tube holder, it is also used to hold/support pipettes, etc. Since a test tube has a rounded bottom, it cannot stand by itself; the rack is a convenient and necessary piece of laboratory equipment for the storage of test tubes.
No. A ringstand is a stand with a base with a large pole sticking out of it. that you can attach rings to. A wire mesh is usually placed on the ring for setting a beaker to be heated. A test tube clamp can be attached to the ring stand to hold a test tube, for say, heating it in a hot water bath.
