Well when you are doing scientific experiments with test tubes you may put different substances or whatever you're using in different tubes therefore to separate them and study them individually...
Does that help you at all?
There are several uses for test tubes in a lab. In chemistry test tubes can be use for mixing or heating chemicals. In Biology test tubes may be used to keep various samples separate from each other. How the tubes are used depends on the science using them.
- to realize a chemical reaction
- to store for short time a reagent
To hold test tubes. LOL
when was test tube first made,when and who?
test tube is classified in to various types namely hard test tube ,boiler test tube,20 ml test tube
the test tube was half full in 10hrs 20min
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.
a test tube rock is used to measure liquids
used to chemical test
To hold test tubes. LOL
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.
Test tube brush=use for cleaning test tubes
Chemists, biologists.
used to hold small amounts of solution.
A test tube brush is a brush that cleans up your test tube when it is wet or messy.A test tube brush is used to easily clean the inside of a test tube.A test tube brush is a couple of wires spun together with bristles on one end in the shape of a test tube. They come in all different sizes and materials for all different size test tubes and uses.
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.
A test tube holder is a device to ...wait for it...hold test tubes ! ;-) Usually a rack or clamp that keeps them upright (& full if in use).
It depends on what size test tube you are using.
