Like the function of a beaker; to hold chemicals
A test tube is another useful science equipment used in experiments. A test tube is used:-
1. to carry solids or liquids in small quantity.
2. to do experiments, such as knowing the nature of the substance poured in it( acidic, basic or neutral) .
basically, test tube's function is to carry substances in science labs.
The function of test tubes is to provide a controlled environment for what ever you are doing inside the test tube. Most are used for chemical reaction because the glass test tubes are made out of can withstand thousands of degrees before melting.
A test tube holder is a small tool used in chemistry and in labs. A test tube holder is basically a holder or clamp.
A test tube holder has one job; to hold test tubes. A test tube holder's job is to be able to hold test tubes firmly without it slipping and/or cracking or breaking. It's main use though is to carry test tubes when they are very hot.
A test tube holder is used to hold a test tube when it is hot.
testube holder is the tube that you test with a holder
A test tube is designed to contain reactions involving small amounts of substances.
test-tube holde is use to hold/support test tubes containing chemicals
waiting for further operations
The function of test tube holder in the laboratory is to support these test tubes.
it is use to hold the test tube
If you are heating a test tube, point it away from yourself and others. If you need to place a test tube into a hot water bath, or take it out of a hot water bath, you need to use a test tube holder and not your unprotected fingers. Do not leave the test tube holder attached to the test tube while it is heating, as this will also heat up the test tube holder. If a test tube breaks, tell your teacher, and clean it up with a broom and dust pan. Don't pick the glass up with your fingers.

A culture tube or sample tube.
Test tube brush=use for cleaning 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.
use to hold test tube..

Very simple, place the test tubes in the holder.
When heating a test tube, you would use a test tube holder. It can also be used to hold/ support pipettes, etc. http://www.answers.com/mt/test-tube-holder
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).

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!
