Tongs are made of metal and look like large sized tweezers. Used to turn over burgers on the barbecue or other tasks where grasping something while not using your hands is the desired result.
Test tubes are made of glass and are look like slender beakers. Generally used in scientific laboratories.

Tongs are likely to be used to pick up and hold items ranging from sugar lumps, small lumps of coal (non dangerous); contaminated or toxic material, test-tubes over a bunsen-burner's flame (possibly dangerous). If possibly dangerous, wear safety glasses, gloves and an apron.

Tongs
Most Chemistry labs have tongs that allow you to grip or hold small test tubes so you will not burn your hand or spill harmful chemicals on your fingers. They are usually simple metal tongs that are flat but the ends are curved to the radius of the test tube.
Test tube tongs are specialized tools used in laboratories to safely hold and manipulate test tubes. They typically have rubber or plastic coated tips to provide a secure grip without damaging the glass. Test tube tongs help prevent accidents and protect the user from chemicals or heat during experiments.
A test tube holder is a laboratory tool used to hold test tubes securely while heating them over a Bunsen burner or other heat source. It is designed with insulated handles to safely grip hot test tubes and prevent burns or accidents. Test tube holders allow for efficient and controlled heating of the contents inside the test tube.
Because sometimes in a lab,you use different and dangerous type chemicals so if for example,You pour a very chemical that uyou can't touch the test-tube and then you have to use the Tongs just so that you could be safe so I think that it is safe and the best idea to have tongs kept near the top of the test-tubes
Skidding tongs are used to grip and lift logs for skidding or dragging purposes. To use them, attach the tongs securely to the log using a chain or cable. Make sure the tongs are firmly clamped onto the log before attempting to lift or move it using a skidder or winch.

A test tube holder or flask tongs are commonly used in laboratories to safely hold test tubes or flasks during experiments. They have two long arms hinged together, providing a secure grip and keeping the user at a safe distance from chemicals or heat.

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.
If the test tubes need to be sterile, you would have to autoclave them.
