To measure the depth of a test tube, you can use a ruler or caliper. A ruler can be placed alongside the test tube to read the depth directly, while a caliper can provide a more precise measurement by fitting snugly inside the tube. If the test tube is transparent, you could also use a water level to gauge the depth by marking the water level as it is filled.
200m long.
another name for test tube is culture tube or sample tube
It depends on what size test tube you are using.
If a test tube is clean and dry, then there should be nothing in it.
My best bet would be to heat the test tube to help evaporate the left over water. If for some reason it is a solid, that flush it out with water, then do the first step. The easiest way of drying test tubes would just be by turning it upside down in a test tube holder. Make sure you flush it out with distilled water though to get rid of any residues.
No, the tail of a vernier caliper is used to measure inside dimensions like holes or pipes, not depth. To measure the depth of the test tube, you would need to use the main scale and the vernier scale on the caliper's jaws.
You can use a ruler or a tape measure to measure the length of a test tube. Simply place the test tube on a flat surface and align the ruler or tape measure along its length to get an accurate measurement.
Test tube rack does not measure but supports tubes during titration or storage hence preventing them from damage.
Yes, of course you can ( if the tube is graduated. )

with a ruler
You would obtain a test tube, measure the mass of the test tube. Then add the NaCl to the test tube and measure the mass. Then subtract the mass of the test tube from the mass of the test tube+the NaCl to find the mass of the NaCl.
A small graduated test tube can measure ml.
As the inverted test tube is inserted into the measuring cylinder containing water, the water will rise up into the test tube due to atmospheric pressure. The level of water inside the test tube will stabilize at a certain height once the pressure inside and outside are balanced. This can be used to measure the volume of the test tube.
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 13 mm (about half an inch) in diameter and 100 mm (a bit under 4 inches) long.
that depends on the kind of test tube that you have. if a test tube is calibrated then it measures the volume of a liquid that is placed inside it. if the test tube is non calibrated then its meant for storage and mixing so it does not measure anything..
