That depends on the size, the type of glass, and if the test tube has an special features - such as threading at the top to allow a screw cap to be screwed on...
With that said, a typical price for the test tubes you usually see is around $1/each for a 14 ml Pyrex test tube. I've seen really cheap ones for less than half that when bought in bulk and some specialty ones that were over $5/each.

Why don't you heat a test tube continuously?
To avoid dangerous tension in the glass.
If a chemical reaction produces a gas how can that gas be captured in a test tube?
To capture a gas produced in a chemical reaction in a test tube, you can use a rubber stopper with a glass tube inserted into it. As the gas is produced, it displaces the liquid in the test tube and fills the space above. The glass tube allows for a controlled release of the gas when needed.
Why an empty test tube placed in water in a beaker with mouth outside the water surface shines like a mirror when seen at certain angle?
the test tube has air inside it.In the outer surface of the test tube is water.Due to the different media across the test tube surface the reflection of light occurs through the glass surface.Hence the test tube shines(behaves)like a mirror

A large test tube designed specifically for boiling liquids is called a boiling tube.
Why does the water plug in the glass tubing moves upward as temperature in the test tube increases?
As the temperature in the test tube increases, the air inside the test tube expands, leading to a decrease in pressure. This decrease in pressure causes the water plug in the glass tubing to move upward as it seeks to equalize the pressure inside and outside the test tube.
How expensive are science test tubes?
The cost of science test tubes can vary depending on the material, size, and quantity. On average, a pack of basic glass test tubes can range from $10 to $20. More specialized or larger test tubes made of materials like borosilicate glass or plastic may cost more.
Does blood clot in a glass test tube?
