Though they come in various sizes, test tubes are simply glass tubes. A graduated cylinder, however, has approximate measurements for varying volumes of liquid.
A sample tube, culture tube, sometimes a boiling tube.
With most liquids, the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. So the liquid "sticks" to the side of the container. A few liquids have a "backwards" meniscus. An example is mercury. If you put mercury in a test tube, it would be higher in the middle than at the edges.
The capacity of a graduated cylinder can vary depending on its size. Common sizes include 10 mL, 25 mL, 50 mL, 100 mL, and 250 mL. It is important to check the markings on the cylinder to determine its specific capacity.
A micropipette would be the best instrument for accurately dispensing 4 mL of hydrochloric acid into each test tube. Alternatively, a graduated cylinder with a precise scale could also be used.
Gases that are relatively insoluble in water are collected by water displacement. The gas pushes the water down and out of the water-filled gas-collecting vessel. The gas-collecting vessel (generally a flask or test tube) is first filled with water, covered with a glass plate or plastic wrap (no air bubbles must enter the vessel, and then inverted into a deep pan or tray half-filled with water. The glass plate or plastic wrap is removed, and the tubing from the gas generator is inserted into the mouth of the gas-collecting vessel.
Use a borosilicate glass graduated cylinder when applying heat, as it can withstand higher temperatures without breaking or shattering. Avoid using plastic graduated cylinders as they may melt when exposed to heat.
A graduated cylinder brush is a specialized cleaning tool designed to clean the inside of graduated cylinders, which are narrow and tall laboratory glassware used for measuring liquid volumes. The brush has a long handle and bristles that are flexible enough to reach the bottom of the cylinder to remove residues and contaminants. It helps maintain the accuracy and cleanliness of the cylinder for precise measurements.

what is the difference between proffiency and diagnostic test
A graduated cylinder is commonly used to measure and transfer liquids accurately. It has volume markings along its length, allowing for precise measurements. Additionally, a pipette is often used to transfer specific volumes of liquids from one container to another.
The difference between a test and a demonstration is that a test is to be taken and answered and a demonstration is to be demonstrated and be told to the class
A sample tube, culture tube, sometimes a boiling tube.
Can you tell the difference between Vyvanse and Concerta in a drug test
There is lot of difference between test flight/air test/first flight.
A water displacement test. You take a graduated cylinder full of water and read how many mL you have. Then you place the object in the graduated cylinder and read how much the water has risen. You subtract your first value from the value with the object in the cylinder. The amount you then come up with is the area in mL. This can be converted to cm cubed since they are equal.
what is the difference between in bone marrow and FISH test in chronic myloid leukemias
As a chemist I can tell you that there are a significant purpose differences between the two, though sometime masked in high school chemistry. In college you learn that the graduated cylinder are more specifically designed to measure volume of a liquid. The test tube is glass which is safer to do most chemical reactions in - meaning the test tube is not generally used for measurement but rather a container for liquids.
