The principal scope is to realize chemical reactions on a very small scale. Also: storing liquid or solid substances, solubility experiments, etc.
A test tube is a cylindrical tube, made from plastics, glass, ceramics with a rounded closed end.
A test tube rack is a piece of laboratory equipment used to hold and organize test tubes. It typically has openings where test tubes can be inserted securely in an upright position. Test tube racks are used to store, transport, or organize test tubes during experiments and laboratory work.
According to the American Heritage Dictionary of the English Language, a test tube is a "clear, cylindrical glass tube usually open at one end and rounded at the other, used in laboratory experimentation."A test tube can be used to store chemicals that are dangerous to skin,or be connected to other lab equipment for experiments. In this case, it is usually to collect a useful product.
Test tube racks are typically made of metal, plastic, or wood to hold test tubes in place and keep them organized during experiments or storage. They come in various sizes and configurations to accommodate different numbers and sizes of test tubes. The material used depends on the desired durability, chemical resistance, and safety requirements of the laboratory setting.
A test-tube holder, also known as test-tube clamp or test-tube rack, is used to hold a test tube over a Bunsen burner during heating. It is designed to ensure safe handling and prevent accidents while working with test tubes and heat sources.
A purple or lavender-colored top tube with EDTA anticoagulant is typically used for collecting samples for a shingles test.

Test Tube brushes are used to easily clean the test tubes .
use to hold test tube..
A test tube holder, also known as test tube clamp or test tube rack, is used to hold a test tube in place when the tube is hot or should not be touched. It allows safe handling of test tubes during heating or when conducting chemical reactions.
A red tube with no anticoagulant is typically used for an AFP test.
A test tube cleaner is used as suggested -- it is used to clean test tubes. It is round, and has a modestly long handle so the bristles can reach the bottom of the test tube being cleaned.
used to place the test tube . :D hahaha
The color of the tube that is most often used for hematology CBC tests are
A test tube holder or test tube clamp is used to hold a test tube when heating it over a Bunsen burner. The holder provides a safe way to hold the test tube without the risk of burning yourself.
