capillary tubing
Học thuậtThân thiện
Definition
Noun: A very narrow tube with a small internal diameter. It is characterized by its ability to hold or draw in a liquid through the physical phenomenon of capillary action.
Usage
This term is used in scientific and technical contexts, particularly in physics, chemistry, engineering, and medicine, to describe a specific type of narrow conduit. It refers to the tube itself as an object or component.
Examples
- In the laboratory, capillary tubing is often used to collect small, precise samples of blood.
- The experiment demonstrated how water rises in capillary tubing due to adhesive and cohesive forces.
- The device uses a piece of glass capillary tubing to transfer the liquid reagent.
Advanced Usage
- The term is often used attributively (like an adjective) to specify the type of tube, as in "capillary tubing material" or "capillary tubing array."
- In chromatography, a capillary tubing column is a key component for separating chemical mixtures.
Variants and Related Words
- Capillary (noun): Often used synonymously with "capillary tubing," but can also refer specifically to the tiny blood vessels in biological organisms.
- Capillary tube: A common alternative term with the same meaning.
- Microtube: A more general term for a very small tube, which may or may not rely on capillary action.
Synonyms
- Capillary tube
- Microcapillary
- Fine-bore tube
Related Phrases
- Capillary action (or capillarity): The principle that explains how liquid moves through the tubing. This is the key functional concept associated with capillary tubing.
- Capillary flow: The movement of liquid within capillary tubing.
Noun
- a tube of small internal diameter; holds liquid by capillary action
