BRACKET CAP TUBE HOLDER

A bracket is a device that connects to a structure (such as a panel or frame) and is usually designed to support a vertical load or to strengthen an angle or to maintain a component in its proper position.

Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids in a thin tube. It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by cohesion within the liquid) and adhesive forces between the liquid and container wall act to propel the liquid.

A "holder" is a device or implement for holding, storing, or securing something. It may be a container or receptacle, a rack or rest, or even a bracket or screw.
