HOW VCN CLEANS SMALL LUMENS
Vapor Formation
Water in an enclosed container will exert a pressure equal to its vapor pressure. The space above the liquid level is filled with water vapor. When a vacuum is applied to the chamber, vapor is removed. The vapor space now needs to be replenished. The water forms vapor bubbles that replenish the vapor space.
Nucleation
Boiling liquids require nucleation points to begin vapor formation. Vapor therefore begins forming on parts within the chamber. The best nucleation points are in crevices and tight areas where a high solid-to-liquid surface area-to-volume ratio is found. The interior of small lumen tubes is an ideal location for vapor bubble formation. The vapor bubbles begin to form throughout the lumens, and liquid is forced from the interior, creating fluid motion within the tube. Stopping the vacuum reverses the process, and fresh fluid enters the tube. This process is cycled until the tube is cleaned.
VIDEO: PROCESS FOR CLEANING SMALL TUBES
The video shows a method for cleaning tubes when just cleaning the outside of a tube is not an option. This method actually cleans from the inside of the tube outward.
