HOW VCN CLEANS SMALL LUMENS
Vapor Formation
In an enclosed vessel, the hydrostatic pressure exerted by the contained water corresponds to its vapor pressure. The headspace above the liquid is saturated with water vapor. When a vacuum is applied, water vapor is evacuated from the chamber. To restore equilibrium, water undergoes phase transition, forming vapor bubbles that replenish the vapor space.
Nucleation
Boiling liquids necessitate the presence of nucleation sites to initiate vapor phase formation. Vapor nucleation predominantly occurs at crevices and confined regions characterized by a high solid-to-liquid surface area-to-volume ratio. The interior surfaces of small lumen tubes serve as optimal sites for bubble nucleation. Vapor bubbles originate within the lumens, displacing liquid and inducing internal fluid dynamics. Reversal of the vacuum cycle results in re-condensation and the ingress of fresh fluid, continuing the procedure until the lumen is effectively cleaned.

The video demonstrates an internal cleaning technique for tubes, applicable when external cleaning is insufficient. This method effectively cleans from the interior of the tube outward.
