The transfer of liquid from one point to another via capillary forces
Capillary action moves a liquid throughout a material for a variety of applications. In fragrance delivery, pregnancy testing, and ink flow control, capillary structures can be optimized for highly regulated wicking capabilities. Porex Filtration Group's fluid transferring materials are customizable for specific liquid holding capacities, transfer rates and porosities, offering optimal scent diffusion, sample collection, ink extraction, and more.
Our customer needed a high-quality wick for lateral flow diagnostic tests that would alert the user to ideal sample saturation. We created highly pure sample collection media with proprietary color change technology – combining consistent wicking speeds with clear visual indications. Our solution offered a lateral flow diagnostic test with faster sample collection and more reliable, easier-to-interpret results.
