Porvair’s BioVyon is a high-performance porous polymeric material manufactured to the highest cleanliness standards.

This unique material, produced from high-density polyethylene resin using a proprietary process that can be modified, is activated and then formed into filtration media of different void volumes according to the target application. Of special note is the application of this material in chromatography. Used in filter and pipette tips, solid-phase extraction microplates and cartridges, BioVyon has found a niche with many blue-chip chromatography suppliers and manufacturers for the benefits it offers—particularly in demanding scientific applications. The co-sintered products are made using a solid-state media created from an ultra-pure and highly modified polymeric material with the lowest levels of extractables and leachates. Proprietary technology allows high-purity silica or DVB resins to be supported in a matrix that provides a high surface area, while reducing channeling through the column. As the porous material is co-sintered under high pressure and temperature with the polymer matrix, the resultant frit or column is impervious to further compression and easily resists channeling of liquids, even at high flow rates.
