• Ideal for the production of test strips by impregnation with specific reagents via roll-to-roll or via dipping of sheets.
• Made from ultrapure cotton linters and cellulose, entirely without any additives to ensure that no interference will occur with the reagents and their detection reaction.
• Tested specifically like chromatographic and blotting papers to ensure high and uniform capillary actions and a homogenous dispersion of the impregnation solution.
• High consistency in thickness and capillary force over the whole paper roll and from lot to lot.
• High wet strength for safe handling during reel-to-reel impregnation
