Papers for Diagnostic Use

Recommended 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.

Absorbent materials for producing diagnostic tools as IVD’s have to meet very specific characteristics. The Hahnemühle absorbent media guarantee both, high and consistent performance. Purest available raw materials are used to produce this media and assure to get no cross contamination with the chemicals in the final test device.

Hahnemühle offer a variety of cellulose, cotton linters and glass fibre filters, that have been the first choice for device manufacturers of Lateral Flow and Flow Through assays, as well as dip sticks, such as a critical “Point of Care” urine test strips.
