Recommended for the production of test strips by impregnation with specific reagents via roll-to-roll or via dipping of sheets.
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.
