CF4 – Medium Grade Sample Pads

To ensure that your assay begins without complications, Cytiva offers a complete range of high-quality sample pad materials. CF4 is medium grade, suitable for use as a sample pad in lateral flow applications. Sample pads begin the assay by transporting samples from the point of application to the test components. CF4 can also be used as an absorbent sink at the downstream end of the test to control sample flow along the strip. Choosing an absorbent with sufficient capacity is an important consideration when designing an assay.
