CF7 – Thick Grade Sample Pads CF7 is a thick material suitable for high sample volume applications. It is particularly well- suited for use as an absorbent sink at the end of a lateral flow assay or at the bottom of a flow through assay kit. The increased water capacity of CF7 also makes it suitable for use in flow-through assays as an absorbent pad. Dipstick Colorimetric Assays As with other CF grades, CF7 is suitable for use in dipstick colorimetric assays. Dipstick colorimetric assays, in which a cellulose pad is impregnated with a color reagent, are widely used in everything from urine testing to environmental assays. The base cellulose is a key part of the system, and the correct choice of absorbency, wicking rate, and wet strength are critical to producing a working assay. The Cytiva range of cellulose materials for dipstick colorimetric assays offers highly consistent and inert substrates for absorption of the active chemicals required for development of dipstick tests. The purity of the cellulose base material, coupled with Cytiva quality manufacturing practices, make these papers an exceptional choice for large-scale manufacturing.
