CF-2 is a wet strengthened cellulose fibre for use in dipstick colorimetric assays.
- Wet-strengthened for easier handling during kit manufacture.
CF2 – Wet-Strengthened Sample Pads
CF2 contains an FDA-approved resin that binds the cellulose fibers together. This significantly increases the strength of the paper, especially when it is wet. Therefore, the use of the wet-strengthened grade reduces waste during manufacture due to the snapping of the cellulose during coating and also reduces the risk of the pad decomposing during use.Read more
Dipstick Colorimetric Assays
Sample pads begin the assay by transporting samples from the point of application to the test components. 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.Read less
