Selection guide – cellulose materials for dipstick colorimetric assays
January 01, 2024
Our range of cellulose materials offer 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 our quality manufacturing practices make these papers an excellent choice for large-scale manufacturing.

- Basic, single layer, dipstick assays are simple to use and require no sample prep or optical readout.
- Total assay response time is within minutes
- Very sensitive assays with as little as a few hundred microliters of sample liquid
- Easy to multiplex and commonly done in medical diagnostics
Resources
CF2 dipstick pads
A wet strengthened cellulose fiber for easy handling.
CF3 dipstick pads
Medium weight 100% cotton linter material (322 µm thickness at 53 kPA) with consistent absorbency and wicking rates.
CF4 dipstick pads
Medium weight, 100% cotton linter material (482 µm thickness at 53 kPA) with low protein binding.
CF6 dipstick pads
Thick, absorbent material (1450 µm thickness at 53 kPA) suitable for high sample volumes.
CF7 dipstick pads
Thick, 100% cotton linter material (1873 µm thickness at 53 kPA) for high sample volumes.
- Complex, multilayer or multiplexed dipstick assays require skilled users to administer the test and read results
- Requires a liquid sample such as urine, blood or water and is unlikely to convert solid samples to liquid
- Developmentally complex – multistep reactions require multiple pads that cascade into each other
- Stacked pad assays are tricky to read as the results show on the bottom of the pad which is adhered to plastic dipstick.
