Sample wicks transport samples from points of application to sequential
test components (e.g., a separate conjugate release pad or reaction
membrane where the capture line has been applied). Whatman offers a
complete range of high quality sample wick materials.
Features and Benefits
- Superior test-to-test reproducibility and reliability.
Ensure consistent absorbency and wicking rates
- No sample contamination.
Products are manufactured in controlled environments from the
highest quality raw materials
- Test sensitivity maintained.
Low- to moderate-protein binding transports samples to reaction
sites with minimal loss of sample analyte
- Inherently hydrophilic.
Facilitates easy absorption and wicking of aqueous samples
Product Range and Properties
CF1
100% cotton linter. Light, thin grade. Suitable for small sample
volumes.
CF3
100% cotton linter. Medium weight and thickness. Suitable for larger
sample volumes than CF1. CF4
100% cotton linter with acid treatment to improve wet strength and
reduce trace impurity content. Similar weight and thickness to CF3 with
faster wicking.
CF6
Glass fibre/cellulose mix. Heavier weight and thickness with high
absorbency for larger sample volumes.
Standard Sizes
Reels are available in the following standard sizes:
12mm x 50m
17mm x 50m
