Lateral flow absorbent pads
Customizable absorbent pads designed for Lateral Flow Immuno Assay applications guarantying the highest level of purity and quality.

Ahlstrom-Munksjö absorbent pads collect the liquid processed through the strip by capillary action, increasing consistency of the flow and preventing backflow of the liquid.

They are suitable for a wide range of diagnostics applications including:

  • Infectious disease screening
  • Pregnancy tests
  • Drug abuse monitoring
  • Veterinary diagnostics
  • Food and beverage testing
  • Environmental safety

The newly designed absorbent pad grade 440 offers an intermediate thickness and absorption capacity between our standard grades 222 and 270, exhibiting exceptional dimensional stability and a high wicking rate given to its consistency of a blend of cotton and glass fibers.

Our products are available in sheets and rolls in custom sizes.
