This membrane is used for testing urine reactions and hepatitis B.

Sample pad is the platform where sample/analyte is placed at the testing stage. It is one of the most important elements after the Nitrocellulose membrane in the lateral flow test/immune chromatographic test.

The conjugate pad is made of a non-absorbent material such as fiberglass pad, polyester, rayon or other similar materials. It is composed of a synthetic material to ensure the efficient release of its contents.

The absorbent pad, also called a wick or wicking pad, pulls fluid off of the membrane to allow the capillary flow of the membrane to keep flowing in the proper direction and at the proper rate.
