Sample Pad
The glassfiber sample pad is the part where the sample (urine, blood etc) is introduced to the test strip. It promotes even and controlled distribution of the sample onto the conjugate pad and prevents non-specific binding. Nupore GP-04 pads are available in standard thickness of 0.6mm.
Conjugate Pad
The conjugate pad is made of non-woven polyester and acts as a reservoir for detection conjugate. When sample flows into the conjugate pad, the conjugate moves from the pad to the sample and the 'conjugate-analyte' complex passes to the nitrocellulose membrane. Nupore PT conjugate pad has minimal additives so that user may include additives as per requirements.
Absorbent Pad
These are located at the downstream end of test and allows for increased volume of sample that can enter the test strip. These are hydrophilic in nature & have excellent absorbent capacity, and thus absorb the extra volume of sample. Type SP-08 are provided in customized length and width.
