The disposable pipette's primary role in self-test paper products is to accurately and easily absorb and transfer liquid samples, such as blood, urine, or saliva, ensuring the accuracy of test results. Using pipette droppers simplifies the sample handling process and reduces the risk of contamination.

Advantages include:

1. Health and Safety: Single-use design prevents cross-contamination and germ spread, ensuring user safety.

2. Precise Control: The pipette's accurate design allows for precise control over the volume of liquid absorbed and released, enhancing test reliability.

3. Easy Operation: No professional training required, users can easily operate the pipette, making it ideal for home self-testing and increasing the product's convenience and accessibility.

4. Low Cost: Low production cost makes it suitable for large-scale use, making it economical.
