The primary function of the extraction buffer tube in self-test kit products is to pretreat and extract samples, ensuring effective detection of target substances. Typically, the user puts the sample into the extraction buffer tube, and by shaking or squeezing, the sample is fully mixed with the buffer, thereby destroying the cell wall or virus shell in the sample, releasing the target material for subsequent detection.
In short, the plastic extraction tube is essential in self-test paper products, enhancing test accuracy, convenience, and safety.
