ADVANTAGES

The dualtube biological sample collection kit contains two extraction cotton swabs, one red and one blue. It involves a two-step wiping process, with clear separation between dry and wet steps. The large - flat - surface design facilitates writing and eliminates the need for evidence bag packaging. The inside of the casing uses antistatic materials to prevent DNA adsorption, reducing the loss of trace evidence. The casing is equipped with a patented preservation solution device, which can effectively inhibit DNA degradation and improve the DNAdetection rate.

Integrates cotton swab, extraction solution, desiccant and storage box for easy portability.

Sampling: Take out the swab, dip in extraction solution, wipe bloodstain, seal - efficient and quick.

No need for multi - person cooperation; one can complete the whole sampling process alone.

Convenient and fast, no need to wait for natural drying, greatly reducing the possibility of DNA contamination.
