Our saliva collection screw top tubes are manufactured with care as the medical sector requires. They are specifically designed for saliva sample collection, making them ideal for a variety of diagnostic tests. These are especially helpful in genomic studies, drug testing, and other medical practices that require saliva as a specimen. The evaporating residue is irreversibly bound in the sealed sample so sample loss and specimen contamination is avoided, which are vital for accurate diagnostic testing. We are steadfast in our commitment to high standards of security and quality, and promote active health management practices in sync with the Healthy China campaign.
