Sample Collection and Preservation Tube KJ535 (CAT#: STEM-BC-1082-ZJF)

The KJ535 sample collection and preservation tube is a disposable diagnostic consumable designed for the collection, preservation, and transport of biological specimens for downstream molecular or microbiological testing. It incorporates a pre-filled proprietary preservation buffer that stabilizes nucleic acids (DNA and RNA), proteins, or microorganisms at ambient temperature for extended transit without requiring cold-chain infrastructure. The tube is used for the collection of saliva, oral swab, urine, feces, nasopharyngeal swab, and other specimen types for nucleic acid extraction and PCR-based diagnostic assays. The collection funnel or swab interface is designed for direct specimen delivery into the preservation buffer, minimizing the steps between collection and sample inactivation. Viral transport tube variants support inactivation-compatible collection for respiratory viruses including SARS-CoV-2 and influenza, enabling safe handling of specimens without biosafety level 3 containment. The tube body is manufactured from polypropylene (PP) with a leak-proof screw cap or press-fit closure to ensure biosafe containment during transport in clinical and field settings. Graduated volume markings on the tube surface allow visual assessment of specimen volume and buffer dilution ratio for quality control purposes. The product is manufactured under Quality Management Standard 13485-compliant quality management and validated to demonstrate nucleic acid stability over defined temperature and time conditions. 2D barcode-labeled variants support direct LIS integration, enabling electronic chain-of-custody management from collection to result reporting. It is suitable for use in hospital infectious disease departments, public health laboratories, community screening programs, and field epidemiology applications.
