Product Introduction
- Product Overview: The Nucleic Acid Sampling Tube developed by Xiamen Zhizi Industry & Trade Co., Ltd. is a professional medical device designed for collecting and preserving nucleic acid samples (such as RNA/DNA from viruses or bacteria). It is widely used in infectious disease detection (e.g., COVID-19, influenza), clinical diagnosis, and epidemiological surveys. This Nucleic Acid Sampling Tube integrates sample collection, preservation, and transportation functions, replacing the traditional separate "swab + tube + reagent" combination. It is favored by medical institutions and testing laboratories for its high stability, safety, and ease of use, providing a reliable solution for accurate nucleic acid detection.
- Product Performance: The Nucleic Acid Sampling Tube excels in sample preservation and compatibility. Its pre-filled virus preservation solution contains guanidine salts and RNase inhibitors, which can inactivate viruses within 10 minutes and prevent nucleic acid degradation—samples remain stable for 72 hours at 2-30℃ with a detection rate of over 98%. Made of high-transparency medical-grade PET material (light transmittance 92%), it has no nucleic acid adsorption, avoiding false negatives. It is directly compatible with fluorescent quantitative PCR instruments and automated extraction systems (e.g., Qiagen, Thermo Fisher), eliminating the need for sample transfer and reducing human error. Additionally, it passes a 1.5MPa water pressure test without leakage, ensuring safe transportation and storage.
2. Product Advantages
- Long-Term Nucleic Acid Preservation Design for Accurate Detection: The Nucleic Acid Sampling Tube integrates an innovative "dual-protection system". Firstly, it is pre-filled with a dedicated virus preservation solution containing core components like guanidine salts and RNase inhibitors. This solution can inactivate 99.9% of viruses within 10 minutes while inhibiting nuclease activity to prevent RNA/DNA degradation. Experimental verification shows that samples stored in this Nucleic Acid Sampling Tube remain stable for 72 hours at 2-30℃, with a nucleic acid detection rate of over 98%. Secondly, the tube body is made of high-transparency medical-grade PET material with a light transmittance of 92% and no nucleic acid adsorption. This avoids false negatives caused by material adsorption of samples and allows direct adaptation to the optical detection channel of fluorescent quantitative PCR instruments, eliminating sample transfer and reducing human error—providing a reliable sample guarantee for accurate detection of viruses such as COVID-19 and influenza.
- Integrated Operation Design to Improve Sampling Efficiency: Addressing the drawbacks of traditional sampling tubes (cumbersome multi-step operations of "sampling - capping - adding liquid" and high contamination risk), the Nucleic Acid Sampling Tube innovatively adopts an "integrated sampling-preservation" structure. The tube cap has a built-in sterile sampling swab with a precisely calibrated 15cm rod length, enabling easy access to the throat/nasal cavity for sampling. The swab tip is made of flocked material (500 fibers/mm²), increasing sampling volume by 40% compared to traditional cotton swabs. After sampling, simply break the swab into the tube and tighten the cap to complete sample preservation—no additional preservation solution is needed. The entire operation takes only 20 seconds, reducing time by 70% compared to traditional processes. Moreover, the cap features an "anti-slip corrugated design", allowing medical staff to tighten it easily even with gloves, making it suitable for high-frequency sampling scenarios like large-scale nucleic acid screening.
- Multiple Leak-Proof and Biosafety Protection to Reduce Infection Risk: The Nucleic Acid Sampling Tube achieves dual upgrades in safety protection. Firstly, the tube body and cap use a "triple-seal structure" (spiral seal, silicone gasket, leak-proof buckle), which can withstand a 1.5MPa water pressure test without leakage. Even during -20℃ freezing storage or 5000rpm centrifugation, it prevents sample leakage. Secondly, the cap has a built-in "anti-splash diaphragm" that blocks aerosol escape when opening the cap, avoiding medical staff inhaling virus-containing aerosols and complying with the secondary biosafety protection requirements in the Medical Institution Biosafety Manual. Additionally, the entire Nucleic Acid Sampling Tube is sterilized by ethylene oxide (residue <10μg/g), with no cytotoxicity or sensitization, enabling direct contact with human mucous membranes and ensuring the safety of medical staff and subjects during sampling.
- Full-Scenario Adaptation Design to Meet Diverse Needs: The Nucleic Acid Sampling Tube has "multi-specification + wide compatibility" features to adapt to different detection scenarios. Firstly, it offers three capacity specifications: 1mL, 3mL, and 5mL. The 1mL model is suitable for single-person testing, while the 5mL model supports pooled testing (10-in-1/20-in-1), meeting the needs of community screening, hospital visits, and port quarantine with different sample volumes. Secondly, the tube body is marked with clear "scale lines + sample information area". The scale accuracy is ±0.1mL, facilitating precise control of preservation solution dosage; the information area allows direct marking of sampling time, name, and serial number with a marker pen to avoid sample confusion. Thirdly, it is compatible with mainstream testing equipment—whether for manual nucleic acid extraction or automated extractors (e.g., Qiagen, Thermo Fisher), the Nucleic Acid Sampling Tube can be directly adapted without replacing consumables. Meanwhile, its 12mm standard tube diameter matches the hole size of test tube racks in nucleic acid testing laboratories, enabling batch storage and management and improving overall laboratory workflow efficiency.

During long-distance transportation of samples, the Nucleic Acid Sampling Tube maintains sample stability. In port quarantine, the Nucleic Acid Sampling Tube is indispensable, and the Nucleic Acid Sampling Tube helps block the cross-border spread of infectious diseases.
4. Frequently Asked Questions
- Q: How long can samples be stored in the Nucleic Acid Sampling Tube?
A: Samples can remain stable for 72 hours at 2-30℃ in the Nucleic Acid Sampling Tube. For longer storage (over 72 hours), it is recommended to store the Nucleic Acid Sampling Tube at -20℃, which can extend sample stability to 30 days without affecting detection results.
