Products

At Xiamen Zhizi Industry & Trade Co., Ltd., we specialize in providing a comprehensive range of sample collection and laboratory consumables that meet the highest international standards. With years of experience in the medical and scientific supply industry, our company is committed to delivering innovative, reliable, and compliant products that support laboratories, hospitals, research institutes, and healthcare providers worldwide. Our product categories include saliva collection kits, extraction tubes, FOB tubes for fecal occult blood testing, general centrifuge and storage tubes, and other essential consumables for diagnostics and research.

Saliva Collection Kits

Our saliva collection kits are designed for non-invasive, convenient, and accurate sample collection. Certified with CE IVDR, FDA 510(k), NMPA, and ISO 13485, these kits guarantee compliance for global markets. Each kit ensures sample stability for up to 14–30 days, making them ideal for nucleic acid testing, genetic research, and clinical diagnostics. With a leak-proof design, sterilized packaging, and full traceability, our saliva collection kits provide laboratories and research organizations with safe and efficient solutions for large-scale sample collection. OEM and bulk customization options are available to meet the diverse requirements of international partners.

Extraction Tubes

We offer high-quality extraction tubes made from medical-grade polypropylene (PP) or polyethylene terephthalate (PET). Available in multiple sizes ranging from 0.5 mL to 50 mL, our extraction tubes are designed for efficient sample processing, including nucleic acid extraction, protein purification, and chemical separation. Resistant to chemical solvents and compatible with automated extraction systems, they ensure reliable performance across molecular biology, clinical testing, and pharmaceutical analysis. Each tube undergoes rigorous sterility and quality testing, guaranteeing high recovery rates and minimal sample loss.

FOB Tubes (Fecal Occult Blood Test Tubes)

Our FOB tubes are essential tools for colorectal cancer screening and fecal occult blood testing. With 18-month product stability, standardized sampling methods, and high compatibility with automated analyzers, these tubes help hospitals, diagnostic centers, and laboratories carry out accurate and efficient testing. Designed with patient and clinician convenience in mind, the FOB tubes minimize error risks while ensuring reliable test results. By providing bulk order options and full regulatory documentation, we support healthcare providers in improving early detection and preventive care programs.

Centrifuge and Storage Tubes

Conical centrifuge tubes and storage tubes are another core category in our product portfolio. With conical bottom designs, our centrifuge tubes allow efficient precipitation and easy recovery of sediments, making them suitable for cell separation, protein analysis, and molecular biology applications. Manufactured from durable high-strength PP or PE, they are resistant to high centrifugal forces and chemical solvents, ensuring reliability in demanding laboratory environments. Leak-proof caps and precision-molded designs prevent contamination and sample loss, supporting secure long-term sample storage.

Integrated Consumables for Laboratory and Clinical Applications

In addition to individual products, we provide integrated sample collection kits that include multiple consumables in one package. This reduces procurement complexity, shortens supply chains, and lowers the risk of incompatibility among different components. Our kits have been tested for compatibility with Siemens, Beckman, and other leading brands of laboratory equipment, enabling seamless workflows without additional calibration. By simplifying laboratory operations, we help clients save time, reduce labor costs, and improve testing accuracy.

Customization and OEM Services

At Xiamen Zhizi, we understand that different industries and research fields have specific requirements. To address this, we provide flexible customization services with fast turnaround times. Standard customization requests can be fulfilled within 7–10 days, with no extra mold fees and a low minimum order quantity starting from 500 sets. Whether hospitals require high-capacity tubes, research institutes need RNase-free tubes, or veterinary labs demand microtubes for animal samples, we deliver tailored solutions that support precise experimental needs.

Quality Assurance and Compliance

Quality and compliance are at the core of our operations. From raw material selection to finished product inspection, we implement a full life-cycle quality control system. All raw materials undergo sterility and pyrogen testing, production takes place in 100,000-class clean workshops with automated lines, and every batch is subject to random testing to verify leakage prevention, anticoagulant effectiveness, and puncture success rates above 98%. Post-delivery, we offer one-year traceability for all products and free returns within seven days in case of quality issues, ensuring zero risk for our clients.
