This is a Sampling Port Cover for in vitro diagnostic (IVD) equipment. It is made of silicone. Its hardness is 60±5°A. It features a translucent appearance.It has an elliptical cap-shaped main structure. There is a concave elliptical area in the center of the cover surface. A raised sealing lip encircles the edge. This lip is designed to enhance fitting tightness with the sampling port. A small rectangular pull tab extends integrally from one side of the main body. The tab facilitates manual pick-and-place operations.As a dedicated sealing component for IVD systems, it complies with the rigorous standards of Medical Device Seals and Medical Grade Silicone Seals. It is fully compatible with the application requirements of In Vitro Diagnostic (IVD) Equipment Accessories and IVD Seals.
1. Functions
1)Sealing the Sampling Port & Isolating ContaminationIt fits tightly with the sampling port of IVD equipment. It blocks external contaminants such as dust and microorganisms from entering the sampling channel/reagent chamber. This prevents contamination of samples and detection reagents. It ensures the accuracy of in vitro diagnostic results. It also inhibits the volatilization of reagents (e.g., buffer solutions, enzyme reagents) inside the sampling port. It maintains stable reagent concentrations. This sealing performance meets the strict demands of Sterile Medical Seals and Diagnostic Device Gaskets for precision IVD workflows.
2)Assisting Convenient OperationThe rectangular pull tab design on one side allows laboratory personnel to open and close the cover quickly by hand. It adapts to high-frequency sampling scenarios in IVD labs. It improves operational efficiency.
Protecting Reagents & SamplesThrough the physical isolation of silicone material, it reduces contact between reagents inside the sampling port and the external environment. It lowers the risk of reagent oxidation and deterioration. It also prevents cross-contamination caused by sample exposure.
2. Performance Characteristics
1)60±5°A Hardness Balances Sealing and Structural StabilityThe medium-hardness silicone retains sufficient elasticity. It allows the edge sealing lip to fit tightly into micro-gaps of the sampling port for reliable sealing. It also maintains structural rigidity. It prevents deformation of the cover due to extrusion and frequent opening/closing. It ensures long-term stable compatibility with sampling port dimensions.
2)Silicone Material Resists Corrosion by Diagnostic ReagentsSilicone boasts excellent chemical resistance. It withstands various reagents commonly used in in vitro diagnostics (such as acid-base buffers, protein-based reagents, nucleic acid extraction reagents, etc.). Long-term contact will not cause swelling, stickiness, or material degradation. It avoids sample/reagent contamination due to material failure. This material property aligns with the standards of medical silicone seal and Reagent Container Lids for IVD applications.
3)Strong Structural AdaptabilityThe elliptical cap design with a surrounding sealing lip precisely matches common specifications of sampling ports on IVD equipment. It provides ample sealing area. The pull tab is integrally molded with the main body. It ensures firm connection and resistance to breakage. It is suitable for high-frequency opening/closing requirements.
4)Clean-Grade Material Meets IVD RequirementsThe silicone material releases no harmful substances. It complies with cleanliness requirements for in vitro diagnostic scenarios. It will not introduce impurities into samples/reagents. It guarantees the reliability of test results.
3. Application Scenarios
1)Various IVD EquipmentIt is suitable for sampling ports of biochemistry analyzers, chemiluminescence immunoassays, PCR amplifiers, nucleic acid extractors, and other in vitro diagnostic devices. It is a dedicated matching component for sampling procedures in clinical testing and scientific research experiments.
2)IVD Laboratory SettingsIt is ideal for hospital clinical laboratories, third-party medical testing institutions, biological research labs, etc. It is particularly suitable for high-throughput, high-frequency sampling workflows in automated/semi-automated in vitro diagnostic systems.
4. Pain Point Solutions
1)Solving the Problem of Poor Sampling Port SealingOrdinary sampling port covers tend to cause contamination or reagent volatilization due to loose fitting. It affects the accuracy of test results. The surrounding sealing lip and elastic silicone material of this cover achieve reliable sealing of the sampling port. It eliminates the risks of contamination and volatilization.
2)Addressing Low Operational EfficiencySampling covers without auxiliary structures are inconvenient to open and close. It increases the operation time for laboratory personnel. The pull tab design of this cover makes opening and closing more convenient. It adapts to the high-efficiency operation requirements of IVD labs.
3)Resolving Material Incompatibility with ReagentsOrdinary plastic/low-quality rubber covers are prone to aging and deformation after long-term contact with diagnostic reagents. They require frequent replacement. This silicone material is resistant to reagent corrosion. It extends service life. It reduces the cost of consumable replacement and frequency of operation interruption.
4)Eliminating Impurity Contamination RisksCovers made of non-clean-grade materials may release impurities. They interfere with precision IVD tests (such as nucleic acid amplification, chemiluminescence reactions). This silicone material releases no impurities. It meets the high cleanliness requirements of IVD scenarios. It ensures the reliability of test results.
