High-quality Silicone Caps for Vials



Product Description

This is a Silicone Cap for Vials in the medical industry. It’s completely black. It has a cylindrical rubber cap structure. Its surface is smooth and uniform. It has the soft texture unique to silicone materials.The top of the cap is designed with a cross-shaped incision. Its edges are regular. It has a hollow cylindrical inner wall. This lets it fit accurately over the mouth of vials. Its overall dimensions are precise. Its shape is uniform. It’s used to seal vials. It ensures the cleanliness and stability of samples inside the vials. It’s a practical sealing component in laboratories or the pharmaceutical field.It’s a specialized sealing product for medical and laboratory containers. It’s an important part of In Vitro Diagnostic (IVD) Equipment Accessories and IVD Seals. It meets the hygiene and precision standards of Medical Silicone Seal and Medical Vial Cap Seals.

Product Features

1. Function:Silicone Caps for Vials are mainly used to seal vials. They can fit tightly over the mouth of vials.They prevent leakage of samples inside the vials (such as reagents, biological samples, chemical reagents). This ensures the integrity of the samples. They also block the invasion of external dust, moisture, and microorganisms. This maintains the cleanliness and stability of the samples.They are suitable for scenarios such as laboratory sample storage and pharmaceutical reagent packaging. Their sealing function matches the protective requirements of Sterile Medical Seals and Diagnostic Device Gaskets in medical and laboratory systems.

2. Performance Characteristics

1)Reliable Sealing PerformanceSilicone material has high elasticity. This lets it fit tightly with the mouth of vials. It forms an effective seal. It prevents sample leakage and external contamination. This ensures the purity and effectiveness of the samples. This performance meets the strict standards of Medical Grade Silicone Seals and Medical Vial Cap Seals.

2)BiocompatibilityIt’s made of medical-grade silicone. It works well with biological samples, pharmaceutical reagents, and other substances. No harmful substances are precipitated. It won’t contaminate samples. This meets the biosafety requirements of laboratories and the pharmaceutical field. This biocompatibility matches the safety specifications of medical silicone seal and Sterile Medical Seals for biological contact.

3)Strong Temperature ResistanceIt can adapt to a wide temperature range (-60℃~200℃). It meets various working conditions such as sample cryogenic storage and high-temperature sterilization. After temperature changes, it still maintains good elasticity and sealing performance. This temperature adaptability meets the durability requirements of Freezer Tube Seals and temperature-resistant medical sealing components.

4)Chemical Corrosion ResistanceIt can stand the erosion of various media. Such as acids, alkalis, organic solvents, and biological reagents. After long-term contact, it won’t swell or age. It maintains stable performance. It’s suitable for the packaging of various samples. This corrosion resistance meets the standards of IVD Seals and medical sealing components in complex chemical environments.

5)Good Elasticity and Deformation RecoverySilicone has high elasticity. This lets it change shape moderately when fitted over the vial mouth. It fits tightly to the mouth. After deformation, it can quickly return to its original shape. Even after multiple uses, it still maintains sealing performance. This elastic performance matches the dynamic requirements of Diagnostic Device Gaskets and flexible medical sealing parts.

6)Practicality of Incision DesignThe cross-shaped incision on the top makes it easy for sampling tools (such as needles) to puncture. After sampling, the incision can rebound and close. This achieves sealing again. It ensures the continuous storage stability of samples. This practical design matches the functional requirements of Reagent Container Lids and laboratory sample sealing accessories.
