Coated Rubber Stopper Manufacturers

A coated rubber stopper is a type of rubber stopper used in laboratory settings that has been coated with a material such as PTFE (polytetrafluoroethylene) or silicone. The coating helps to provide an airtight seal and can prevent the stopper from sticking to the glassware. Coated rubber stoppers are often used in applications where a high degree of chemical resistance is required.
Coated rubber stoppers are used in the pharmaceutical industry as closures for vials and bottles to maintain the sterility and stability of the contents. The coating on the stopper provides a barrier between the rubber and the drug product, reducing the risk of interaction and contamination.
The coating can be made of materials such as silicone or fluoropolymer, which are inert and have good chemical resistance. The coated rubber stoppers also come in different standard sizes, such as 13mm, 20mm, and 28mm, to fit the corresponding vial or bottle sizes.
To ensure the safety and effectiveness of the drug product, it is important to use coated rubber stoppers that comply with international standards, such as USP (United States Pharmacopeia) and EP (European Pharmacopoeia), which specify the requirements for the material, dimensions, and performance of the stoppers.
To maintain a coated rubber stopper, you should follow these steps:
Store the stopper in a cool and dry place, away from direct sunlight or heat.
Clean the stopper with a mild detergent solution and rinse it thoroughly with clean water.
Dry the stopper completely before use or storage.
Inspect the stopper regularly for any signs of damage or deterioration, and replace it if necessary.
Avoid exposing the stopper to harsh chemicals or solvents, as this can damage the coating and compromise the integrity of the stopper.
Handle the stopper carefully to avoid puncturing or tearing the coating.
By following these guidelines, you can help to ensure that your coated rubber stopper remains in good condition and performs effectively over time.
