Coated rubber stoppers come in various sizes and shapes to fit different applications. The most common shapes are cylindrical and tapered, with cylindrical stoppers being more commonly used. The following are the different sizes and shapes of coated rubber stoppers:
Cylindrical Stoppers: These stoppers are straight-walled and have a flat or rounded top. They are available in various diameters and lengths, with diameters ranging from 6 mm to 50 mm.
Tapered Stoppers: These stoppers have a conical shape, with the top end being smaller than the bottom end. They are available in various sizes, with the smallest diameter being around 3 mm and the largest being around 40 mm.
Lyophilization Stoppers: These stoppers are specifically designed for use in lyophilization, also known as freeze-drying. They have a special coating that prevents them from sticking to the vial during the drying process.
Serum Stoppers: These stoppers have a flared shape that allows for easy insertion and removal of syringes. They are commonly used in serum vials.
When choosing the right coated rubber stopper for your application, you need to consider the size of the vial, the type of solution to be stored, and the method of closure. The stopper should fit tightly enough to prevent leakage but not so tight that it is difficult to insert or remove. It is important to consult with a supplier or manufacturer to ensure you choose the correct stopper for your application.
