Rubber Stoppers

Rubber stoppers, also known as rubber plugs, are cylindrical or conical-shaped rubber pieces used to seal the openings of laboratory equipment, medical devices, and other containers. They are typically made of natural rubber, synthetic rubber, or silicone, which are flexible and resistant to temperature changes, chemicals, and abrasion.Rubber stoppers are commonly used in laboratories to seal test tubes, flasks, and other glassware to prevent spillage or contamination. They can also be used in medical devices, such as syringes, to seal the openings and maintain the sterility of the device. Rubber stoppers are also used in a variety of industries, such as pharmaceuticals, food and beverage, and chemical manufacturing, to seal containers and prevent the contents from leaking or spilling.Rubber stoppers come in a range of sizes and shapes to fit different types of openings. They can be tapered, straight-sided, or have a flange or lip that extends beyond the opening. Some rubber stoppers may also have a hole in the center to allow for the insertion of a pipette or other instrument.
