Stopple

A stopple is a small, often tapered, plug or stopper, typically made of cork, rubber, plastic, or glass, used to seal the opening of a bottle, vial, or other container. Its primary function is to prevent the escape of contents, such as liquids or gases, while also protecting the contents from contamination by external factors like air or microorganisms. The design can vary, with some stopples designed to be easily removed and replaced, while others are meant for a more permanent seal. The choice of material depends on the intended use and the properties of the substance being contained.

Stopple meaning with examples

• The winemaker carefully inserted the cork stopple into the neck of the wine bottle, ensuring a tight seal to preserve the quality of the vintage. They used a special corking device to compress the stopple before inserting it, guaranteeing an airtight closure. Years of experience taught them when the stopple provided a reliable closure, so the wine can age well. Proper stopple insertion and removal is a key to preserving the quality of the beverage. Careful consideration of the **stopple's** quality is crucial in the art of winemaking.
• The pharmacist carefully selected a rubber stopple for the vial containing the sensitive medication. A tight fit was ensured, sealing the contents from atmospheric contact. To prepare for a new injection the stopple had to be removed. The **stopple's** resilience helped it contain and preserve the medication until use. Proper cleaning is a requisite element when dealing with a delicate stopple like this.
• After filling the test tubes with the chemical solution, the scientist quickly secured each with a glass stopple. It was important to have the seals complete on time so that each reaction remained contained and pure. The clear view through the stopple allowed observation of any changes within. Each vial's stopple served to prevent unwanted reaction and contamination. Careful work requires good equipment and a quality stopple.
• The lab technician meticulously examined the plastic stopple before using it to seal the sample container. The goal was to ensure no leakage or tampering. This stopple's durability allowed for transportation without spillage. With this stopple the sample will stay safe for transport. The integrity of the stopple affected the integrity of the work, and the technician knew that. It was all about securing that stopple and its seal.
• The chemist decided on a special, chemically inert stopple for the flask containing the reactive gases. This was crucial for preventing leakage and maintaining safety within the lab. The stopple choice could affect the outcome of their research. The gas would cause serious damage without a quality stopple. Choosing the right stopple was a critical part of the preparation. Each stopple played its role in safety and science.
