A hollow glass stopper is a type of laboratory glassware used to close and seal a container, such as a flask or a bottle. It is made of glass and has a hollow center, which allows for the insertion of a thermometer, stirrer, or other laboratory tools.

The stopper is inserted into the container to create an airtight seal, which is necessary for many chemical experiments where air or moisture must be excluded.

The glass material provides a durable and chemically resistant seal, making it a reliable choice for laboratory use. The stopper is available in a range of sizes to accommodate different neck sizes of containers. The hollow design of the stopper allows for versatility in use, making it a common choice in laboratory settings.
