Rubber Stopper with 1 Hole for Boiling Tube

A rubber stopper with 1 hole for boiling tubes is a versatile laboratory essential. This stopper is designed to fit snugly into the opening of a boiling tube, forming a tight seal that prevents spills and contamination during experiments. The single central hole allows you to insert thermometers, stirrers, or other lab equipment into the boiling tube while maintaining a closed system.

These stoppers are typically crafted from heat-resistant rubber, ensuring they can withstand the high temperatures encountered when boiling liquids. This makes them ideal for a wide range of laboratory applications, including:

• Chemical reactions: By creating a closed system, the stopper helps to prevent the escape of fumes or hazardous materials.
• Temperature monitoring: The hole allows for the insertion of a thermometer to accurately monitor the temperature of the boiling liquid.
• Mixing and stirring: Stirrers can be inserted through the hole to facilitate the mixing of solutions within the boiling tube.
