Description:

The Livingstone Rubber Stopper with Two Holes (Item No. 7248-11A) is a versatile and essential laboratory accessory designed to securely seal test tubes, flasks, and other glassware while allowing controlled access for tubing or instrumentation. With dimensions of 29mm base diameter, 34mm top diameter, and 34mm height, this stopper fits snugly into standard lab containers, creating a tight seal that prevents chemical leaks, evaporation, and contamination.

Made from high-quality, chemical-resistant rubber, the stopper maintains flexibility and durability under repeated use and exposure to various reagents. The dual-hole configuration is ideal for setups requiring simultaneous insertion of glass tubing, thermometers, or gas delivery systems—making it a practical choice for distillation, filtration, and reaction experiments. Its tapered design ensures a secure fit, while the smooth surface allows for easy cleaning and reuse.

Packaged in sets of 10, this stopper is suitable for educational labs, research facilities, and industrial environments. Manufactured by Livingstone International—a trusted Australian-owned supplier of scientific and medical consumables—this product reflects a commitment to precision, safety, and long-term value in laboratory operations.
