Rubber Cork Two Hole

The Rubber Cork Two Hole, manufactured by Glass Agencies and supplied under the EROSE brand, is a laboratory accessory used for sealing flasks, bottles, and other laboratory vessels while allowing the passage of tubes, thermometers, or glass rods through two separate openings. This product is widely used in school laboratories, college science departments, research facilities, and training institutes where controlled transfer of gases or liquids is required during experiments. Made from high-quality rubber material, the cork provides flexibility and a secure fit within the necks of standard laboratory containers. The tapered shape ensures firm seating and helps maintain a tight seal, reducing the risk of leakage during experimental procedures. The two precisely formed holes allow simultaneous insertion of multiple laboratory components, supporting setups that require inlet and outlet tubing or combined measurement and transfer functions. The rubber construction allows easy insertion and removal of glass tubes without damaging the vessel or the cork itself. The cork is suitable for use with glass, plastic, and metal laboratory apparatus. Its surface finish supports easy cleaning after use, allowing repeated laboratory applications. The material maintains its form during routine laboratory conditions, supporting consistent performance across multiple experiments. This rubber cork is commonly used in gas generation assemblies, distillation setups, chemical reaction vessels, and demonstration apparatus. Glass Agencies follows controlled manufacturing and inspection processes to ensure uniform hole dimensions, proper tapering, and consistent material quality. The EROSE Rubber Cork Two Hole supports safe and organized laboratory experimentation by helping maintain sealed systems while allowing necessary connections. It is available in various sizes to match different vessel neck diameters and tubing requirements. With its practical design, ease of use, and reliable sealing capability, this product remains an essential laboratory component for educational, research, and training environments focused on controlled experimental setups.
