Silicon Cork ( Size: No #8 )

Silicon Corks are versatile, high-performance stoppers designed to securely seal flasks, test tubes, and other glassware in laboratory settings. Made from premium-grade silicone, these corks offer excellent chemical resistance, thermal stability, and a non-reactive surface, making them ideal for both general and specialized lab work. Unlike traditional cork or rubber stoppers, silicon corks are durable, flexible, and reusable. They can withstand a wide temperature range, making them suitable for use in autoclaves, ovens, and freezers. Their non-stick, easy-to-clean surface ensures contamination-free sealing and effortless handling.
