Silicone Reagent Bottle Stopper | Laboratory Sealing Plug
Premium Silicone Sealing Solution Designed for Laboratory Safety
Manufactured from high-quality heat-resistant silicone rubber, these stoppers deliver excellent elasticity and long-lasting sealing performance. Specially engineered for reagent bottles, sampling bottles, Erlenmeyer flasks, test tubes and other laboratory containers, they effectively prevent liquid leakage, reagent volatilization and external contamination—ensuring safe storage and reliable experimental results.
Key Advantages
Outstanding Durability: Acid-resistant, alkali-resistant, corrosion-resistant, and capable of withstanding high and low temperatures. Resistant to aging and reusable without deformation.
Reliable Seal: Tight fit to the bottle neck prevents evaporation and contamination, keeping samples stable.
Safe & Eco-Friendly: Non-toxic, odorless, and physiologically inert. Meets standard laboratory requirements.
Practical & Convenient: Compatible with various bottle sizes, easy to install, and suitable for routine disinfection processes.
