A Silicone Stopper is an essential sealing component in laboratories, offering a high-performance alternative to traditional rubber or cork stoppers. Designed for demanding scientific environments, silicone stoppers provide airtight, chemical-resistant, and temperature-tolerant seals across a wide range of lab applications.

  Sealing flasks, test tubes, and bottles in chemical and microbiological labs.

 Used with filtration flasks to create airtight connections for vacuum filtration systems.  As a pass-through stopper, can be drilled to accommodate glass tubes, pipettes, thermometers, or vacuum lines.

 Suitable for gas collection, fermentation setups, and anaerobic culture systems. Ideal for use with strong solvents or aggressive chemicals where rubber stoppers degrade.

·         Always check for proper sizing to ensure an airtight seal.

·         When drilling or inserting tubing, use a sharp, clean punch to avoid tearing.

·         Clean with mild detergent and rinse thoroughly before reuse.

·         Compatible with autoclave sterilization or dry heat sterilizers.

·         Solid Silicone Stoppers – For standard sealing.

·         One-Hole / Two-Hole Stoppers – Pre-drilled for tubing or sensors.

·         Customizable Hole Sizes – For specialized lab configurations.

·         Bulk Packs – For large institutions or laboratory facilities.
