Corning Microplate Sealing Mat 96 Well Square Case of 50 Mats

Corning® 3083 96-Well Square-Well Sealing Mat (Silicone)

The Corning® 3083 is a high-performance, reusable sealing mat engineered specifically for 96-well square-well microplates and deep-well blocks. Manufactured from premium, medical-grade silicone, this mat provides an exceptionally secure, individual-well seal that prevents cross-contamination and sample evaporation. Its square-plug design is optimized to fit snugly into square-well geometries, ensuring a robust physical barrier even during high-force centrifugation or long-term storage. Designed for durability and chemical resistance, the 3083 is an essential consumable for laboratories performing high-throughput screening, compound library management, and genomic sample processing where high-integrity sealing is non-negotiable.

Technical Performance and Design

• High-Integrity Compression Seal: The silicone plugs are precision-molded to provide a tight friction fit within each well, maintaining a leak-proof seal across a wide range of temperatures and pressures.

• Superior Chemical Compatibility: The medical-grade silicone construction is highly resistant to common laboratory reagents and solvents, including DMSO, making it ideal for compound storage.

• Thermal Stability: Engineered to remain flexible and effective across a broad temperature spectrum, from ultra-low temperature freezers (-80°C) to autoclaving temperatures (+121°C).

• Reusable & Sustainable: Unlike single-use adhesive foils or films, these mats can be washed, sterilized (autoclaved), and reused multiple times without compromising sealing performance.

Key Benefits & Applications

• Deep-Well Block Sealing: The primary choice for sealing 1 ml or 2 ml square-well blocks during sample transport or orbital shaking.

• High-Speed Centrifugation: Provides the necessary mechanical strength to prevent well-to-well leakage during high-g pelleting or phase separation steps.

• Compound Library Storage: Specifically designed to minimize DMSO evaporation, preserving the concentration and integrity of stored chemical compounds.

• Sustainable Lab Practices: Reduces plastic waste by replacing single-use adhesive films with a durable, autoclavable sealing solution.
