Greiner Bio-One Microplate Seal CapMat Square 384 Well Plates Lot of 20 Seals

Greiner Bio-One 384-Well Square Well CapMat Microplate Seals – Lot of 20

The Greiner Bio-One 384-Well CapMat is a reusable, high-performance sealing mat meticulously engineered for high-throughput screening (HTS), compound storage, and high-density assay incubation. Specially molded from high-purity elastomer compounds, this CapMat features 384 protruding square-profile plugs designed to match the specific internal diameters of Greiner 384 square-well microplates. Providing a robust, hermetic friction seal across every individual well, this lot of 20 seals minimizes sample evaporation and eliminates cross-well vapor migration during long-term storage or thermal incubation cycles.

Technical Performance & Design

• Precision Square Plug Profile: Engineered with 384 perfectly spaced square-profile plugs that sit snugly inside each well, creating a uniform mechanical compression barrier to isolate volatile liquids.
• Chemical & DMSO Vapor Resilience: Fabricated from high-grade elastomer materials that exhibit exceptional tolerance to aggressive organic solvents like Dimethyl Sulfoxide (DMSO), ethanol, and laboratory acids.
• Autoclave & Cryogenic Stability: Thermally stable composition allows the mats to withstand repetitive autoclave sterilization cycles at 121°C or withstand deep sub-zero containment inside cryogenic biobanks down to -20°C or -80°C depending on specific polymer cross-linking.
• Piercable Sealing Architecture: Designed with thin-gauge, pierceable plug centers that facilitate direct sampling via automated liquid handler needle arrays or robotic pipettors without forcing mat removal.

Key Benefits & Applications

• High-Throughput Screen (HTS) Storage: Acts as an absolute vapor barrier for automated compound library plates, preventing the absorption of atmospheric moisture by hygroscopic DMSO solutions.
• Thermal Incubation Protection: Prevents volume loss and meniscus distortion in low-volume amplification assays or long-term bacterial cell culture maturations.
• Eco-Friendly Cost Reduction: Unlike single-use adhesive foils or heat-sealing films, these durable mats can be repeatedly washed, sanitized, and autoclaved, drastically minimizing solid laboratory waste profiles.
• Automated Deck Compatibility: Aligns flush across the standard microplate perimeter flange, preventing robotic gripper arms or stackers from snagging or misaligning the plates during high-volume transfers.
