EVA Polymer 96 Square Well Cap Mats

Manufactured in the United Kingdom from high-purity Ethylene Vinyl Acetate (EVA) or specialized polypropylene blends, these mats are robust enough for repeated use yet flexible enough to ensure a tight, uniform seal across all 96 wells simultaneously.

Features:

• Specifically molded for compatibility with popular 96-well square deep plates (including Cat. 219006, 219008, and 219009)
• Individual well-plugs prevent aerosol "cross-talk" between wells during transport or incubation
• Cat. 219019 is gamma-irradiated, making it ready for immediate use in sensitive microbiology or cell culture workflows
• Resistant to a wide range of laboratory reagents, including many organic solvents and aqueous buffers
• Designed to maintain seal integrity across a wide temperature range, from freezer storage to standard laboratory temperatures

Application Insight:

These mats are a cost-effective and reliable alternative to adhesive films, especially in high-throughput environments. Unlike films that can lose adhesion in cold or humid conditions, these friction-fit mats provide a mechanical seal that remains secure during centrifugation or vigorous shaking.

Pro Tip: To ensure an even seal across the entire plate, use a weighted roller or a manual plate press. This ensures every individual plug is fully seated into its corresponding well, preventing localized evaporation.
