Thermo Scientific Microplate Sealing Mat 96 Well 8 mm 10 Plate Mats

Thermo Scientific 60180-M123 WebSeal Sealing Mat – 96-Well Square, 8mm, Pre-Slit Silicone

The Thermo Scientific 60180-M123 (part of the SureSTART WebSeal line) is a high-performance sealing mat designed specifically for 96-well microplates with 8 mm square wells. Manufactured from premium, clear silicone, this mat provides a secure, leak-proof seal that prevents sample evaporation and cross-contamination during storage and analysis. A key feature of this specific model is its pre-slit (slotted) design, which allows for effortless penetration by chromatography autosampler needles without coring the material or creating a vacuum within the well. Capable of withstanding extreme temperatures from -80°C to +121°C, the 60180-M123 is an ideal, resealable solution for high-throughput High-Performance Liquid Chromatography (HPLC), Gas Chromatography (GC), and long-term cryogenic sample storage.

Technical Performance and Design

• Pre-Slit Silicone Construction: The slotted plugs ensure easy needle penetration and retraction, preventing the autosampler needle from bending and eliminating the risk of vacuum formation that can alter sample aspiration volumes.

• Superior Resealability: The high-quality silicone elastomer exhibits excellent shape-memory, instantly closing the slit after needle withdrawal to protect the remaining sample from evaporation during multiple injection sequences.

• Broad Temperature Stability: Engineered to perform seamlessly in ultra-low temperature freezers at -80°C and fully dry-heat autoclavable at +121°C, making it suitable for both cold-chain biological storage and high-heat sterilization protocols.

• Chemical Compatibility: The robust silicone matrix provides high resistance against a variety of standard chromatography solvents, ensuring that no extractables or leachables interfere with sensitive downstream analytical results.

Key Benefits & Applications

• Autosampler Optimization: The industry standard for HPLC and GC autosamplers, safely handling volatile organic samples while maintaining the integrity and alignment of fragile injection needles.

• High-Throughput Integration: Perfectly matches the SBS/ANSI footprint of 96-well square plates, enabling smooth integration into automated robotic liquid handling and plate-stacking systems without catching or tearing.

• Cost-Effective Durability: Highly durable and repeatedly resealable, offering a more reliable and reusable alternative to heat-applied foil seals or adhesive tapes that must be discarded after a single pierce.

• Cross-Contamination Prevention: Each of the 96 silicone plugs seats deeply into its corresponding well, creating an isolated micro-environment that prevents well-to-well crosstalk during transport or orbital shaking.
