Eppendorf Storage Foil Adhesive Microplate Seal Pack of 100 Seals

Eppendorf Storage Foil Self-Adhesive Microplate Seals, Aluminum, Non-Sterile (0030127889) – Pack of 100

The Eppendorf Storage Foil Adhesive Seals (0030127889) are high-integrity, pierceable microplate closures engineered to safeguard temperature-sensitive, light-sensitive, and volatile samples in high-throughput screening, compound storage, and analytical workflows. Precision-manufactured from soft, conformable aluminum foil coated with a specialized cold-resistant acrylic adhesive, these seals create a tight, leak-proof barrier across individual microplate wells, preventing sample evaporation, cross-contamination, and solvent loss. Designed for complete light shielding, the opaque aluminum layer protects light-sensitive fluorophores, light-reactive compounds, and Luminescence assay substrates. Pierced easily with standard pipette tips or robotic liquid handling probes without tearing off adjacent well seals, this pack of 100 non-sterile foil seals provides high-performance sample protection for PCR, biobanking, and long-term deep-freeze storage.

Technical Performance & Structural Attributes

• Complete Light Shielding: Solid aluminum foil layer forms an impermeable barrier against ambient light exposure, preserving light-sensitive compounds and fluorescent tags.
• Pierceable Aluminum Membrane: Easily penetrable with manual micropipette tips, robotic needles, or automated liquid handling probes without causing jagged tears or leaving sticky residues on tips.
• Wide Thermal Stability Range: Specialized cold-resistant acrylic adhesive remains pliable and sealed across extreme temperatures, from cryogenic freezers (-80°C) up to thermal cycling conditions (+120°C).
• Low Evaporation & Solvent Resistance: Prevents liquid loss and concentration changes in volatile organic solvents such as DMSO, ethanol, and aqueous assay buffers.
• End Tabs for Easy Application: Features perforated double end tabs for simple, aligned positioning over 96-well or 384-well microplates without touching the active adhesive area.
