Porvair Sciences Ultraseal™ Peel Seal Foil Super SF14078LR

Ultraseal™ Peel Seal Foil Super is a DMSO‑resistant, peelable foil laminate heat‑seal designed to form a complete seal to microplates for very low temperature storage and high temperature uses such as PCR. The seal is compatible with all plate types, can be removed by peeling even after removal from -80°C storage, and is suitable for short‑term compound storage at room temperature.

Key Features:

• Material: Foil (laminate)
• Format: Roll (78 mm width)
• Peelable: Yes
• Pierceable: No
• Solvent resistance: High (DMSO‑resistant)
• Seal integrity / operating range: -20 °C to 80 °C (lower temp use to -80 °C shown for storage)
• Seal type: Heat seal

Advantages:

• Provides a complete, 100% effective heat seal for secure sample protection during storage and PCR workflows.
• High solvent resistance (including DMSO) enables short‑term compound storage and handling of solvent‑containing samples.
• Peelable after ultra‑low temperature storage (removable even after -80 °C), allowing convenient access to sealed wells without damaging plate contents.
