Porvair Sciences Pierce Seal Foil - 115 mm Roll SF06115LR

Pierce Seal Foil - 115 mm Roll SF06115LR is a pierceable, non-peelable heat-sealing foil supplied as a 115 mm wide laboratory roll for sealing microplates and plate-format sample containers. The foil provides a high solvent-resistant, DMSO-resistant laminate suitable for low-temperature and ambient sample storage, PCR applications, compound storage and sample shipping. Heat sealing provides a secure, full-coverage seal which can be pierced manually or by liquid-handling robots and can be resealed by overlaying another seal.

Key Features:

• Width: 115 mm (roll format)
• Length: 500 m roll
• Material: DMSO-resistant foil laminate
• Temperature tolerance: -20°C to 120°C (seal integrity noted to -20°C to 80°C)
• Sealing: Heat seal (recommended 175°C for 2 seconds)
• Compatibility: Polypropylene (PP) and polystyrene (PS) plates
• Peelable: No; Pierceable: Yes

Advantages:

• High solvent and DMSO resistance protects samples stored in organic solvents and DMSO-containing solutions.
• Heat-sealed, full-coverage closure delivers robust seal integrity for storage, PCR shipping and compound libraries.
• Pierceable design allows access by pipette tips or automated liquid-handling systems without fully removing the seal.
• Resealing possible by overlaying additional seals, enabling repeated access while maintaining sample containment.
