Porvair Sciences Ultraseal™ Peel Seal DMSO Foil - 78 mm Roll SF05078LR

Ultraseal™ Peel Seal DMSO Foil is a heat-sealable, peelable foil laminate supplied as a 78 mm roll for automated or manual plate sealing. It provides a DMSO-resistant liquid barrier for low-temperature and ambient compound storage and is intended for use with polypropylene microplates and compatible sealing equipment. The foil supports storage of samples in DMSO and organic solvents and is suitable for applications requiring peelable, non-pierceable seals.

Key Features:

• Format: 500 m x 78 mm roll
• Material: DMSO-resistant foil laminate
• Seal type and parameters: heat seal; recommended 175°C for 2 seconds
• Temperature range (seal integrity): -20°C to 120°C
• Peelable: Yes; Pierceable: No
• Compatibility: Polypropylene (PP) plates; forms excellent seal to cyclic olefin copolymer (COC)

Advantages:

• High solvent resistance enables storage of samples in DMSO and other organic solvents without seal deterioration
• Peelable foil provides easy access to wells while maintaining strong liquid barrier during storage
• Wide temperature integrity supports both low-temperature storage and high-temperature processes such as PCR when used with appropriate equipment
