Porvair Sciences Ultraseal™ Peel Seal Foil - Lab Sheet SF04078LS

Ultraseal™ Peel Seal Foil Lab Sheet SF04078LS is a heat-sealable laboratory foil sheet designed to provide a peelable, non‑pierceable liquid barrier for assay plates and low-temperature storage. The product is supplied in lab sheet format (part code SF04078LS) and is intended for sealing polypropylene plates for applications including very low temperature storage and PCR when used with a pressurized heated lid. The foil provides moderate solvent resistance and enables short-term compound storage and reliable seal integrity across a wide temperature range.

Key Features:

• Part code: SF04078LS; format: Lab sheet
• Peelable and non-pierceable foil laminate
• Temperature resistance / seal integrity: -80°C to 110°C
• Recommended heat-sealing: 175°C for 2 seconds
• Compatibility: polypropylene (PP) plates
• Moderate solvent resistance; suitable for short-term compound storage

Advantages:

• Provides a complete heat seal that enables very low temperature storage and high-temperature uses such as PCR (with a pressurized heated lid)
• Peelable design allows plate access without piercing, including after -80°C storage
• Moderate solvent resistance supports short-term compound containment at ambient temperatures
• Simple heat-seal application delivers consistent seal integrity across the specified temperature range
