Porvair Sciences Ultraseal™ Peel Seal Foil - Sterile Sheet SF04078SS

Ultraseal™ Peel Seal Foil - Sterile Sheet SF04078SS is a sterile foil laminate sheet used to heat-seal microplates for secure, peelable containment. It forms a complete, non-pierceable seal compatible with polypropylene plates and is suitable for low temperature storage down to -80°C and for PCR applications up to 110°C when used with a pressurized heated lid. Primary uses include PCR, very low temperature sample storage, and short-term compound storage.

Key Features:

• Format: Sterile sheet (Sheet)
• Size: 125 mm x 78 mm
• Material: Foil laminate, opaque
• Seal integrity / temperature range: -80°C to 110°C
• Peelable: Yes; Pierceable: No
• Solvent resistance: Moderate
• Recommended sealing: 175°C for 2 seconds

Advantages:

• Provides a complete, heat-sealed barrier for reliable containment during low-temperature storage and PCR.
• Peelable design allows removal from polypropylene plates even after -80°C storage without piercing the plate.
• Sterile sheet format reduces contamination risk for sensitive molecular biology and PCR workflows.
• Moderate solvent resistance enables short-term compound storage at room temperature.
• Opaque foil laminate offers good liquid barrier properties for secure sample protection.
