Porvair Sciences Ultraseal™ Peel Seal Foil - Trial Sheets SF04078TS

Ultraseal™ Peel Seal Foil trial sheets are foil laminate heat-seal sheets designed to form a complete, peelable seal for microplates. They provide a liquid barrier and moderate solvent resistance for applications such as PCR, low-temperature storage (including direct removal from -80°C), and short-term compound storage. The sheets are intended for heat sealing to polypropylene plates and deliver seal integrity across a wide temperature range for laboratory sample handling and thermal cycling workflows.

Key Features:

• Format: Trial sheets, 125 mm x 78 mm
• Material: Foil laminate, opaque, peelable and non-pierceable
• Quantity: 5 sheets per pack
• Temperature range / seal integrity: -80°C to 110°C
• Recommended sealing: 175°C for 2 seconds
• Compatibility: Polypropylene (PP) plates
• Solvent resistance: Moderate

Advantages:

• Forms a complete heat seal delivering effective liquid barrier protection for PCR and low-temperature storage
• Peelable design allows removal even after direct -80°C storage
• Moderate solvent resistance supports short-term compound storage at ambient temperatures
• Rapid heat-seal specification (175°C, 2 s) enables quick, repeatable sealing in automated workflows
