Porvair Sciences Ultraseal™ Pierce Seal Foil PS - 78 mm Sterile Lab Roll SF07078SR

Ultraseal™ Pierce Seal Foil is a sterile, heat-sealable foil roll designed to provide a pierceable closure for microplates and other laboratory vessels. The foil can be pierced manually or by liquid‑handling robots and can be resealed by applying another foil seal over a previously pierced area. It is intended for low‑temperature storage and PCR applications where a secure, solvent‑resistant, pierceable barrier is required.

Key Features:

• Format: Lab roll, 78 mm width, sterile
• Material: Foil (pierceable)
• Pierceable manually or by liquid‑handling robots
• Resealable by applying another Pierce Seal Foil over a pierced seal
• Seal integrity / temperature range: -20 °C to 80 °C

Advantages:

• Enables pipetting access without full removal of the seal, supporting manual or automated workflows
• Allows resealing after piercing to maintain containment and reduce evaporation
• High solvent resistance and heat‑seal format suitable for PCR and low‑temperature storage
• Green dotted line indicates non‑sealing surface for easy orientation and handling
