Porvair Sciences Ultraseal™ Pierce Seal Foil - 115 mm Sterile Roll SF06115SR

Ultraseal™ Pierce Seal Foil is a sterile, pierceable heat-sealing foil supplied as a 115 mm roll (part code SF06115SR) for laboratory plate sealing and sample containment. It provides a solvent-resistant, non-peelable barrier that can be pierced manually or by liquid‑handling robots and can be re-sealed by overlaying additional seals. Typical use cases include PCR shipping, low‑temperature and ambient compound storage, and secure sample sealing where sterility and solvent resistance are required.
