Porvair Sciences Ultraseal™ Peel Seal DMSO Foil - Sterile Sheets SF05078SS

Ultraseal™ Peel Seal DMSO Foil – Sterile Sheets (SF05078SS) is a sterile, DMSO‑resistant foil heat‑seal sheet designed to provide an effective liquid barrier for compound and sample plates. The product delivers a peelable, non‑pierceable seal to polypropylene and forms an excellent seal to cyclic olefin copolymer (COC) plates while producing a weld (non‑peelable) seal to polyethylene. It is intended for low‑temperature and ambient compound storage in DMSO and organic solvents, and for secure sample protection during storage and transport.

Key Features:

• Format: Sterile sheets (sheet format)
• Material: DMSO‑resistant foil laminate
• Size: 125 mm × 78 mm
• Peelable: Yes (peelable from PP and COC); Pierceable: No
• Temperature range / seal integrity: -20°C to 120°C; recommended sealing 175°C for 2 seconds
• Solvent resistance: High — compatible with 100% DMSO storage (manufacturer tested)

Advantages:

• High solvent resistance enables safe low‑temperature and room‑temperature storage of compounds in DMSO and many organic solvents
• Provides a reliable liquid barrier and full heat‑seal integrity for secure plate storage and transport
• Peelable access from polypropylene/COC plates while forming an irreversible weld seal to polyethylene where required
