Porvair Sciences Ultraseal™ Peel Seal DMSO Foil - Lab Sheet SF05078LS

Ultraseal™ Peel Seal DMSO Foil - Lab Sheet is a DMSO‑resistant foil laminate heat seal designed for low temperature and ambient compound storage. It provides a good liquid barrier with high solvent resistance (including DMSO and organic solvents) and is intended to form reliable seals to polypropylene and cyclic olefin copolymer (COC) plates. The product is supplied as peelable, non‑pierceable sheets for laboratory plate sealing and short‑ to medium‑term storage applications.

Key Features:

• Format: Lab sheet, 125 mm × 78 mm
• Quantity: 100 sheets per pack
• Material: DMSO‑resistant foil laminate
• Peelable: Yes; Pierceable: No
• Temperature range / seal integrity: -20°C to 120°C
• Recommended heat sealing: 175°C for 2 seconds
• Compatibility: Polypropylene (PP) and forms excellent seal to COC plates

Advantages:

• High solvent resistance enables storage of compounds in DMSO and organic solvents without seal deterioration
• Good liquid barrier and heat‑seal performance provide reliable containment for low and ambient temperature storage
• Peelable, non‑pierceable construction prevents accidental penetration while allowing controlled access when needed
• Simple heat sealing with short cycle (175°C, 2 s) for fast, reproducible sealing of microplates
