Porvair Sciences Ultraseal™ Clear Seal Perf - 115 mm Roll SF11115LR

Ultraseal™ Clear Seal Perf is a clear, perforated heat-sealing film designed to provide gas-permeable sealing for microplates and laboratory plate-based workflows. It preserves optical clarity for imaging and optical assays while allowing gas exchange for short-term incubations, agriculture/seed storage, insect storage and cell culture applications. Supplied as a 115 mm roll, part code SF11115LR, the seal is intended for use with heat-sealing equipment to deliver consistent, complete seals across plate formats.

Key Features:

• Format: 115 mm roll; Part code SF11115LR
• Material/Finish: Clear perforated film with good optical quality
• Perforation/Gas exchange: Perforated (3 mm slits) to render the seal gas permeable
• Seal type and conditions: Heat seal; recommended sealing 180°C for 2 seconds
• Temperature range: -80°C to 110°C (usable with pressurised PCR heated lids)
• Compatibility: Polypropylene (PP), Polystyrene (PS), Polyethylene (PE), Cyclic Olefin Copolymer (COC)
• Peelability/Pierceability: Non-peelable; pierceable

Advantages:

• Maintains optical clarity suitable for imaging and qPCR/optical assays
• Perforated construction enables gas exchange while minimising evaporation during short-term incubations
• Provides a consistent, complete heat seal for reliable containment and handling across compatible plate materials
• Wide operational temperature range supports both low-temperature storage and high-temperature thermal cycling when used with pressurised lids
