Porvair Sciences Ultraseal™ Clear Seal Perf - 78 mm Sterile Roll SF11078SR

Ultraseal Clear Seal Perf is a clear, perforated heat-sealing film supplied as a sterile 78 mm roll for sealing microplates and similar labware. The product provides a gas-permeable, non-peelable barrier that maintains optical clarity and moderate solvent resistance for short-term incubations, cell culture, insect and seed storage applications. The roll format is compatible with the Ultraseal Pro sealer and is intended for heat-seal plate sealing workflows.

Key Features:

• Format: sterile roll, 78 mm width, 610 m length
• Seal type: heat seal, non-peelable, pierceable
• Material properties: clear perforated film, good optical quality, moderate solvent resistance
• Gas permeability: perforated (3 mm slits across width) to allow gas exchange
• Temperature range / seal conditions: seal integrity -80°C to 110°C; recommended sealing 180°C for 2 seconds
• Compatibility: polypropylene (PP), polystyrene (PS), polyethylene (PE) and cyclic olefin copolymer (COC)
• Compatible equipment: Ultraseal Pro

Advantages:

• Provides gas permeability via perforations to enable gas exchange during short-term incubations while limiting evaporation compared to using lids
• Clear, optically suitable film supports applications requiring visual or optical access to wells
• Sterile roll format and heat-seal application deliver consistent, complete seal integrity for plate-based workflows
