Porvair Sciences Ultraseal™ Clear Seal Perf - 78 mm Roll SF11078LR

Ultraseal™ Clear Seal Perf - 78 mm Roll is a clear, perforated heat-sealing film designed to form non-peelable seals for microplates and similar laboratory vessels. The perforations render the film gas permeable while retaining minimal evaporation, making it suitable for short-term incubation, cell culture, insect and seed storage, and applications where optical clarity is required. The product is supplied as a 78 mm wide roll intended for use with heat-sealing equipment including the Ultraseal Pro.

Key Features:

• Roll size: 610 m x 78 mm
• Material: clear perforated film (non-peelable)
• Temperature range: -80°C to 80°C (up to 110°C with pressurised PCR heated lids)
• Compatibility: polypropylene (PP), polystyrene (PS), polyethylene (PE), cyclic olefin copolymer (COC)
• Recommended sealing: 180°C for 2 seconds
• Properties: gas permeable, good optical quality, moderate solvent resistance

Advantages:

• Perforated design provides gas exchange while minimising evaporation, supporting short-term incubation and biological storage.
• Wide seal integrity temperature range enables use from low-temperature storage to PCR applications with pressurised heated lids.
• Clear film with good optical quality allows visual inspection and optical assays without removing the seal.
• Compatible with common plate materials and standard heat-sealing equipment, facilitating integration into laboratory workflows.
