Porvair Sciences Ultraseal™ Clear Seal Pierce - 78 mm Sterile Roll SF03078SR

Ultraseal Clear Seal Pierce is a heat-sealing laboratory film supplied as a 78 mm sterile roll (SF03078SR) designed to form complete seals to microplates and labware. The clear, optically transparent polyester/polymer film is pierceable (non-peelable) and is intended for PCR/qPCR, optical assays and automated sampling workflows where needle or capillary puncture access is required. The seal provides temperature resilience for moderate low- and high-temperature applications and is suitable for short-term sample storage and plate-based workflows.

Key Features:

• Format: 78 mm sterile roll (SF03078SR)
• Seal type: Thin clear polyester/polymer heat-sealing film; non-peelable, pierceable
• Temperature range: -80°C to 110°C (110°C when used with pressurised PCR heated lids)
• Recommended sealing: 175°C for 2 seconds
• Compatibility: Polypropylene (PP), Polyethylene (PE), Polystyrene (PS), Cyclic Olefin Copolymer (COC)
• Optical clarity suitable for imaging and fluorescence-based assays

Advantages:

• High optical clarity enables imaging and fluorescence/qPCR detection without compromising assay readout
• Pierceable, non-peelable construction supports automation and direct access by autosampler needles, capillaries and pipette tips
• Heat-seal integrity reduces evaporation and provides a complete seal across a wide temperature range for reliable short-term incubation and storage
