Porvair Sciences Ultraseal™ Clear Seal Weld - 115 mm Trial Roll SF02115TR

Ultraseal™ Clear Seal Weld is an optically clear heat-sealing film supplied as a 5 m trial roll (115 mm width) that forms a permanent, non-peelable, non-pierceable seal to polypropylene plates. The film provides strong bonding for thermal cyclers and is suitable for PCR and qPCR workflows, optical imaging including fluorescence qPCR, long‑term storage and secure containment of hazardous materials. Recommended sealing conditions are 175°C for 2 seconds and the seal remains effective across a wide temperature range from -80°C to 110°C.

Key Features:

• Size: 5 m × 115 mm (trial roll)
• Material: Polymer heat-sealing film
• Transparency: Clear; suitable for optical and fluorescence detection
• Seal type: Permanent heat seal; non-peelable and non-pierceable
• Temperature range: -80°C to 110°C; recommended sealing 175°C for 2 seconds
