Porvair Sciences Ultraseal™ Clear Seal Pierce - 78 mm Roll SF03078LR

Ultraseal™ Clear Seal Pierce is a thin, heat-sealing polyester film supplied as a 78 mm roll (part code SF03078LR) designed to form complete, non-peelable seals that are pierceable by autosampler needles and capillaries. The seal provides good optical clarity for imaging and fluorescent detection methods such as qPCR, and is suitable for PCR and other thermal applications when used with a pressurised heated lid. The pierceability makes it suitable for automated workflows, including use with ABI 3730 sequencers.

Key Features:

• Roll width: 78 mm; Product code: SF03078LR
• Material: thin polyester heat-sealing film
• Seal type: Heat seal, non-peelable but pierceable
• Temperature range: -80°C to 110°C (110°C with pressurised heated lids); recommended sealing 175°C for 2 seconds
• Compatibility: COC, PE, PP, PS; suitable for ABI 3730 sequencer and automated needle/capillary systems
• Optical clarity: Good (suitable for fluorescent and colorimetric assays)
• Solvent resistance: Moderate

Advantages:

• Pierceable, non-peelable construction enables secure seals while permitting automated needle/capillary access for sampling and sequencing
• Good optical clarity supports imaging and fluorescent detection in qPCR and other optical assays
• Wide thermal tolerance allows use in PCR and low-temperature storage when used with appropriate heated lids
• Heat-sealing provides complete seal integrity for reliable short-term compound storage and automated processing
