The clear weld heat seal is an optically clear polymer film forms a permanent complete seal to polypropylene plates, enabling both low and very high temperature uses, including low temperature storage and high temperature incubations.

• Permanent seal, difficult to pierce, non-peelable
• DMSO and solvent resistant
• Suitable for PCR/qPCR, even without the use of a pressurized heated lid, and is 100% effective when used in water bath thermal cyclers
• 100% effective seal, suitable for the storage and disposal of hazardous material
• Good solvent resistance and can be utilized for long term compound storage
• Autoclavable (121 °C): once autoclaved, not recommended for PCR applications
• Temperature range: –80 to +110 °C
• Non sterile

Optical clarity enables use for sealing plates required for imaging use, including fluorescent detection methods such as qPCR and colorimetric assays.

Heat sealing offers a 100% effective method for plate sealing for a complete seal integrity, as well as being quick and cost effective. These clear heat seals form a complete seal to a plate enabling both low temperature uses, including low temperature storage, and high temperature uses, such as PCR.

The sheet seals fit all standard SBS footprint PCR and qPCR plates, microplates, assay and storage plates, from 12 to 1536 wells.
