ClearASeal WeldTM Heat Sealing Film

Optically clear heat sealing film which is non-peelable and non-pierceable. The seal is suitable for qPCR, optical applications and storage.

  • Heat sealing offers a 100% effective method for plate sealing for a complete seal integrity, as well as being quick and cost effective
  • Our ClearASeal Weld is an optically clear polymer film forming a permanent seal to polypropylene plates
  • The optical clarity of this seal enables its use for sealing plates required for imaging use, including fluorescent detection methods such as qPCR and colorimetric assays
  • The ClearASeal Weld forms a complete seal to a plate, enabling both low and very high temperature uses, including low temperature storage and high temperature incubations
  • This seal is suitable for PCR/qPCR, even without the use of a pressurized heated lid, and is 100% effective when used in water bath thermal cyclers
  • The permanent nature of this 100% effective seal renders it suitable for the storage and disposal of hazardous material
  • ClearASeal Weld demonstrates a good solvent resistance and can be utilized for long term compound storage
  • This seal is available as sheets, for use with manual and semi-automated sealers, such as our HeatASeal 500 Sealing Machine
  • Also available in multiple roll formats compatible with specified automated heat sealers, such as our Wasp or Chameleon XT
