Clear Weld Heat Seal Mark 2

Optically clear heat sealing film, non-peelable, difficult to pierce; 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 Clear Weld Heat Seal Mark 2 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 Clear Weld Heat Seal Mark 2 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
  • Clear Weld Heat Seal Mark 2 demonstrates a good solvent resistance and can be utilized for long term compound storage
  • Samples can be accessed by pre-piercing with a blade, needle or our Pierce Plate (4ti-0398)
  • This seal is available as sheets, for use with manual and semi-automated sealers, such as our IntelliXseal™ SA Semi-Automatic Sheet Heat Sealer
  • Also available in multiple roll formats compatible with specified automated heat sealers, such as our a4S Automatic Roll Heat Sealer
