IST-103 ClearASeal PierceTM Heat Sealing Film

From £6.00

Clear pierceable film ideal for use with ABI 3730 sequencer



Thin polyester heat sealing film which is easily pierceable with autosampler needles/ABI® 3730. The seal is suitable for PCR, qPCR and optical applications.

  • 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 Pierce heat sealing film is an optically clear polyester backed film, forming a pierceable seal to polypropylene, polyethylene, polystyrene and cyclic olefin copolymer (COC) 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
  • Its pierceability renders it useful for automation and for use on needle, capillary and tip based liquid handling systems
  • It is effective on the ABI®3730 capillary sequencer, removing the need for the use of expensive septa mats
  • The ClearASeal Pierce forms a complete seal to a plate enabling moderately low and high temperature uses, including PCR when using a pressurized heated lid thermal cycler
  • It demonstrates a moderate solvent resistance and can be utilized for short 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
