Sigma-Aldrich Clearaseal Weld(Tm) Heat Sealable Film

Our ClearASeal Weld^™ is an optically clear, non-peelable and non-pierceable polymer film forming a permanent seal to polypropylene plates suitable for qPCR, optical applications and storage. The optical clarity enables its use for sealing plates required for imaging use, including fluorescent detection methods such as qPCR and colorimetric assays. The film 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 and it 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.
