ClearASeal Weld

ClearASeal Weld

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 cycles. 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.
