Heat sealing offers a 100% effective method for plate sealing for a complete seal integrity, as well as being quick and cost effective. Clear weld heat seal 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 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 pressurised 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. It demonstrates a good solvent resistance and can be utilised for long term compound storage. Samples can be accessed by pre-piercing with a blade, needle or a pierce plate.
