Clear Weld Heat Seal manufactured by Azenta Life Sciences is an optically clear polymer seal which can form a permanent seal to polypropylene plates, enabling both low and very high temperature uses, including low temperature storage and high temperature incubations. The permanent nature of this 100% effective seal renders it suitable for the storage and disposal of hazardous material. This seal is also 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 optical clarity of this seal makes it ideal for sealing plates used for imaging use, including fluorescent detection methods such as qPCR and colorimetric assays. Clear Weld Heat Seal features 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).
