Overview

• Heat sealing offers a 100% effective method for plate sealing for a complete seal integrity, as well as being quick and cost effective

• Our 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 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

• Clear Weld Heat Seal demonstrates 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)

• This seal is available as sheets, for use with manual and semi-automated sealers, such as our Semi-Automated Sheet Heat Sealer

• Also available in multiple roll formats compatible with specified automated heat sealers, such as our Semi-Automated Sheet Heat Sealer
