Clear Weld Seal Mark II 1000 seal roll for a4S heat sealer

Optically clear heat sealing film, non-peelable, difficult to pierce; 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 Clear Weld Heat Seal Mark 2 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 Mark 2 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. Clear Weld Heat Seal Mark 2 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 our Pierce Plate (4ti-0398).

It is available as sheets, for use with manual and semi-automated sealers, such as our4s3™ Semi-Automatic Sheet Heat Sealer, and in multiple roll formats compatible with specified automated heat sealers, such as oura4S Automatic Roll Heat Sealer.
