Peelable heat sealing film, optically clear; suitable for qPCR and optical applications

Principle

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 Heat Seal is an optically clear laminate film forming a peelable seal to polypropylene, polyethylene, polystyrene, polycarbonate and cyclic olefin copolymer (COC) plates. Samples can also be accessed by pre-piercing with a blade, needle or our Pierce Plate (4ti-0398).

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 Heat Seal forms a complete seal to a plate enabling both low temperature uses, including low temperature storage, and high temperature uses, such as PCR (when used with a pressurised heated lid).

This seal demonstrates moderate solvent resistance and can be utilised for short term compound storage at room temperature.

It is available as sheets, for use with manual and semi-automated sealers, such as our 4s3™ Semi-Automatic Sheet Heat Sealer, and in multiple roll formats compatible with specified automated heat sealers, such as our a4S Automatic Roll Heat Sealer. Our sheet seals are inter-leaved with paper sheets to help denote which side is the sealing side and aid removal of one sheet at a time from the pack.

For applications requiring high tensile strength (e.g. bead mill applications) please see our Clear Heat Seal Plus.
