3mm slits across the film allow gas exchange, optically clear, suitable for imaging, peelable

Heat sealing is a quick and cost effective method of plate sealing. Our Gas Permeable Clear Seal is based on our Clear Seal, with the addition of 3mm slits across the width of the seal. These slits render the seal gas permeable, whilst retaining evaporation to a minimum, compared to the use of lids.

The Gas Permeable Clear Seal is compatible with polypropylene, polyethylene, polystyrene and cyclic olefin copolymer (COC) plates. The seal can be removed by peeling, or it can be pierced with a pipette tip manually, using a liquid handling robot or with our Pierce Plate (4ti-0398).

The Gas Permeable Clear Seal has a wider seal integrity temperature range, from -80°C to 110°C, than our Gas Permeable Seal Mk 2. It can be used for insect and seed storage, as it enables gas exchange, whilst providing an inert surface with no adhesive to interfere with the well contents.

The Gas Permeable Clear Seal is available as sheets, for use with manual and semi-automated sealers, such as our 4s3™ Sheet Heat Sealer, and in multiple roll formats compatible with specified automated heat sealers, such as our a4S Roll Heat Sealer.
