Product Information

Suitable for compound storage and PCR, peelable, pierceable

Our Foil Seal is compatible with polypropylene and polystyrene plates. This seal demonstrates moderate solvent resistance and can be used for low temperature compound storage in DMSO and organic solvents and short term room temperature storage.

The Foil Seal can be pierced with a pipette tip, manually or by liquid handling robots, or it can be removed by peeling. It can be resealed by applying another Foil Seal directly on top of a previously pierced seal.

Our Foil 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. A red stripe on the sheet foils clearly indicates the non-sealing surface, for ease of seal orientation and handling.
