Pierceable heat sealing foil, high solvent resistance, resealable, suitable for PCR / storage / shipping

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

Pierce Heat Seal is compatible with polypropylene and polystyrene plates. This seal demonstrates good solvent resistance and can be used for low temperature and room temperature compound storage in DMSO and organic solvents.

Pierce Heat Seal can be pierced with a pipette tip manually, or by a liquid handling robot. This seal can be resealed by applying another Pierce Seal straight on top of a previously pierced seal.

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

Pierce Heat Seal sheets are also available with a printed grid reference on the non-sealing surface; see the second image in the photo-reel.
