Polystyrene Foil Seal

Heat sealing offers a 100% effective method of plate sealing, for complete seal integrity, as well as being quick and cost effective.
Our Polystyrene Foil Seal produces a stronger seal to Polystyrene plates than our standard Foil Seal. It 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.
Polystyrene Foil Seal can be pierced with a pipette tip manually, by a liquid handling robot, using the 4titude Pierce Plate, 4ti-0398, or it can be removed by peeling. It can be resealed by applying another Polystyrene Foil Seal directly on top of a previously pierced seal.

Polystyrene Fo il 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.
Polystyrene Foil Seal is free from DNase, RNase, human genomic DNA, bacterial cell, eukaryotic cell, dust, endotoxin/pyrogen. It is available from stock, non-sterile, but can be custom sterilised if required, please contact 4titude. The seal is stable from -20°C to 110°C and is suitable for high temperature incubations.
