Full description

Suitable for polystyrene assay microplates, peelable

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.
