Heat Sealing Films

Porvair Sciences has a comprehensive range of seals and foils for thermal and adhesive sealing of microplates. In addition, a full range of re-usable cap mats is available for friction sealing of plates.

Foils and seals for the MicroSeal and MiniSeal Plus are supplied as cut sheets, 125mm x 78mm, in packs of 100. For the automated TriSeal system, these come in roll form. Sample rolls are 5m long, whilst production rolls are either 500m or 610m long, enough to seal 5-6,000 plates on average.

All Porvair heat seals have a sealing integrity range of -80ºC to +120ºC, are resistant to DMSO and TFA as well as most other solvents and will seal Polypropylene plates. For Polystyrene plates, please only use Clear Seal.
