The Thermobond II manual heat sealer from Porvair Sciences Ltd. has been
designed to seal polypropylene collection plates, PCR plates, microplates,
and deep well blocks with a specially prepared pierceable film or foil.
Sealing plates prevents sample evaporation and leakage during storage and
The instrumetn applies heat through the surface of the film, creating a fine
melt of the coating to the plate being sealed. No adhesives are used. High
sample integrity is maintained as no heat is transferred to the sample
during sealing. After sealing, the plate seal can be pierced and the liquid
easily pipetted out.
The insutrment incorporates an ergonomically designed reciprocating handle to
minimise repetitive strain injury (RSI) risk while creating a reproducible,
high integrity seal every time. The plane parallel action of the
reciprocating handle ensures even sealing across the plate preventing sample
evaporation or leakage during storage and transportation. A digital timer
and temperature display further enhance the ease of reproducibly sealing
