The sealing foil is made of aluminium. The foil can be used for a safe sealing of single tubes for singular sample application. The foil makes it possible to store the tubes with a temperature down to -80°C. The tubes can be re-stored again, if the use of the foil is no longer necessary, with screw caps or push caps. You’ll need a Heat Sealer to use this kind of sealing.
