Porvair Sciences has announced a range of aluminium heat seals for PCR, storage and life-science applications.
The foils are precision engineered to an exact thickness and come colour-coded to enable easy identification of the different types.
The pre-cut foil sheets are marked to ensure that they are always used the right way up, minimising the damage to the sealing head of a thermal heat sealer that can occur when a foil is inserted the wrong way up.
229480 is a 20um foil that is colour coded green and designed for easy piercing by robotic liquid handling or pipette tips.
229471 is a resealable 38um foil that is colour coded blue and is is easily pierced, as well as peelable.
229470 is a 70um non-piercable foil that is colour coded red, offers good tear strength and has an easily pealed polyester backing.
229482 is a 85um foil that is colour coded black and is suitable for heavy duty use in applications such as storage and transport.
The Porvair aluminium foils are said to offer significant ease of use and application benefits when compared to traditional thermal foils, and may be used with most commercially available heat sealers.
