Porvair Sciences Announces New Range of Aluminium Heat Seals for PCR, Storage & Life Sciences Applications

The new foils are precision engineered to an exact thickness and come colour-coded to enable easy identification of the different types. In addition, the pre-cut foil sheets are marked to ensure that they are always used the right way up, thus minimising possible damage to the sealing head of a thermal heat sealer which can occur when a foil is inserted the wrong way up.

Four different foils have been released: 229480 is a 20 micron foil, colour coded green, designed for very easy piercing by robotic liquid handling or pipette tips ; 229471 is a re-sealable 38 micron foil, colour coded blue, that is easily pierced as well as peelable ; 229470 is a 70 micron non-piercable foil, colour coded red, that offers good tear strength and has an easily pealed polyester backing ; 229482 is a 85 micron foil, colour coded black, for heavy duty use including storage and transport applications.

The new Porvair aluminium foils offer significant ease of use and application benefits when compared to traditional thermal foils and may be used with most commercially available heat sealers.
