A flexible, transparent, microwaveable PVDC sealing film offering excellent barrier characteristics against oxygen, moisture and chemical attack. Particularly suited to gel drying applications where it can be used to prevent contamination of the silicone sealing mat of the gel dryer, and to enhance even drying across the gel. It has less tendency to cling than traditional sealing films and therefore does not lift the gel on removal. Can be used to cover and store pre-cast gels for long periods at +40˚C and is UV transparent, allowing use as a cover for agarose gels during observation and photography on a transilluminator.
