Storage Mats have been designed to fit our polypropylene plates and have the added advantage of being able to seal our 96 well, corner notch polystyrene plates as well. Made from special co-polymer that offers a high vapour barrier, Storeage Mats effectively seal each well and limit moisture exchange at temperatures ranging from -70ºC to 40ºC. The Storage Mats also have a unique design that minimises the depth of penetration in each well, allowing at least 200 µl of sample volume per well in a sealed plate. Packaging: 25/pk 100/cs
