Porvair Sciences launched a new online service (www.microplateseals.co.uk) providing organizations with access to next day delivery on competitively priced, high performance microplate thermal seals. Available in a wide choice of color-coded designs, Porvair microplate thermal seals are available optimized for use with all brands of assay plates. These easy to use thermal seals work with all commercially available heat sealers that take pre-cut strip seals. They are printed in five different colors and marked “This way up” to ensure easy selection of the right gauge of seal and correct positioning on the microplate. Seals are compatible with most heat sealers. Each aluminum foil microplate seal is spray-coated with an acrylic varnish that is solvent resistant and will not contaminate your samples. It also makes a permanent weld seal to polystyrene and polypropylene microplates. The peelable foil is actually a laminate of aluminium and polyester that provides durability and strength, while remaining easy to remove. A sample pack of foils is available on request from Porvair Sciences. Porvair color-coded optically clear seals are available in two gauges, both printed black “This way up” for ease of use. The thinner gauge gives the best optical results and is easily removed. The thicker material, while remaining clear after heat sealing, is optimized for long-term cold storage applications down to -20 °C.
