Save time and money while improving seal integrity with Thermo Scientific™ heat seal films for the ALPS™ Microplate Heat Sealer. Thermal sealing allows microplates to be resealed after sampling and is ideal for storage applications. When heat sealing, the sealing film is first placed in place on the board and there must be a raised edge around each hole. Heat evenly for a few seconds to allow the sealing film to adhere to the raised edges for a complete seal.
