Abstract:
1. A method of forming seals around a plurality of wells of a microtitre reaction plate, the wells being defined by a plurality of apertures in a planar surface of the reaction plate through which each well receives a reagent or sample that is subject to one or more reactions while confined and sealed within the reaction plate, each well having a volume of 200 microliters or less, the method comprising the step of attaching a plastics film to the planar surface of the reaction plate by forming seals around the apertures in the planar surface of the reaction plate for sealing the reagent or sample with the wells, using near-infrared diode laser welding to form each well seal, the plate being less than 4 mm thick and having at least 1152 wells per plate.
