Abstract:
1. A method for efficiently preparing a large number of sample coatings comprising the steps of: (a) forming a series of sample receptacles or wells by providing a flexible substrate and an overlying apertured sheet with the apertured sheet in tight sealing engagement with the substrate; (b) applying different samples of material in liquid form into said receptacles; (c) placing said flexible substrates with said sample receptacles thereon in a centrifuge; (d) activating said centrifuge with said receptacle mounted therein to flatten out the sample material in said receptacles, with the centrifugal force acting perpendicular to the bottom of the receptacles; (e) drying said samples while they are within the centrifuge; and (f) removing the apertured plate to leave the samples exposed on said substrate.
