Abstract:
An apparatus for coating a substrate comprising:(a) a vessel for a solution having a bottom end and an open top end, and defining a vertical axis perpendicular to the bottom end; (b) an insert device having a bottom surface and a top surface and nested within the vessel, wherein the insert device defines a passageway dimensioned for a substrate which is parallel to the vertical axis and extending through the insert device, wherein the passageway is dimensioned to allow a clearance between the passageway and the substrate for coating of the solution on the substrate, and wherein the insert device also defines at least one bypass channel extending through the insert to allow the solution within the vessel to flow through the bypass channel to the top surface of the insert device; and (c) an overflow container positioned adjacent the vessel to catch the solution runoff front the top surface of the insert device.
