Two Versatile Laboratory Coating Machines Based on Designs by Samuel B. Grimson

Karl Weiss, Frederick T. O'Grady

This paper describes the design and construction of two small coating machines, one for film, and the other for glass. Special features of these machines include the adaptability for use with a variety of coating liquids, the ability to be operated with very small volumes of liquid, and simple means for the accurate control of the layer thickness. The film-coating machine incorporates a new coating head which is especially useful for the application of volatile coating liquids and multilayer coatings. The working principles and performance characteristics are illustrated by typical applications.
