WebJan 7, 2002 · Note to customers regarding uniformity tolerance 01/04/10 . Question: Does Laurell quote a uniformity tolerance for its spin processors? Answer: We do not quote a uniformity tolerance for our Spin Coaters. We have many customers, in academia and industry, who are spin coating many different materials using our spin processors. WebSpin coating is a transient process of flow and mass transfer. Coating thickness and uniformity depend on the competition between centrifugally driven drainage of the liquid film and concentration-driven evaporation of solvents. sushi in asheboro nc
