My shipping address is Keith Williams, UVA Physics, 382 McCormick Road, Charlottesville VA 22904. Sample size... well I can do very small samples if desired. I was planning to use ordinary microscope coverslips cut into ~1x1" squares. 1mL would easily coat that, many times over.

Question is whether you want me to test exposure, or you... I could do simple tests.

Wish I had some blank plates for my rb, it has plate holders for that, let me see what I can come up with....

The big advantage of spin coating is that it is extremely economical in material. Whatever your emulsion costs, I can tell you that some of the resist I use are far more costly. And unused material can actually be recovered... partially at least.

I suppose now would be a good time to mention that I am also looking into adapting an inkjet for paper coating...
