Hi Claudia,

I am writing to let you know that your chemical has been ok'd to be used 
in our lab.
Let me know how much of this chemical is coming and I trust that you 
know the routine of getting the yellow labels and the bar code better 
than any body else.
The chemical can be spun on either the headway or Laurell spinner coater.
If you are using the small Oven( mahnaz's oven) I like to review the 
procedure of running wafers in there with you.
