We usually order stuff like that from Entegris. I didn't see it in a quick perusal of their website at wafercare.com, but I know they have stuff off catalog, so they may be able to help you if you give them a call. Jesse P.S. You didn't specify what diameter of wafers you're using.

I realize most tooling is built for industry standard 25-wafer cassettes, but I am only inquiring about wet chemical baths as processing in smaller containers with smaller cassettes would save us a lot of dollars in chemicals. Thanks in advance.
