[Ifeffit] sample holders

I beg the indulgence of the list owner to post a question not directly related to Ifeffit. Where can on purchase sample holders to be used in the SSRL beam (both for liquid samples and solid ones)? I've asked some researchers at SSRL and at UCB but they use ones milled at their respective institutions, and I don't have this option.
