Hi Ted, Advanced Infrared Pte Lts makes this equipment, but sorry to say that, none of them it used :-) as we makes new ones. The chamber as well as the loading mechanism are customized based on wafer size. In case you are interested to use the equipment for photoresist stripping, the carbon dioxide operation is more complex than just for the drying. Regards Pavel CEO Advanced Infrared Pte Ltd Singapore ______________________________________________________ If anyone knows where one can purchase a used critical point dryer (fully functional and doesn't require any repairs) at a fairly affordable price, please let me know. Thank you. Ted "Theodore Chi"__________________________________ Do you Yahoo!? SBC Yahoo! DSL - Now only $29.95 per month! http://sbc.yahoo.com
