There should be a new bottlen in the cleanroom! I just brought it in a  
week ago.

Users are reminded to ensure the ZEP520a material needs to be replaced  
to the refrigerator after dispensing onto your wafers or the material  
will hydrolyse and gel.

Did anyone use it or see it in the fab yesterday?
