The scrubbed exhaust maintenance activities in the cleanroom have been successfully completed, and the scrubbed exhaust is now operational. The general exhaust, however, is still not functional. This affects solvent hoods, vacuum systems, and the hydrogen generator. A follow-up e-mail will alert you when the remaining systems are operational. We are anticipating that this will be approximately noon Friday. The laboratories will be closing Thursday morning at 8:00 AM. Please note that the individual equipment will be coming up after the cleanroom startup. Certain tools, such as the evaporators, may take a significant amount of time to bring back into function. Please check Coral for equipment status. John Weaver John R. Weaver Facility Manager Birck Nanotechnology Center Purdue University (765) 494-5494 jrweaver@purdue.edu
