Updated 03/29/24: Starting Monday April 1st at 8AM, the CNF will resume 24/7 hour operations. The CNF would like to extend our gratitude to the College of Engineering facilities team for their efforts in finding the long-term solution to get the CNF back to 24/7 operation. Your patience and understanding during the recent reduced hours of operation are greatly appreciated.

Updated 03/25/24: This Saturday March 30th the CNF cleanroom, packaging lab and 2nd floor labs will be closed to users due to a campus wide access control software upgrade that will prevent the CNF from opening and operating safely

Updated 02/28/24: The CNF will continue to operate with extended hours from 8:00 AM to 10:00 pm Monday through Friday and from 9:00 am to 5:00 pm on Saturday. We are actively pursuing a solution to reinstate 24/7 operations and will keep you updated with any new information as it becomes available.

Update 01/25/24: Extended operating hours will continue from 8AM to 10PM, Monday - Friday, and 8AM - 4PM on Saturdays through February. These CNF working hours may continue beyond the end of February as the College of Engineering facilities team continues working on the solution to restore 24/7 operation at CNF.

Update 12/18/23: CNF will close for Winter Break beginning 12 noon Friday December 22, 2023 and will reopen on Thursday, January 4th at 12:00 noon. When we reopen, we will be switching from CORAL to the new lab management software, NEMO.

Update 11/28/23: Please check our LAB Hours webpage at https://cornellcnf.link/hours for the most current information on CNF Cleanroom hours. 


CNF prides itself on providing a world-class, open user facility with flexible policies to meet the needs of our broad community. To comply with New York State’s updated building codes that impact Cornell’s Duffield Hall, the home of CNF’s cleanroom and select 3rd floor research labs, the CNF cleanroom will operate with a reduced evening and weekends schedule for a limited time.

Starting Tuesday, October 10th, the following schedule will be in place:

• Cleanroom access limited - see the Lab Hours webpage for current hours.
• CNF 2nd floor labs, Phillips Hall packaging lab, and the CAD room are open 24/7 with no change.

We understand that this limits the availability of CNF resources for some of our users, and we apologize for the short notice. Cornell is working diligently on a long-term solution so that CNF can return to 24/7 operation as soon as possible.
