Hours of Operation

EMRC staff are available 9:00 am to 5:00 pm, Monday through Friday. To use the facility outside these hours, users must be approved by the Director for off-hour access and must be trained on the center's procedures and equipment. Access to the facilities during non-business hours is by electronic card key. The Director will authorize Security to activate your Rockefeller University ID card for access to those areas of the center for which you are approved, depending on electron microscope needed.


Service is provided on a first-come first-served basis. EMRC places highest priority for scientists from the Rockefeller.
