Our normal staff hours are 8:00 a.m. to 5:00 p.m., Monday through Friday. However, it is recognized that research does not always adhere to a normal workweek schedule, therefore trained and experienced users may request use of the instruments outside of the Core’s staffed hours. Three (3) criteria must be satisfied for after-hours access to be granted for use any CCC resource: sufficient training, experience, as well as demonstration of competency. The first time a user requests such an appointment, prior approval must be given.
