Rates intro
All users are charged fees for instrument usage, facility services, and training. Rates are reviewed annually and posted here. Contact the Facility Director with questions about rates listed here or any services/consumables not listed. Currently, charges are based on the time logs and not the reservation. However, this policy is subject to change if users repeatedly reserve excess time. Invoice summaries are sent monthly to lab PIs.
It is the responsibility of the user/lab to notify the Facility Director of changes to project MFKs.
