In support of the BJCIH B120 controls upgrade project, the B120 ABSL3 suite will be closed during the overnight hours starting on September 20th and ending on November 24th. For these next ten weeks, the outage will occur each night starting at 9:00 pm and ending at 6:00 am the next morning. This work schedule was selected to avoid impacting the research schedule or animal care schedule in the B120 suite.
