Dunn Lab Equipment
Dunn Lab Equipment
The Harold K. Dunn Orthopaedic Research Laboratory, guided by the Department of Orthopaedics Resource Task Force, recently enacted new policies for equipment usage in the laboratory spaces.
These policies govern required training/permitting, protective measures, user restrictions, access controls, scheduling, costs, and compliance/accountability for major equipment (e.g., dynamic stereoradiography, laboratory radiography, biorobotics, and CNC/lathe machine tools).
