• Chemistry Instrumentation and Electronics Facility (ChIEF) - This core in Chemistry & Biochemistry is available to the entire campus. They can troubleshoot and repair a wide variety of electronic equipment, saving research groups from having to purchase expensive new products. They are also able to work on new electronic designs that can complement research groups' projects.
• The RII Machining & Welding Center offers a variety of specialized services, provided by a staff with a combined total of over 150 years of machining experience.
