An Update on the Plant Sciences Stable Isotope Facility

Dear Faculty, Staff, Students, and Supporters,
After a lengthy review process and careful consideration, we have made the difficult decision to sunset the Stable Isotope Facility (SIF) in its current form, effective July 26, 2026.

The Department of Plant Sciences continues to face hard decisions surrounding funding allocation given the campus-wide request to reduce budgets. Over the past several years SIF has been operating with a significant and growing deficit and, despite extensive efforts over the last several months to find a solution that would allow the facility to continue to provide services to the research community, we have not found a model that is financially sustainable.

I want to thank SIF’s staff for their excellent work and dedication these past 25 years, and everyone who has played a role in supporting this facility.

We are committed to doing our best to support the researchers who rely on the facility during this transition, and will be in touch with individual clients about details of specific plans for handling existing orders over the next several weeks.

Sincerely,
Daniel Potter
Professor and Chair, Department of Plant Sciences
University of California, Davis

SIF Guest Balance Calendar

The SIF has a natural abundance balance available for a limited number of guest users. An appointment is required. Safety training is required prior to guest access to the balance. Please remember to wear appropriate PPE, including closed-toed & closed-heeled shoes and full length pants. The SIF staff have the right to request that you leave the lab if you are not wearing appropriate lab attire.

This calendar reflects the approximate availability of the balance; "busy" means the balance is not available. The SIF has the right to cancel appointments in the event the SIF needs to use this equipment. This balance is for natural abundance samples only. Please contact us to discuss you samples if there is any enrichment/tracer.
