Recharge Rates & Schedule

The philosophy of the Core is to provide access to necessary instrumentation in a highly efficient and economical fashion. The Core sustains equipment maintenance through recharges. Consolidating equipment use amongst a wide variety of investigators ensures optimal equipment use, thereby providing economy in equipment maintenance. Recharge rates for the use of metabolic chambers (CLAMS), EchoMRI, DEXA and Seahorse analyzers are based upon maintenance and service contract costs. The recharge rates are approved by the UCSF Recharge Office.

All UCSF and affiliated laboratories pay the same rates as listed below. As UCSF subsidizes facilities maintenance, external academic researchers must pay an additional 26% overhead charge. Some instruments, pending available use patterns, may also be used by external, commercial researchers at rates contracted through the UCSF Technology Transfer Office. Please contact this Core for Inquiries.

Flux Pak






  • CLAMS consists of 16 metabolic chambers.
  • CLAMS is always run by core staff, and users can be trained on other equipment or can now place a request for core staff to run the instrument on their behalf.


  • FIMS consists of two systems of 24 chambers.
  • We no longer charge per block of up to 12 chambers and up to one week. We now charge per chamber and per day.

DEXA Piximus

  • The anesthesia kit is provided at no charge by LARC floor supervisor, although it has to be reserved in advance on 6th floor PSB (reservation sheet).
  • DEXA Piximus, EchoMRI and Blood Pressure Analysis System: We charge actual time, please log start and end time on the respective time sheet coming with the equipment (clipboard).

Seahorse Bioscience XFe24 Extracellular Flux Analyzer

Labs can buy their own FluxPaks through Agilent, but we do offer individual extracellular flux assay kit or FluxPak (the Sensor Cartridge, a Utility Plate to hydrate the sensor and a Standard V7 Cell Culture Microplate), V28 Cell Culture Microplate (for tissue), and Islet Capture Microplate for a fee. Calibrant is available free of charge on the shelf behind the analyzer.
