SDSS Sample Preparation Laboratory
We are excited to announce that phase 2 of the Sample Preparation Laboratory (SPL) renovation is currently underway. During phase 2, the SPL will be closed to new users. Lab A55 mineral separation is still available to existing trained users only. The new and renovated SPL will open again in February 2026. We are currently not training new users or approving access to any of the SPL areas impacted by the refresh. Please reach out to Dale Burns (dhburns@stanford.edu) for updates and/or more information.
The Sample Preparation Laboratory (SPL) is a shared, open-access laboratory that provides centralized sample preparation techniques, instruments, technical expertise, and training that anyone at Stanford can use. SPL is equipped for various sample preparation methods, including sample crushing, grinding, and pulverization, as well as sample cutting, coring, and drilling, and mineral separation for a wide range of sample types, such as rocks, minerals, soils, and plant tissues. The most common sample preparation workflows in SPL are:
- Powdering samples for geochemical or isotopic analysis.
- Cutting/drilling/coring rocks for geophysical analysis or generating thin section billets.
- Mineral separation.
- Resin mounting and sample polishing
- Sample imaging
These work flows can be manipulated to accommodate other sample preparation needs. Reach out to the Laboratory Manager to learn more. Facilities are free to use and open to all Stanford affiliated students, staff, faculty, and visitors. The SDSS Sample Preparation Laboratory is very concerned with safe uses of machinery & chemicals and avoiding sample cross contamination.
The Sample Prep Lab is a collection of rooms in the sub-basement of the Mitchell Earth Sciences Building. Please navigate to the Equipment tab to learn more about what is available. For access to these lab rooms, read the training instructions under the Access and Training and Safety tabs or reach out to the Laboratory Manager.
