The Samuel Roberts Noble Microscopy Laboratory, the core imaging facility of the University of Oklahoma, is a central shared use facility offering access to instrumentation, training, and service using advanced light microscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM).

Our mission is to provide effective and efficient access to core imaging and analytical characterization technologies. We welcome all OU-Norman, OUHSC, and OMRF student, faculty, and staff researchers at our centralized location the OU-Norman main campus. Clients from other universities, foundations and industry are welcome to use this equipment as well, and such work may be done on an invoice or contract basis.

In addition to instrument access, SRNML personnel offer advice, hands-on training, education, and research collaboration. The SRNML aims to promote, enable, and encourage cutting-edge education and research using the core’s instrumentation.

We have a range of sample preparation equipment available; our staff work with users and provide training. Please see our equipment and getting started pages for more information, and don’t hesitate to contact us.

Starting July 1st, 2022 - transition to iLab

Starting July 1st, all researchers internal and external to OU must register and access lab resources through our new iLab portal.

Researchers with existing iLab accounts through other facilities should be able to login to our core facility's iLab page with your current account.

Starting July 1st, the Samuel Roberts Noble Microscopy Lab at University of Oklahoma is excited to start using an online system to streamline the process of ordering and billing for core service requests. All facility users are invited to use the system, which requires a one-time registration as discussed below.  Once you are registered, the system will enable you to place service requests, provide required approvals, and monitor progress.

Researchers with existing iLab accounts through other facilities should be able to login to our core facility's iLab page with your current account.
