Teaching: The facility provides teaching for various disciplines within the college of Medicine and other colleges

Research: The facility provides assistance with research projects for the College of Medicine & Health Sciences, other colleges within SQU as well as for governmental and private research centers within the country.

Diagnostic: EMCF provides diagnostic services for SQUH, Ministry of Health Hospital and Private sector Hospitals/Clinics. Diagnostic Screening carried by the Department Pathologist with the assistance of Senior EM Staff.

Training: The facility provides training for SQU Undergraduate and Postgraduate students, Technologists from other institutions and training programs for TEM and SEM available.

Consultancy: Consultancy services for SQU investigators and scientists from other institution within the country.

Electron Microscopy Core Facility (EMCF) at College of Medicine & health Sciences is a multi-user facility and it is imperative that all users work responsibly in the lab.

Access: The Electron Microscopy Core Facility is open Saturday through Wednesday from 8:00 am to 4:00 pm. Arrangements can be made for holidays and after working hours to meet investigator’s needs, by contacting Mr. Issa Al-Amri. Most of the major equipment is available for use after hours.


The following rules and regulations must be followed by trainees and staff:

  • All new users must go through instrument training from EMCF staff. EMCF users are not authorized to train fellow group members.
  • Any instrument use must be entered in the appropriate log books.
  • If in doubt about using any equipment or chemical please ask the EMCF staff. Any mistake on your part could put you and others at great risk. Proper chemical handling is expected from all users.
  • Do not insert any hazardous materials/specimens inside EMCF microscopes.
  • Closed toed foot wear is mandatory for all lab users.
  • All hazardous chemicals must be used in the hood and hazardous chemical wastes should be disposed off in their respective waste containers stored under the hood in the waste area.
  • In case of a spill it is very important that you immediately inform one of the EMCF staff to help you clean up the spill in an efficient and safe way.
  • Sharpies, rubber bulbs, glass rods and other miscellaneous material present in the hood stay in the hood. They are not to be moved out of the hood under any circumstances. These materials may be contaminated with fixatives.
  • Users are requested to clean up after using any instrumentation in the facility.
  • If you are the last user of the day, please turn off the microscope high voltage and beam and close the center door behind you.
