We are open for sample drop-off and trained users.

Microscope time may be scheduled only by trained, independent users. To be able to provide a safe working environment and keep physical distance, we ask all users to be patient and respectful and to get familiar with our new guidelines and procedures before using the EM Facility. EM staff will be working in 2 shifts; Maria and Anja will be in the lab on Mondays, Wednesdays and Fridays. Louise and Peg will be in the lab Tuesdays & Thursdays. 

Covid-19 guidelines:

  • Masks must be worn at all times.
  • Keep 6 ft away from other users.
  • Respect posted signs. 
  • Use the sign-up calendars to reserve time on the microscopes, sputter coater and glow-discharger.  
  • To use the HPF, negative staining bench or any other equipment please e-mail the core director. We can not accomodate drop-in visitors at this time.

Sample drop off:

  • Clearly label your samples the same way as you labeled them in the service request form. 
  • When you arrive to drop off your samples follow signs and wait your turn in the hallway if someone is ahead of you. Leave your samples in the labeled area in the fume hood and exit using the other door.

Equipment and lab use:

  • We ask all users to do negative staining preparations in their own lab whenever possible.
  • We have one bench in the lab set up for negative staining, please e-mail us ahead of time to use it.

  • Each microscope will have a disinfection protocol posted in the room. Please adhere to proper disinfection protocols for all touch surfaces.
  • Users will be required to wear a face mask at all times. 
  • Gloves and Hand sanitizer will be available at every microscope.
