3D-EM - our offer
The 3D-EM Core Facility has high-end electron microscopes and sample preparation equipment for biological samples. The facility is primarily training-based, in that we will train you to operate the microscopes and instruments so you can collect your own data.
For data collection by staff, an additional 700 SEK/hr fee is charged on top of instrument fees. All our available instruments are listed below, as well as information regarding pricing and training.

Access and booking
Only registered users can have an access to the facility. Registration is to be completed on the 3D-EM Core Facility iLab site and must be approved by PI of the user. The PI provides each user with project number to facilitate monthly payment via iLab.
Teaching and training
We will arrange courses and workshops periodically. However, users are encouraged to receive individual TEM training followed by a test on the 120 kV Talos microscope following which, we will grant them card access to the facility. Once you have passed the test on the Talos and have access to the facility, you can be trained on other instruments as needed for your project.
