Light Microscopy Technology Platform
Light Microscopy Technology Platform (LiMiTec)
Welcome to LiMiTec. The LiMiTec represents a state-of-the-art imaging facility bundling light microscopes of the faculty of biology and medical faculty OWL, Bielefeld University.
The Light Microscopy Technology Platform (limitec) at the Faculty of Biology and the Medical Faculty at Bielefeld University is a central service and advisory facility for modern light microscopy. It supports researchers in planning, conducting, and evaluating microscopic experiments—from sample preparation and the selection of appropriate microscopy techniques to image analysis and data interpretation.
The services offered include access to high-performance microscope systems (including confocal and fluorescence microscopy), technical training, as well as individual consultation and workshops. In addition, limitec supports methodological developments and promotes professional exchange regarding innovative imaging techniques. The goal is to enable high-quality, reproducible, and scientifically sound microscopy data and to provide long-term support for research at the faculties.
For technical support please contact Dr. Thorsten Seidel or Dr. Barbara Biermann.

Download of Nutzungsordnung-LiMiTec.pdf
General Instructions: Before starting to use any microscope of the LiMiTec, an introduction to the microscope is mandatory and safety instructions according to GenTSV (safety levels S1 and/or S2) and TROS/OStrV (LSMs and Lightsheet Microscope) are required. Keep the labs clean and pay attention to the waste separation.
For booking the confocal microscopes, request a login once you have been introduced to the microscope. The booking platform is available at https://limitec.biologie.uni-bielefeld.de/account/login/. Booking is possible for up to three weeks in advance. Do not exceed four hours for a single slot and three slots a week Monday to Friday from 8:00 to 18:00, long term experiments should be performed at the weekend or overnight. Avoid gaps between slots. Delete your booking, once it turns out that you are not going to use it. If that happens at short notice, inform other users who booked the microscope that day by email. Keep yourself updated about the users who booked the microscope before and after your slot to ensure proper handover of the system.
Before you start, contact the one who booked it before you to avoid gaps and unnecessary switching off of HBO/HXP-lamps and argon-ion lasers, if they are still needed. Check the equipment and the logbook for obvious damages and reported problems. Report problems in the logbook and also inform the staff. Before you leave, clean all objective lenses you have used. Keep the lab clean and contact the following user. If you are the last user, ensure that the system is properly shut down. If you are the second last user, check if the last user that day shows up.
Copy your data to the servers of the faculty and check the files. Delete the local files the next time you are using the microscope. There is no backup of local files. Data of people who are no longer affiliated with Bielefeld University will be deleted. The same applies for the image processing PCs.
