Central Laboratory of Lorestan University

The central laboratory of Lorestan University was built in the summer of 2013 in order to optimally organize and utilize advanced laboratory equipment and provide easy and equal access to laboratory facilities as well as exchange information between researchers inside and outside of the university.

The laboratory is built in the main site of the university in Kamalvand (next to the Faculty of Science). However, some of the other complex equipment available in other faculties which can be shared are under the supervision of this laboratory.

 This laboratory is supervised by the Vice Chancellor for Research Office and all its services are provided at the rate approved by the university. In addition to providing service to the faculty members and students of Lorestan University, this laboratory is ready to provide laboratory services to researchers and other bodies outside the university.
