The Faculty of Materials Science and Engineering has a range of laboratories for both teaching and research. The laboratories have equipment for processing of many types of materials and analyses, testing and investigation. These modern test facilities are also available for routine testing and inspection of materials on commercial basis. The following lists the laboratories currently housed within the faculty along with a brief description of the major instruments available:

FMCE has recently established an Atomic Force Microscopy (AFM) laboratory for materials characterization especially at nano scale level. AFM is an advance characterisation technique capable of performing many kinds of materials analysis i.e. high resolution imaging, magnetic characterization, nano lithography, nano indentation etc. The AFM lab is useful both for the teaching and research work.
