The EM lab provides support for research work in the field of soft biological tissues as well as hard tissues. The facility can be used to conduct research work in the field of material science such as nano composite materials and elemental analysis of organic and inorganic samples.

Scanning Electron Microscope (SEM)

The SEM at EM lab is FEG-SEM from Zeiss with a Gatan 3 View 2XP system. It has two SE detectors and 2 BSD detectors that can be used to produce high quality images. A EDS detector with large detector head from Bruker is installed to conduct detailed elemental analysis and mapping.

Transmission Electron Microscope (TEM)

The TEM at the EM lab is a CM 120 BioTwin from Philips.

We offer preparation of tissue for electron microscopy and embedding in Lowicryl HM20, electron microscopy of cells and intact tissue with a resolution at the nanometer level, and immunogold electron microscopy
