The scanning electron microscope and (SEM) and transmission electron microscope (TEM) find their home in the Electron Microscopy Services Laboratory (EMSL). This laboratory provides structure analysis of biological and non-biological samples by light photomicroscopy and the ultra-structure analysis of samples by scanning and transmission electron microscopy.

It houses both the transmission electron microscope (TEM), Hitachi Model H-300 and the scanning electron microscope (SEM), Hitachi Model S-510. Other equipment include the ultramicrotome (Ultracut E), the critical point drying apparatus, the ion sputter and the high vacuum evaporator. EMSL is capable of developing and improving species (biological)-specific sample preparation techniques suitable for magnification using the electron and light microscopy.
