SEM Facility


SEM facility at National Agriculturally Important Microbial Culture Collection (NAIMCC), NBAIM, Mau

NAIMCC has developed the state-of-art facilities for morphological characterization of agriculturally important microorganisms. The facilities include compound light microscope, stereo microscope, fluorescence microscope, confocal laser microscope and scanning electron microscope (SEM). SEM is a useful technique for producing very high-resolution images of a sample surface, revealing details of less than 1 nm in size. SEM micrographs have a large depth of field yielding, a characteristic of three dimensional appearances useful for understanding the surface structure of a sample. An automated SEM Microscope (SEM S-3400N) equipped with computerized eucentric in 5-axes motorized stage used for imaging of microbial cultures. Highest magnification of about X5 – X300000 and resolution of about 10 nm at 3 kV and 3.0 nm at 30 kV can be achieved. Scanning electron microscopy is used in systematics and taxonomic studies, clinical laboratories, environmental analyses (e,g, biofilm formation and characteristics) and in agriculture and allied sectors.
