Biological analysis instruments

Confocol Microscope
	Model: Nikon Digital Eclipse C2Si, Tokyo, Japan Description: Confocal microscopy is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of adding a spatial pinhole placed at the confocal plane of the lens to eliminate out-of-focus light. It enables the reconstruction of three-dimensional structures from the obtained images.
Stereofluorescence Microscope
	Model: Olympus SZX16 ,Tokyo, Japan Description: The SZX16 is designed for advanced research and is suitable for oblique and bright field illumination. Its maximum numerical aperture (NA) of 0.3 produces a resolution of 900 linepairs per millimeter, enabling more sample information to be gained efficiently. The large zoom ratio of 16.4:1, combined with the comprehensive range of parfocal objectives with excellent working distances, allows easy switching between a macro- and micro-view. Imaging of the whole organism down to fine microscopic and individual cell structures becomes an easy task with an optical system that provides a natural, distortion-free view.
