simple staining How to Focus the Microscope Turn the revolving nosepiece to 10 magnifying lens Move the stage up the condenser to the top position and close iris diaphragm half way Put the slide on the slide holder on the stage. Microscopes are delicate and expensive instruments they should be handled with utmost care Before you use the microscope your instructor will explain its proper use Following are rule s that will protect the microscope and insure that you can make m This model comes with color corrected infinity optical system (CSIS), a movable large working distance condenser, 45 degree inclined trinocular head, high eye-point Plan eyepieces, infinity long working distance PLAN achromatic objectives and infinity long working distance PLAN phase contrast objectives. This microscope offers nine brightfield magnification powers, 40X, 60X, 100X, 150X, 200X, 300X, 400X, 600X & 900X, and six phase contrast settings, 100X, 150X, 200X, 300X, 400X & 600X. Its 30 watt adopt Kohler illumination system was designed for 90-240V wide voltage power supplies. Laltu. Chandra. Indian Institute of Technology Jodhpur. chandra@iitj.ac.in.
