Cheap Biological Microscopes Product Introduction The binocular microscope with halogen lamp are available in a variety of specifications. Before use Operation 1. Insert the eyepiece into the eyepiece tube and screw the objective lens into the nose lens in the order of different magnification from low to high. Then place the sample on the stage, fix it in place with tablets, and move it to the center of the stage. 2. Turn on the power switch and adjust the brightness form dark to bright slowly. After working, you must adjust the brightness to a little dark before you turn it off. 3. Observe the specimen from lower magnification objective firstly and move the specimen to the center of view field, then rotate higher magnification objective. You many use the fine focusing knob to obtain the clear image. When 100X (s.oil) objective is used, you should fill up with cedarwood oil (without bubble) between the front of objective and the specimen surface. After working, it should be wiped with a few xylene immediately. 4. In order to obtain bright and clear image, the illumination must be adjusted. When different objective is chosen, you should adjust the iris diaphragm of the condenser and different brightness of the light. 5. When the lamp needs to be replaced, turn off the power switch and replace it after the lamp is cooled. Note: the contact must be firm and the filament center should be adjusted. 6. If you use a camera or video accessory, you can insert the accessory into the tube of the microscope's trinocular head, and then adjust the tube until the image is clear enough.

Place the specimen slide on the stage, position the spot of the slide you wish to observe to the center hole on the stage and clamp it with slide clips. 2. Mount objectives on revolving nosepiece and eyepiece on eyepiece tube respectively. 3. Turn reflecting mirror to the source of light until the light illuminated into the eyepiece tube and the field of view becomes visible, then adjust the aperture of iris diaphragm(disc) to secure clear image. 4. When focusing, first adjust focus wheel forward to lower the main tube until the objective gets close to the specimen slide, so as to avoid any possible damage.Then start to observe the eyepiece by adjusting the focus wheel until a sharp image is obtained. 5. The stand can be adjusted when necessary to obtain the best angle for the light source and for the comfort of observation. Product feature and application The binocular microscope series with halogen lamp has stable frame and can fit monocular, binocular, trinocular head on it. Double layer mechanical stage with adjustable long handle and coaxial coarse/fine focus knob make the operation easily.It is provided with high quality achromatic objectives, wide field eyepieces and halogen lamp adjustable brightness, which guarantee the best image. It's both excellent in performance and moderate price. It is used widely for clinical examination, teaching demonstration, bacteioscopy and cytoscopy in colleges and universities, medical and health establishments, research institutes and department of forestry and agriculture. Maintenance and precautions 1. Carefully open the package to avoid damaging the lens or accessories. 2. Operate correctly, and put the dust cover on the microscope after work. 3. Don't dismantle the instrument rashly besides the replaceable lest the correct position should be breached. 4. Keep the instrument in dry and cool place and away from the pollution and corrosion. 5. Please send the instrument to the special repair shop if it goes out of order. 6. When the objectives and eyepieces won't be used for a long time, please place them into a dry box, and put the dust cover onto the microscope.Cheap Biological Microscopes website:http://www.shenmateaching.com/microcopes/biological-microscopes/
