Biological microscope use
The trinocular biological microscope XSP-8CA is one of the independent production products of Shanghai Xuanlun. It is 40-1600 times magnified by the principle of three-eye observation head four-hole converter. It can be connected to CCD and digital camera.
This series of biological microscopes is used for general biology, bacteriology research, clinical trials and experiments in teaching in various medical institutions, laboratories, research institutes and universities. It is different to choose different magnification objective lenses and different magnification eyepieces. Total magnification, the magnification range is 50 times to 1600 times
Folding use
1. Place the specimen on the workbench and press it with the sliced ​​tablet.
2. The objective lens of each magnification is sequentially loaded into the objective lens converter, and the eyepiece is inserted into the eyepiece tube.
3. When observing, first use the low magnification objective lens to find the object to be observed, then move the observed object to the center of the field of view, and then convert it to a high magnification objective lens.
4. When focusing, generally adjust the objective lens with the coarse focus knob to see the outline of the specimen, and then adjust it with the fine focus knob until the object is the clearest. When using a high-magnification objective lens, it is best to adjust from bottom to top to avoid damage to the lens caused by touching the slice.
5. Rotate the mirror so that the illumination light enters the lens barrel to obtain a bright object, and then adjust the aperture size of the aperture to obtain the clearest image.
Folding maintenance
1. After use, the instrument should be returned to the wooden box and placed in a dry, clean, well ventilated place with no acid or alkali vapor.
2, the microscope has been carefully examined and college, the objective lens and eyepieces do not disassemble by themselves, if there is any dust, first blow it with a blower ball, then remove it with a soft brush. The oil can be wiped with a clean fine cloth dipped in xylene.
3. If the mechanical part of the microscope name is contaminated with dust, the dust should be removed, and then wiped clean with a dry and clean soft cloth. The lacquer-free part should be coated with a thin layer of non-corrosive lubricant.
4. If the coarse focusing mechanism is too loose or too tight, it can be adjusted with a special small wrench (placed in the objective lens box). The direction is locked and the counterclockwise direction is relaxed.
5. The objective lens must be placed in the objective lens case to prevent damage and contamination.
6. When using the 1002 objective lens, add a little cedar oil between the lens and the slice. After use, immediately wipe the oil with a clean soft cloth dipped in xylene.
7. In order to prevent the time-lapse objective lens from breaking the slide glass, there is a positioning screw for the limit position, but the limit screw can only limit the minimum point of the coarse adjustment. When the fine adjustment drops to a certain position, the object may still be pressed to the slice. Still need to pay attention.
