Jiangsu Tongjun explains the daily maintenance method of biological microscope
Place the biomicroscope in a dry, clean room to avoid mold, metal parts, and dust. After the microscope is used, put it back in the box (cabinet), or cover it with a glass cover, plastic cover, and put in the dry agent. Do not disassemble the parts of the biological microscope by yourself; insert the eyepiece or the cover of the lens to prevent the dust from entering from the upper part of the lens barrel; do not touch or wipe the surface of the lens with dust. If there is dust, use a soft brush first. Wipe it off and wipe it with a soft, clean cloth. You can also use a pair of xylene or petroleum fans to wipe the paper, but be careful not to scratch the lens surface. If the lens has mild mildew, if it can't be wiped with the rubbing paper, use a cotton swab to gently wipe the mixture with a little 70% ethanol and 30% B. Biomicroscopes should not be placed with corrosive acids, reduced or volatile chemicals to avoid corrosion and shorten service life. In principle, when observing a liquid-containing specimen, it is usually covered with a cover slip; if the liquid contains corrosive chemicals such as acid or alkali, the perimeter of the coverslip should be sealed with paraffin or vaseline, and then observed. . However, due to the microscopic identification of traditional Chinese medicines, it is often necessary to use such reagents, and it is impossible to seal them. Therefore, special care should be taken to prevent liquid from flowing to the stage and not to be attached to the objective lens. The biological microscope should not be exposed to direct sunlight, nor should it be placed close to the stove or the heating to avoid the degumming, deformation or damage of the lens and the parts caused by the cold and hot changes. The cleaning objective is limited to the outer surface. After the surface of the object is contaminated with the drug, wipe it with a small amount of mirror liquid (do not use ethanol); if the back side should be cleaned, wipe it with a soft brush or use a leather tip to remove dust. After using the oil mirror, the cedar oil on the microscope lens should be wiped clean (can be rubbed with a little xylene in the mirror paper, but the xylene can not penetrate into the lens, otherwise the xylene dissolves the adhesive between the lenses. Can make the lens fall off). Adding mechanical parts is not flexible, you can use fine silk cloth, xylene, less sputum: wipe off rust and greasy (do not use ethanol, because these solvents will erode paint), then use a little liquid stone to lubricate; do not twist the twist tightly To avoid damage.
