Maintenance of optical microscope
2. Maintenance and maintenance work
1. Daily maintenance
(1) Moisture-proof optical lenses are prone to mold and fog. Mechanical parts are prone to rust when exposed to moisture. One to two bags of silica gel should be placed in the microscope box as a desiccant.
(2) Dust falling on the surface of dust-proof optical components not only affects the passage of light, but also generates large stains after being magnified by the optical system, which affects observation. Dust and sand falling into the mechanical parts will also increase wear and tear, causing movement to be blocked, and the harm is also great. Take care to keep the microscope clean.
(3) Anti-corrosion microscopes cannot be placed together with corrosive chemical reagents. Such as sulfuric acid, hydrochloric acid, strong alkali, etc.
(4) Heat protection to avoid thermal expansion and contraction of the lens from degluing and falling off. Therefore, the biological microscope should be placed in a dry, cool, dust-free, and non-corrosive place. After use, wipe it clean immediately, cover it with a dustproof and breathable cover or put it in a box. When the microscope is not in use, cover it with a plastic cover and store it in a dry place to prevent dust and mildew. Store objectives and eyepieces in a container such as a desiccator, protected from desiccant.
2. Maintenance of the mechanical system Sliding parts: regularly apply some neutral grease paint and clean the plastic surface: stubborn stains can be cleaned with a soft detergent, and it is recommended to use a silicon cloth. Plastic parts: Clean with a soft cloth dampened with water. Note: Do not use organic solvents (such as alcohol, thinner, etc.). Because it will corrode machinery and paint, causing damage.
3. Maintenance of the optical system Cleaning of the lens After use, gently wipe the eyepiece and objective lens with a clean and soft silk cloth. Condenser and reflector only need to be wiped clean. If there are more stubborn stains, use long-fiber absorbent cotton or clean fine cotton cloth dipped in a little xylene or lens cleaning fluid to wipe it, and then dry it with a clean and soft silk cloth or blow dry with a blower.
Note: The cleaning solution must not penetrate into the lens of the objective lens, otherwise it will damage the lens of the objective lens. Pure alcohol and xylene are flammable, and special care should be taken not to ignite these liquids when turning the power switch on or off. The treatment method for moldy and foggy objective lenses and eyepieces Prepare 30% absolute ethanol + 70%, and separate different lenses into desiccant containers. It is best to use soft things such as cotton swabs, gauze, and soft brushes to wipe them. The oil mirror should be cleaned at that time. Especially the 100X oil lens, if it is not handled properly, the front piece is easy to be soaked in oil or glued. The eyepiece can be removed and cleaned by yourself. Be careful not to install the 16X eyepiece upside down. The concave surface of the front piece is on top. Do not remove the objective lens casually. Note: When scrubbing the lens, do not use too much force to prevent damage to the coating layer. Generally, it is best to maintain it once every 2 months. When there are many microscopes, each lens must be labeled to avoid confusion.
4. Regular inspection In order to maintain stable performance, it is recommended to do regular inspection and maintenance.
