Introduction to the Maintenance of Biological Microscopes and Troubleshooting of Common Faults
A biological microscope is a precision optical instrument commonly used in biological teaching experiments, consisting of a mechanical system and an optical system.
The mechanical system includes: the transmission part of the lens barrel, the rotating part of the objective lens, the stage, the conversion part of the press clamp and the shutter, the rotating part of the frame and base, etc.
The optical system includes: eyepiece, objective lens, condenser lens, and reflector.
1. Maintenance and upkeep
(1) Overall maintenance: The biological microscope should be placed in a dry, cool, dust-free, and non corrosive place. After use, it should be wiped clean immediately and covered with a dust-proof breathable cover or placed in a box.
(2) Maintenance of mechanical systems: After use, wipe clean with a clean cloth and regularly apply some neutral lubricating grease to the sliding parts. If there is serious pollution, it can be washed with gasoline first and then wiped dry. But never use alcohol or ether for cleaning, as these reagents can corrode machinery and paint, causing damage.
(3) Maintenance of optical system: After use, gently wipe the lenses of the eyepiece and objective lens with a clean and soft silk cloth. When there are stains that cannot be wiped off, you can use a long fiber degreasing cotton or a clean fine cotton cloth dipped in a small amount of dimethyl benzene or lens cleaning solution (3 parts alcohol: 1 part ether) to wipe them off. Then dry it with a clean and soft silk cloth or blow dry with a hair dryer. It should be noted that the cleaning solution must not penetrate into the interior of the objective lens, otherwise it will damage the objective lens. The spotlight (only available for XSP-13A and 16A models) and reflector only need to be wiped clean after use.
2. Troubleshooting of common faults
(1) The self sliding of the lens barrel: This is one of the common malfunctions that occur in biological microscopes. The solution to the microscope with a shaft sleeve structure can be divided into two steps.
