Introduction: The microscope is a precision instrument. It should be used strictly in accordance with the operating procedures. What should you pay attention to during the use of the microscope?
(1) When taking a microscope, one must hold the mirror arm and one hand to hold the mirror seat, close to the chest, and lay flat on the flat end. Do not pull one hand to prevent the parts from falling off (especially the eyepiece is easily slipped off).
(2) Do not remove the eyepieces at random to prevent dust from entering the lens barrel. Do not remove the parts to prevent damage.
(3) When using, strictly follow the steps, familiar with the performance of each component of the microscope, master the relationship between the rotation direction of the coarse and fine adjustment knobs and the lifting and lowering of the barrel. When the coarse adjustment knob is turned down, the eyes must look at the object lens.
(4) When covering a temporary specimen with a liquid, cover the tablet. Do not use tilted joints to avoid liquid contamination of the lens and the microscope.
(5) The coarse and fine adjustment knobs must be used in conjunction. The fine adjustment knob cannot be over-rotated in a single direction. When adjusting the focal length, the lens barrel must be lowered from the side to avoid damaging the specimen and the lens.
(6) Observe specimens with a monocular microscope. Open both eyes simultaneously. Observe the object image with the left eye. Use the right eye for drawing. Adjust the focal length with the left hand and move the specimen or drawing with the right hand.
(7) It is forbidden to unscrew or exchange any parts such as eyepieces, objective lenses and condensers.
(8) After the microscope is used, lower the stage first, remove the slide specimen, and put it back in place. Rotate the converter so that each object lens is not facing the light hole, and then rise the stage, so that the lens is fixed on the stage, the mirror mirror is vertical, and the condenser lens is lowered. Finally wipe the parts, check the parts for defects, and then put it back in the mirror box.
Car wax is a traditional car paint care. Car wax is mainly composed of natural wax or synthetic wax, which can increase the brightness by penetrating into the gaps of the paint surface to make the surface smooth. Traditional car waxing is mainly for light protection. Now, with the development of car beauty industry, car waxing has been given a new connotation, that is, the appearance and increasingly extensive application of grinding wax.
Car wax is a type of product used to protect and enhance the appearance of a car's exterior. It is typically made from a blend of natural waxes, such as carnauba wax, and synthetic polymers. Car wax can be applied to the paint, chrome, and other exterior surfaces of a car to create a protective barrier against UV rays, water, and other environmental contaminants. It can also help to restore the shine and luster of a car's finish, making it look newer and more attractive. There are many different types of car wax available, including liquid, paste, and spray-on varieties, each with their own unique properties and benefits.
