Precautions when using a biological microscope
■ Holding the microscope must be the posture of holding the arm with the right hand and supporting the seat with the left hand, and cannot be extracted with one hand, so as not to dislodge the parts or collide them to other places.
■ Hold and place the microscope lightly, do not place the microscope on the edge of the experimental bench, it should be placed 10cm from the edge, so as to avoid tipping over and falling to the ground.
■Keep the microscope clean, the optical and lighting parts can only be wiped with mirror paper, do not blow the mouth and hand wipe or wipe with a cloth, mechanical parts with a cloth.
■Water droplets, alcohol or other drugs do not touch the lens and the mirror stage, if stained should be immediately wiped with mirror paper.
■Place the slide specimen should be aligned with the centre of the aperture, and can not put the slide in reverse, to prevent the slide from being crushed or touching the objective lens.
■To develop the habit of observing with both eyes open at the same time, with the left eye observing the field of view, and the right eye used for drawing.
■Don't remove the eyepiece to prevent dust from falling into the objective lens, and don't disassemble various parts to prevent damage.
■ After use, must be restored to be put back into the mirror box, the steps are: remove the specimen piece, rotate the rotator so that the lens away from the light hole, down the mirror stage, flat reflector, down the light collector (but do not touch the reflector), close the aperture, the pusher back to the position, cover the silk cloth and the outer cover, put back into the laboratory cabinet. Finally, fill in the use registration form. (Note: the reflector should normally be placed vertically, but sometimes because the light collector is not raised to the height it should be, the aperture will be touched when the mirror table is lowered, so it is changed to a flat place).
