Student microscope is designed for tertiary institutions and primary and secondary schools, which is convenient to observe biological slices, biological cells. bacteria and living tissue culture, fluid precipitation observation, and research. It is widely used in teaching demonstration, biochemical experiments, clinical research ect.

How to Use

Open the package and take out the microscope, insert the desired eyepiece, put on the rubber eyepiece cover, and tighten the anti-theft screws (ensure the eyepiece free rotation)
Take off the objective cover, switch on. Select the appropriate light source (top light or bottom light).
Put the objects in the center of a stag, then adjust the focusing knob. Observe the right eyepiece to make the image clear (depending on the situation to select brightness). Adjust the left diopter again to make the left and right images both clear.
Rotate objective cover. select appropriate objective multiple.
When needed, can be screwed into an auxiliary objective at the bottom of the lens cover.
If feel the torque is too tight when using, rotate the focusing knob arduously; Or the torque too light, observing head auto-drop down, please use a wrench to adjust the torque of the inside focusing knob to be appropriate.

Maintenance and Care

Whether the instrument is in use or storage should avoid dust, humidity, cold, heat, or PH steam.
Chemicals shall not be placed near the instrument, even more in the microscope cabinet (except desiccant).
When not in use, the whole instrument should be covered by a dust cover to keep it clean. If there is dust on the lens surface, don’t wipe it by hand, only by brush.
If there is dust on the lens surface, can use clean old linen or cotton cloth dipped in a small amount of pure alcohol and ether mixture (1:1), or benzoline and xylene to wipe gently. Don’t touch the lens surface by finger.
Due to time, grease on gear, rack, sliding groove surface, and sliding cylinder will bond with dust into dirt or hardened, leading to rotating the coarse knob difficultly, can use xylene to clean, then add a little acid-free animal grease or acid-free Vaseline, can’t use another grease.
When microscope and eyepiece are not in use, should be covered with cloth or glass to prevent dust.
