2. MICROSCOPE INSTRUCTIONS
The distinct feature of the Microscope is the rotating dual-slide stage
that allows you to easily compare two specimens.
2.1. First, unscrew the battery door at the back of the stand; install 2 x
AA batteries matching the polarities indicated and then close the
battery door.
2.2. Check the LED light by switching the light switch to Power ON:
when the light can be seen through the eyepiece, the microscope
is ready for observation.
2.3. Put the prepared slides in parallel next to each other on the stage
and _x it in place with the clips.
2.4. Now, decide what magnification to use. The greater the length of
the objective lens the greater the magnification. Observation is
generally made starting at a low setting.
2.5. In order to change the magnification; turn the revolving turret until
you feel a click.
2.6. Using the focusing knob, lower the lens as close as possible to the
prepared slide without actually making contact. Then, while
looking through the eyepiece, turn the knob in the opposite
direction until the image comes into focus.
2.7. You may tilt the microscope body to enable better observation.
2.8. The light source lamp requires 2 "AAA" batteries (not included).
3. HOW TO MAKE PREPARED SLIDE
If the given sample is not thin and transparent, it cannot be observed
by the microscope as the light from the reflector or the light source
does not pass through it. Fibers, pollen, wool, or salt can be observed
easily and a cover glass is optional.
Clear samples are stained first with a drop or two drops of methylene
blue, Eosin or other dyeing solutions (not included) available on the
market. (Note: These are dyeing solutions and therefore could cause
staining of clothing, carpets, and fabrics.
Special care should be taken when handling these solutions).
3.1. Temporary mount: Wipe the slide and cover glass clean. Slice a
thick sample with the micro-slicer (Note: This process should be
under an adult's supervision. The blade is very sharp and has to
be handled with extreme caution). Pick up the sample with
tweezers and put it on the centre part of the glass slide.
Put one drop of water on the sample with the needle that comes
with your kit.
3.2. Permanent mount: Proceed as above, however, before covering
the slide with the cover glass, add a few drops of gum media (not
included in the set, but available from store) or Canada balsam
solution or transparent adhesive glue with a dissecting needle to
the slide. Push down on the cover glass with tweezers to _x it in
place and leave to dry for a day.
4. CAUTION FOR HANDLING
4.1. The vital part of the microscope is the lens. Therefore, sufficient
care must be taken in handling the lens. If the lens gets dirty or
dusty; wipe the lens surface with a clean lens tissue or soft cotton
cloth. Do not rub the lens with a finger or dirty cloth, etc.
4.2. After the microscope set is used, it should be placed back into the
storage case to prevent dust from infiltrating.
4.3. Microscope should be stored in a moisture free location. Moisture
buildup on the light will cause a reduction in light intensity.
4.4. When a microscope is not used for a long period of time, remove
the batteries.
