Preparation
Please read this section completely before using your microscope. Study the
Components diagram (page 2) to learn the various parts of the instrument.
When carrying the microscope hold the
microscope by the “arm” and have the other
hand firmly under the “base” for support.
Always set up your microscope on a smooth
surface, such as a desk or table.
Invert the microscope (taking care the
eyepiece does not fall out) to reveal the
battery compartment. Open the compartment and insert 3 AA Batteries (not
included) as indicated. (Base of battery
—
negative end
—
goes against the spring.)
Replace the battery compartment cover.
Before using the scope
,
practice slowly turning the focusing knob (you can use
either knob on the left or right side of the scope) and watching the stage move
without looking through the eyepiece, this will help to familiarize yourself with
the direction you should turn the knob to move the stage closer to the objectives.
The
My First Lab
TM
Duo-Scope
™
has the
capability to illuminate the
specimen from the top or
the bottom. Notice the
power switch located at the
back of the scope. This is a 3 way switch to operate either the top light, the bottom
light, or set to the off position.

Some Ideas for Observation
Onion Cells – Mitosis
Mitosis
is the process where cells separate into 2 identical cells.
1.
Take a small piece from the inside of an onion (approx. ¼ - ½ inch)
2.
Use the forceps (from accessory set); peel off the membrane from the
underside (the rough side).
3.
Place the membrane flat on a microscope slide, and then add one/two drops of
blue stain. Please wait for 2 to 3 minutes for the onion to absorb the stain.
Caution:
Protect surfaces & clothing when using stain!
4.
Using the transfer pipet rinse the excess stain with water.
5.
Add one thin cover glass onto the slide (surface of onion membrane). Make
sure there are no air bubbles underneath.
