Maintenance
Instruction Manual
1 Always cover your microscope with the dust cover when not in use.
Model pictured:
2 When cleaning the lenses, use lens paper or a cotton swab dipped in lens cleaning
M-Series LabScope
solution.
Not all features available on all models see back page for model specifications.
3 Excess oil should be cleaned off your 100x objective and stage at once. An alcohol pad is best for removing oil
from the stage and on the other metal parts, but is not recommended for use on the lenses. Use lens cleaning
solution and lens paper to clean off your objectives.
4 Dust in the nosepiece or ocular tubes should be blown out using filtered air. Canned air dusters work well for this job.

Operation
Note: If your microscope has been exposed to cold weather, please allow time for all the parts
to come to room temperature before switching on the power. Excess cold can fog the lenses
and may cause the lamp to fail.
1 Once you have assembled all the parts, plug the power cord into the appropriate AC outlet.
2 Turn the light on using the black rocker switch on the back of the base. Next adjust the light intensity using the
adjustment knob located on the left side of the scope. Note: Rapid, repeated changes in light intensity will
dramatically shorten the life of the quartz halogen lamp.
3
In order to become familiar with the controls, choose a specimen slide with which you are familiar. For example, an
old hematology slide or a commercially prepared slide. Place the slide into the slide holder by pushing back on the
thumb guard to open the slide finger. The slide finger closes slowly to eliminate the possibility of chipping the corner of
your slide when it closes.
Move the slide to the center of the stage, by turning the stage and slide control knobs, just below the stage. These
4 knobs allow you to move the slide in the X-Y axis (forward/backward and left/right).
Assembly
5
1 The M2/M5 LabScope is packaged in two sections. The body of the microscope (including the objectives, filters, oil,
fuse and bulb) is in one large box and the head (including eyepieces and eye guards) is packaged in the smaller
box.

3
Remove the body of the microscope and place it on a sturdy, dust-free surface. Install the objectives in such a way
that when you turn the nosepiece clockwise, you are moving from the 4x, to 10x (to 20x-M5 only) to 40x, and finally
the 100x objective.
6 Once you are comfortably seated, look into the oculars and move the eyepiece tubes together or apart until you see
only one complete circle of light. You have now adjusted your interpupillary distance.
Using the 4x or 10x objectives and the coarse and fine adjustment knobs bring the field of view into focus. Now move
7 the 40x objective into place. You will feel a “clicking” action when the objective is seated properly. Again, focus the
best image. You will now be in the middle of the focus range. You may have to adjust the iris diaphragm (on the
condenser) for the best contrast.
Remove the microscope head from the Styrofoam carton and pull off the protective covers from the eyepiece tubes
4 and head mount. Insert the head mount into the upper arm of the body. Using the thumb screw, secure the head in
place. Note: Do not over-tighten.

Insert the 10x eyepieces. Attach the power cord.
Instructions for installing the optional trinocular tube:
2 Remove the metal cap on the top of the microscope head by inserting the Allen wrench (provided) into the screw on
opening.
tighten the tension control ring (located on the right side of the microscope between the coarse adjustment and the
body of the microscope). If the coarse focus is hard to turn, you may choose to loosen the friction adjustment.
Stage Stop: To help prevent the stage from hitting the objectives, this scope is equipped with an adjustable stage
10 stop. Rotate the 100X oil objective into place and put a slide into the slide holder. Slowly raise the stage, stopping
Tighten the screw on the side of the tube with the Allen wrench.

Lamp Replacement
Caution: Unplug the microscope and let it cool down if recently in use before
opening the base of the microscope. When handling a new quartz lamp, be sure
not to touch the new lamp with your fingers. Oil and sweat on the bulb may cause
it to explode or shatter as it heats up.
Turn the scope on its side. (We recommend that you place a cushion or soft cloth under the microscope to protect
against damage.) Locate the lamp compartment door; you will notice a black plastic knob near the front. Turn the knob
to open the door. The lamp compartment door may now be swung open to reveal the lamp plugged into its base.
Gently pull the old bulb out and discard.
Using a lint-free tissue or piece of cloth to hold the new lamp, install the bulb. Swing the lamp compartment door closed
and turn the black knob to lock. Carefully return the scope to the upright position and plug the microscope in the
appropriate AC outlet. The electronics on the M-Series LabScope will support up to a 35watt/ 12V bulb.
Diopter Adjustment: Since you are using a binocular microscope, you have to adjust for the normal difference in vision
between your two eyes. This is a simple but critical adjustment! Close your left eye and look into the right ocular with
your right eye. Adjust the fine focus to give you the best image. Now look at the ocular tube on the left. You will see
that the left ocular tube has a built-in adjustment ring. Now close your right eye and look with your left eye into the left
ocular. Using the diopter adjustment ring on the left ocular tube, adjust the focus until you see a clear, focused field.
9 Friction Adjustment: With repeated use and wear, the stage may drift out of focus. If this happens, you need only to
the side of the cap. Loosen the screw and remove the cap.
3 Insert the trinocular tube (eyepiece or c-mount, depending on how you ordered your microscope) into the
Open the iris diaphragm on the Abbe condenser (controlled by the black ring on the condenser). Insert the filter of
your choice on top of the condenser lens on the base. Note that many customers prefer to use the blue filter for
routine use.
when the slide makes contact with the objective. Now, turn the stage stop lever in a clockwise direction toward you.
The stage stop lever is located on the left side of the microscope between the coarse adjustment and the body of
the microscope.
Parfocality: All LW Scientific microscopes are manufactured to be parfocal – meaning that when you change
objectives or magnification, the specimen will remain very close to being in focus, with only a fine adjustment
needed. The M-Series LabScope is “preset” for parfocality.
Your M-Series scope has an iris in the sub-stage condenser, and another iris in the base Koehler condenser (if
12 equipped). Set the base iris to the widest open setting. The sub-stage iris should then be set, using the scale on the
side of the sub-stage condenser, to match the aperture of the objective for maximum resolution under each objective
power. For example, when using the 4x objective, the sub-stage iris should be set to 0.1, which is nearly closed. For the
10x objective, set the iris to .25. For the 40x objective, set the iris to .65. Under the 100x objective, the iris should be set
to 1.25, which is wide open.
You are now ready to use your M-Series LabScope – thank you for choosing LW Scientific!
