SAFETY NOTES
1. Open the shipping carton carefully to prevent any accessory, i.e. objectives or eyepieces, from
dropping and being damaged.
2. Keep the instrument out of direct sunlight, high temperature or humidity, and dusty environments.
Ensure the microscope is located on a smooth, level and firm surface.
3. If any specimen solutions or other liquids splash onto the stage, objective or any other component,
disconnect the power cord immediately and wipe up the spillage. Otherwise, the instrument may be
damaged.
4. All electrical connectors (power cord) should be inserted into an electrical surge protector to prevent
damage due to voltage fluctuations.
5. LED LAMP & FUSE REPLACEMENT -- CAUTION: the glass housing of the lamp may
be hot. DO NOT attempt to change the lamp before it is completely cooled For safety
when replacing the LED bulb or fuse (ONLY replace with the same size, type and rating of
original LED bulb or fuse), be sure the main switch is in the off position, disconnect the
power cord from outlet, and replace the LED bulb or fuse. Reconnect the power cord and
turn unit on.
6. Confirm that the input voltage indicated on your microscope corresponds to your line voltage. The
use of a different input voltage other than indicated will cause severe damage to the microscope.
NOTE: Always plug the microscope power cord into a suitable grounded electrical outlet.
A grounded 3-wire cord is provided.
CARE AND MAINTENANCE
1. Do not attempt to disassemble any component including eyepieces, objectives or the focusing
assembly.
2. Keep the instrument clean; remove dirt and debris regularly. Accumulated dirt on metal surfaces
should be cleaned with a damp cloth. More persistent dirt should be removed using a mild soap
solution. Do not use organic solvents for cleaning.
3. The outer surface of the optics should be inspected and cleaned periodically using an air bulb. If dirt
remains on the optical surface, use a soft, lint free cloth or cotton swab dampened with a lens
cleaning solution (available at camera stores). All optical lenses should be swabbed using a circular
motion. A small amount of absorbent cotton wound on the end of a tapered stick such as cotton
swabs or Q-tips, makes a useful tool for cleaning recessed optical surfaces. Avoid using an
excessive amount of solvents as this may cause problems with optical coatings or cemented optics
or the flowing solvent may pick up grease making cleaning more difficult. Oil immersion objectives
should be cleaned immediately after use by removing the oil with lens tissue or a clean, soft cloth.
4. Store the instrument in a cool, dry environment. Cover the microscope with the dust cover when not
in use.
5. UNITRON®microscopes are precision instruments which require periodic servicing to maintain
proper performance and to compensate for normal wear. A regular schedule of preventative
maintenance by qualified service personnel is highly recommended. Your authorized UNITRON®
distributor can arrange for this service.

INTRODUCTION
Congratulations on the purchase of your new UNITRON®microscope. UNITRON®microscopes are
engineered and manufactured to the highest quality standards. Your microscope will last a lifetime if
used and maintained properly. UNITRON®microscopes are carefully assembled, inspected and tested
by our staff of trained technicians in our New York facility. Careful quality control procedures ensure each
microscope is of the highest quality prior to shipment.
UNPACKING THE COMPONENTS
Your microscope arrived packed in a molded shipping carton. Do not discard the carton: the shipping
carton should be retained for reshipment of your microscope if needed. Avoid placing the microscope in
dusty surroundings or in high temperature or humid areas as mold and mildew can form.
The components of the 12100 Polarizing Microscope are shipped “double-boxed” -- inside the inner
cartons the microscope and its components are further protected by foam forms.
IMPORTANT: When lifting and moving the microscope, hold it by one of the microscope frame’s curved
vertical arms with one hand and place your other hand under the base of the frame. NEVER hold
the stage, focus knobs or eyepiece tubes when lifting or moving the microscope.

UNPACKING THE COMPONENTS (continued)
IMPORTANT
A shipping clamp secures the microscope’s focusing mechanism during transportation.
Once the microscope mainframe has been removed from the shipping carton and foam support,
the clamp must be removed before proceeding further.
The clamp is accessible by removing the Illuminator Housing at the base of the mainframe.
To remove the clamp:
Grip the finger grooves on the sides of the housing
and slide the housing off the microscope frame.
Use the hex key tool provided to remove the three
screws securing the gold-toned clamp.
NOTE: Retain this clamp and screws for reuse in
the event the microscope is reshipped.
Replace the Illuminator Housing, making certain it
is pushed fully back onto the microscope frame.

ASSEMBLY
Mounting The Viewing Head
Bertrand/Analyzer assembly is preinstalled onto
the microscope frame. The viewing head is
mounted to the Bertrand/Analyzer assembly. Note
that the viewing head has a registration pin on its
mounting flange. This pin must engage the
corresponding slot on the top flange of the
Bertrand/Analyzer assembly.
Secure the viewing head by tightening the hex type
set screw on the right side of the Bertrand/Analyzer
assembly.
Mounting The Condenser
The condenser incorporates a registration pin on
its mounting flange. This pin engages a
corresponding groove in the condenser mounting
bracket.

Eyepiece Installation
(Refer to photos on left)
LEFT: Turn the top of the Standard eyepiece (no
reticle) clockwise until it stops and is in its lowest
position.
Insert the eyepiece into the left eyepiece tube by
aligning the notches on the eyepiece slightly to the
left of the tabs on the eyepiece tube; rotate the
eyepiece clockwise until the tabs engage the
notches (it will stop rotating when engaged).
RIGHT: Turn the top of the Measuring eyepiece
(with reticle) clockwise until it stops and is in its
lowest position.
Before inserting the eyepiece, look through the
eyepiece to determine the correct orientation of the
scale (i.e., it should be horizontal and readable).
Insert the eyepiece into the right eyepiece tube by
aligning the notches on the eyepiece slightly to the
left of the tabs on the eyepiece tube; rotate the
eyepiece clockwise until the tabs engage the
notches (it will stop rotating when engaged).
NOTE: Only one orientation on the right
Measuring eyepiece is correct: the one in which
the numbered scale is horizontal when you look
through the eyepiece.
