Lx 500
The Lx 500 is a research microscope with a modern design and the latest in optical and mechanical advancements.
Designed for professionals as well as clinicians, the microscope offers many features and functions for a diverse
set of applications. Here are some of the benefits of the Lx 500.
Extra clarity and contrast is provided through a 360
° rotatable Binocular/ Trinocular body inclined at
30
° with IPD adjustment. A 0-30° tiltable ergonomic head is provided for adjustable viewing height according
to the user's height, enhancing the user's comfort.
The stand consists of a ball bearing, low-friction focusing mechanism.
The sturdy, modern design provides a high degree of comfort and stability.
The high-powered objectives are spring loaded to prevent accidental damage to specimen slides.
The reverse angle quadruple nosepiece has a comfortable ribbed grip for easy rotation that also
safeguards the turret system against any damage. All positions are par-centered and parfocalised ensuring the
highest level of accuracy.
The ball bearing mechanical stage provides a smooth surface over a 76 x 50 mm area with spring loaded
stage clamps for retaining the specimen at the desired position. A 0.1 mm vernier scale aids in measurement.
High power illumination is delivered through our Universal Power Supply operable within a range of
100V - 240V AC input. This ensures continuous operation even under flactuating voltage environments.
The Halogen bulb (6V-30W) has an average life span of up to 500 hours. The LED has an average life of
50,000 hours.
The Lx 500 comes equipped with a removable flip top N.A. 1.25 Abbe condenser with aspheric lens for
brighter illumination levels, and an iris diaphragm for better resolution and contrast control.

containing bacteria, clean any surfaces that came in contact with the
specimen to prevent infection.

SAFETY INFORMATION

Applicable to 6V-30W Halogen bulb (P/N EL-455)
2. Install microscope on a sturdy, level table or bench and avoid any restriction of air vents in the base of the unit.
Do not place microscope on a flexible surface, as this could result in blocking the air vents and cause overheating.
3. Always use the power cord provided. If the proper power cord is not used, product safety and performance cannot
be warranted.
4. When installing the microscope, route the power cord away from the microscope frame. Should the power cord
come in contact with the microscope base, the power cord could melt due to over exposure to heat.
5. Always ensure that the grounding terminal of the microscope and that of the wall outlet are properly connected. If
the unit is not grounded, LABOMED cannot warrant electrical safety.
6. Never allow metallic objects to penetrate the air vents of the microscope frame as this could result in user injury
or damage to the microscope.
7. After operation, be sure to disconnect power cord from connector socket of the microscope and/or from the wall
power outlet.
Symbol Explanation
This surface has a tendency to heat up and should not be touched unless system has
completely cooled down.
Before use, carefully read the instruction manual. Improper use could result in injury to
the user and/or damage to the equipment.
Warning against risk of electric shock
Main switch is ON
Main switch is OFF
Safety Symbols
The following symbols are found on the microscope. For optimal use, it is recommended that users understand these
symbols and always use the equipment as prescribed
Be sure to remove the specimen before moving the product.
In case the specimen is damaged through erroneous operation, it is
important to clean all surfaces that may have come in contact with
the specimen.

1 A microscope is a precision instrument with delicate glass
components. Please handle with care.
2. Do not use the microscope where it is subjected to direct sunlight,
high temperature, humidity, dust and vibrations. (For the operating
conditions, see chapter 13,”SPECIFICATIONS”)
3. The microscope is ventilated by natural convection. Be sure to leave
enough space (10 cm or more) around the body.
4. Arm handle is provided for carrying the microscope.
To prevent damage, do not hold the microscope by the stage or
observation tube.
Be sure to remove the specimen from the stage clip before transporting
the unit to avoid damage to the specimen slide.

1. Clean all glass components by wiping gently with cleaning cloth provided. To remove fingerprints or oil smudges,
wipe with cleaning cloth slightly moistened with a mixture of Petroleum (85%) and Isopropanol (15%)
Since solvents such as petroleum and isopropanol are highly flammable, they must be handled carefully. Be sure
to keep these chemicals away from open flames or potential sources of electrical sparks- for example, electrical
equipment that is being switched “ON” or “OFF”. Also remember to always use these chemicals only in a wellventilated room.
2. Do not attempt to use organinc solvents to clean the microscope components other than the glass components. To
clean non-glass components, use a lint-free, soft cloth slightly moistened with a diluted neutral detergent.
3. Do not disassemble any part of the microscope as this could result in
malfunction or mitigated performance.
4. When not using the microscope, ensure that the frame is fully cooled
before storing the unit or covering it with the dust cover (provided).
5. To clean the condenser, fully loosen the securing knobs and remove
the condenser then wipe the front lenses of the condenser with optical
cleaning solution (mixture suggested above) and lens tissue.
The condenser can be re-attached by replacing it in its seat, tightening
securing knobs, and raising the condenser bracket to the desired
position.
6. Be sure to observe your local rules/regulation for product disposal.

Caution
If the microscope is used in a manner not specified by this manual, the safety of the user may not be warranted. In
addition, the equipment may be damaged. Always use the equipments as outlined in this instruction manual.

• Spiral motion( )
1. The objectives have been adjusted for a tight fit to prevent any damage during transportation. To remove an objective,
rotate it counterclockwise while gripping it with a rubber sheet to avoid any slippage.
2. To clean the lens surfaces, remove dust using a soft cloth or compressed air (cans available at your local electronics
store). For removing finger marks or grease, a soft cleaning cloth or lens tissue lightly moistened with cleaning solution
(85% Petroleum ether and 15% Isopropanol) should be used. For cleaning the objective optics, use Methanol. Observe
sufficient caution in handling Methanol. Place the objectives and/or eyepieces on a dust-free surface.
3. Blow all loose dust particles away with compressed air or small dust blower.
4. Remove all water-soluble dirt with distilled water. If this is unsuccessful, repeat using a solution of diluted liquid
hand soap. Remove any remaining residue with a dry cotton swab.
5. To remove oil, use a solution of diluted liquid hand soap initially. If this does not produce a statisfactory result, repeat
using a solvent (optical cleaning solution 85% Petroleum ether and 15% Isopropanol)
6. Grease must always be removed using a solvent.
7. Cleaning is acheived by using a spiral motion from the center to the rim. Never wipe using zig zag movements as this
will only spread the dirt with larger optical surfaces (e.g tube lenses) the spiral motion starts initially at the rim before
moving to the middle and is then followed by a center to rim cleaning motion. Several spiral wipes are recommended.
We recommended pure, volatile petroleum ether or optical cleaning solution as explained above.
Wipe using a spiral motion . Do not use a zig zag motion!
Cleaning of painted surfaces:
Avoid the use of any organic solvent (e.g. thinner, xylene, ether, alcohol etc.) for cleaning of painted surfaces of the
instrument. Painted surfaces can be cleaned with a lightly moistened micro-fiber cloth. Loose dust and other dirt
particles can be removed using a soft bristle brush.
Optics Cleaning
• Zig Zag motion (X)
Your microscope has been engineered for a long and safe operational life with minimal maintenance required. In general,
routine maintenance consists of keeping the microscope's working parts lubricated and optics clean. Always cover the
microscope with a dust cover when not in use.
