performing properly and compensate for normal wear. Anticipating this need by
establishing a schedule of regular preventive maintenance will help to assure
long life and sustain optimum performance by your instrument.

Such a program of planned preventive maintenance, involving a thorough
cleaning, checking and adjustment of mechanisms is recommended. Qualified
personnel with the proper training should perform this work.

RESEARCH MICROSCOPE

APPLICATION

Research Microscope is a professional laboratory instrument for the modern
biology and medical sciences. Its modular design allows for a full range of
accessories.

SPECIFICATIONS

•10x Widefield Eyepiece w/ pointer

Focus

Focus the T-3300 microscope by observing with the 10x objective and 10x
eyepiece on the side without diopter ring. Rotate the coarse adjustment knob to
lift the stage until the image of the specimen can be seen roughly, then rotate
the fine adjustment knob. A sharp image can then be obtained. (Loosen the
auto focus stop knob for free stage motion when it is necessary). Prevent the
objective lens from touching the specimen. (Tighten the auto focus stop to limit
the stage moving past a certain point). Observe the image with the other eye­piece and adjust the diopter ring until the sharp image is obtained. Change the
magnification of the objective as required by turning the nosepiece.

MICROSCOPE PREPARATION

Set the viewing head onto the microscope arm and lock the

head by tightening the lock screw. Position the condenser with the han-

dle of aperture diaphragm conveniently accessible. Swing the filter holder out­ward and insert the filter when it is necessary.

OPERATION

Built-In Illuminator

Plug the microscope power cord into a suitable grounded electrical
outlet. Move the illuminator switch to the “ON” position. To obtain the desired
illumination, adjust the light control dial. Put the specimen to be observed onto
the stage of the microscope and clamp it firmly with the stage fingers. Bring the
spot of specimen to be observed into the center of stage hole by rotating stage
X – Y movement knobs.

Eyepiece

Set the interpupillary distance by moving the eyepiece tubes together or apart
until the full field of view is visible by two eyes at the same time.

Depending upon specimen density and objective magnification, the light level
should be adjusted. If the light is excessively yellow, place the blue filter in the
condenser filter holder. To eliminate light irregularity when using low-power
objectives such as 4x and 10x, raise or lower the condenser using the condens­er adjustment knob. Close down the condenser iris diaphragm to the smallest
size for observing a specimen with low contrast.

BULB REPLACEMENT

Before replacement, unplug the instrument. Open the lamp window in the bot­tom plate by pulling the window knob. After the lamp has cooled, carefully
remove it from its socket and replace with a new lamp. Be careful not to touch
the new lamp with your fingers. Never operate the microscope illuminator unless
the lamp window is securely in place.

CARE AND MAINTENANCE

Our product is a precision instrument. Routine maintenance on your part is
limited to keeping the microscope clean. Never leave the microscope with any
of the objectives or eyepieces removed. Always protect the microscope with the
dust cover when not in use.

Cleaning the Microscope

Accumulated dirt on the metal surface should be cleaned with a damp cloth. If
this is inadequate, a mild soap solution should be used. The outer surfaces of
the optics should be inspected from time to time for dirt and dust. An air stream
from a rubber air bulb removes dust best. Remove more persistent dirt with a
soft cloth or cotton swab dampened in alcohol or a mild solution of Windex and
water. A small amount of absorbent cotton wound on the end of a tapered stick
makes a handy tool for cleaning recessed optical surfaces. Avoid excessive use
of solvents as this may cause problems with cemented optics or the flowing sol­vent may pick up grease from the mounts, making cleaning more difficult.

Clean immersion objectives immediately after use by removing the oil with
lens tissue or a clean soft cloth. Occasionally the underside of the mechanical
stage fingers may become coated with immersion oil and require cleaning.
