adjustment. If you find that the stage is not moving up far enough to get your specimen in
focus, try turning the locking knob slightly to allow the stage to travel farther.
Regulating brightness of the view:
There are several ways to adjust the amount of light
which is shed on a specimen, and the light will affect the observation. In most cases, a better
view is obtained by the use of a colored glass filter inserted below the iris diaphragm. Slide
the filter holder to the right to reveal an open ring. Insert the blue filter into this ring and
slide the filter holder back into position under the diaphragm. The iris diaphragm below the
stage can be opened (slide lever back to left) or closed (slide lever forward) to control the
amount of light directed through the condenser. The condenser assembly under the stage can
be shifted up or down by means of the control knob (left hand side under stage) to effectively
move the light beam closer to (up) or away from (down) the specimen under observation.
MRP-3000
is also equipped with a field diaphragm installed over the collector lens for
Kohler illumination. Open or close this diaphragm as desired by rotating the outer ring to
control the amount of light aimed at the condenser assembly.
Finally, the dimmer control allows the user to adjust the intensity of the halogen light. Vary
these different methods of regulating the light beam on the specimen to obtain the most
effective view for your microscope needs.
After using your
Premiere

microscope, turn the dimmer control to the lowest setting and
turn off the power to prolong the life of the halogen bulb. Lower the stage by rotating the
coarse adjustment knob. The instrument should be covered with a hood to keep dust off it or
dis-assembled and stored in its styrofoam case.
MAINTENANCE
Like other optical instruments, this microscope should be kept in a cool, shady and dry place,
free from dust, fumes and moisture. If not stored in its box, cover with a hood to protect
from dust.
If there is any dirt settled on the lens, wipe it off gently with some lens paper. If alcohol
is used, be careful not to let it penetrate through the lenses and dissolve the gumming.
Any dust settled on the lenses can be blown away with an air blower or wiped off with a
clean soft camel hair brush. In cleaning mechanical parts and applying non-corrosive
lubricant, take special care not to touch the optical elements, especially the objective
lenses.
APPLICATION
Premiere
®
Model
MRP-3000
Microscope is one of the most modern designed
instruments for clinical examination and teaching demonstrations in laboratories, colleges
and medical fields. It is also an ideal instrument for biological, bacteriological,
pathological and pharmaceutical research. These microscopes are equipped with
achromatic objectives, planoscope eyepieces, Abbe condenser, built-in variable light
source providing Kohler illumination and coarse and fine focus adjustment to give a nice
sharp image. The magnifying powers range from 40X to 1000X.
The binocular microscope offers the advantage of being able to observe the specimen
with both eyes at the same time, allowing more comfort for the user when compared to a
monocular microscope. The depth of field of the binocular microscope is longer and a
stereo image can be obtained when observing a specimen.
ASSEMBLY INSTRUCTIONS
1.
Remove microscope stand from box and styrofoam packing and place it on a stable
work table.
2.
Remove all plastic bags and covering (these can be discarded).
3.
Remove binocular head from the packing.
4.
Remove the plastic cap covering the neck of the microscope base. Fit the binocular
head into the neck of the microscope stand and tighten with the screw clamp as
necessary. The head is 360° rotatable and can be adjusted to any position desired.
5.
Remove the plastic eyepiece tube covers and insert eyepieces into each eyepiece tube.
6.
Attach power cord to the back of microscope and connect to power source.
Your
Premiere
®
microscope is now ready for use.
