3.4 Locate the nosepiece underneath the plain stage (where the objectives will go), and
remove the plastic dust plugs. Save these in the accessory box. Install the objectives.
Each objective is packed in an individual plastic container. Remove each objective
from its container, and save the containers in the accessory box. Install the objectives
in the following order: 4x, 10x, 20x and 40x.
3.5 Attach the attachable mechanical stage to the right side of the plain stage. Lock the
attachable mechanical stage on with two thumbscrews from underneath.
Note: If the specimen dish/container size is too large you may remove the attachable
mechanical stage.
3.6 Put the stage insert into position.
3.7 Unwrap the protective tissue from the oculars (eyepieces) and install one in each eye
tube.
3.8 The glass filters may be wrapped in protective tissue. To install the filter, simply
insert the filter into the filter holder and slide the filter holder into the open slot above
the condenser. To remove the filter, just pull gently toward you. Store the filter in a
clean bag when not in use.
3.9 Plug the power cord to the back of the MV130 microscope to finish the installation.
4. Using Your Denville Scientific MV130 Microscope
Note: If your microscope has been exposed to extremes of temperature, please allow time
for all the parts to come to room temperature before turning on the power. Excess cold
can fog the lenses and may cause the lamp to fail.
4.1 Once you have assembled all the parts, plug the power cord into the appropriate AC
outlet.
4.2 Turn the light on using the rocker switch on the right side of the base. Next, adjust the
light intensity by turning the brightness adjustment wheel located on the left side of
the base. Note: Rapid repeated changes in light intensity would dramatically shorten
the life of the quartz halogen lamp.
4.3 In order to speed your familiarity with controls, choose a specimen slide you are
familiar with, such as an old hematology slide or choose a petri dish with a culture
sample.
4.4 Move the slide or petri dish to the center of the stage, by turning the stage control
knobs, just below the stage on the right side. These knobs allow you to move the slide
or petri dish on the X-Y axis (forward / backward and left /right).
4.5 Open the aperture diaphragm on the condenser (controlled by the small black lever
above the condenser). Turn the nosepiece to bring the 4X objective into place.
