Introduction

Thank you for your purchase of a MRC microscope. MRC microscopes are precision instruments, subjected
to meticulous examination in order to reach you in perfect condition. Their design combines easy
management and optimum functioning with minimum maintenance.
The information contained in this manual is likely to go beyond what the average us

er needs to know to use

the microscope, however, it is provided

to answer any queries that may arise.

Your new microscope combines high performance features, with an excellent degree of optical resolution
and clarity of image. It incorporates a mechanical stage that provides a travel range of 70mm x 50mm in X
and Y directions with a graduation of up to 0.1 mm, thus permitting the perfect positioning of the specimen.
Also included are objectives located on a ball bearing nosepiece allowing movement in both directions; a
precision coarse and fine focusing system; a moveable Abbe condenser with a numerical aperture of 1.25
N.A. and a built-in 12V/ 20W halogen variable light source.

These instructions should be read carefully before operating the microscope. They will permit you to use
your

new

microscope to its fullest capabilities. Terminology used to describe components and controls can

be found in the diagram on page 2.

These instructions are based on the assembly and use of the B1-220 model (Binocular) w

i

th

additional notes applying specifically to other models in the series.

Unpacking

All components of the microscope have been carefully packed to make sure they reach you in perfect
condition. We recommend that you do not discard any packing containers in case you need to return the
microscope, store it for long periods of time; or should it become necessary to transport it to a technical
service for any repair, or maintenance procedure.

The box should contain the following components, depending on the model:

• B1-211 (Monocular): Stand, Power cable, monocul

ar head, eyepiece, eyepi

ece protector, four
objectives, condenser, sample holder mechanism, blue, green and yellow filter, fuse, dust cover, a
bottle of immersion oil and a 2mm hexagonal key.

• B1-220

(Binocular):

Stand, Power cable, binocular head, two eyepieces, two eyepiece protectors,
four objectives, condenser, sample holder mechanism, blue, green and yellow filter, fuse, dust cover,
a bottle of immersion oil and a 2mm hexagonal key.

• B1-223 (Trinocular): Stand, Power cable, trinocular head, two eyepieces, two eyepiece protectors,
four objectives, condenser, sample holder mechanism, blue, green and yellow filter,

fuse,

dust cover,

a bottle of immersion oil and a 2mm hexagonal key.

Remove, and handle the microscope and all its components with extreme care.
Avoid touching the lenses of the optical elements and keep clear of contact w

i

th dust, water or other
contaminating agents, as they could stain, or damage the lens surface and affect the quality of the
image.

A. Place the microscope in an upright position on a flat, stable and clean surface.
B. Unscrew the black plastic protectors from the revolving nosepiece (3).
C. Remove the rest of the components from the box.

Assembly

All the steps described for the assembly of the microscope must be undertaken with extreme care,
and without forcing the placement of the distinct parts and elements of the microscope.

A. Condenser (10): Turn the coarse

focus knob (19) until the stage (8)
reaches its highest position. Turn
the focussing knob on the
condenser (Fig.1) until the
condenser holder reaches its
lowest position. Unscrew the
knurled locking screw on the
condenser, and insert the
condenser in the mounting ring so
that the aperture of the diaphragm
(9) faces the front of the
microscope and so can be
adjusted easily. Once firmly
placed in the mounting ring, firmly
tighten the locking screw, and turn
the condenser focusing knob until
in its highest position.
