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 user 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) with 
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, monocular head, eyepiece, eyepiece 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 with 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.
