General safety instructions
Intended use: A non-medical device
This microscope is intended for general observation of cells and tissues, with transmitted/reected illumination and
with the specimen xed on a slide.
Dangers associated with the operation
• Improper use could result in injury, malfunction or damage to property. It must be ensured that the operator
informs every user of existing hazards
• Danger of electrocution. Disconnect the power to the entire lighting system before installing, adding or
changing any component
• Not to be used in corrosive or explosive environments
• Avoid direct exposure of eyes to the collimated light beam or direct light from the light guides or bers
• To avoid a hazard to children, account for all parts and keep all packing materials in a safe place
Photobiological safety LED, important safety instructions
• Avoid direct eye exposure to any LED light source while switched on
• Before looking through the eyepieces of the microscope, lower the intensity of the LED illumination
• Avoid long and high-intensity exposure to LED light because this may cause acute damage to the retina of the eye
Prevention of biological and infectious hazards
Infectious, bacterial or viral biohazard substances under observation may be a risk to the health of humans and other
living organisms. Special precautions should be taken during in vitro medical procedures:
• Biological hazards: Keep a logbook of all the biological substances or pathogenic microorganisms that were
under observation with the microscope and show it to everybody before they use the microscope or before
they do some maintenance work on the microscope! Agents can be bacterial, spores, enveloped or non-
enveloped virus particles, fungi or protozoa
• Contamination hazard:
• A sample that is properly enclosed with a cover glass never comes in direct contact with the microscope
parts. In that case prevention of contamination lies in the handling of the slides; as long as the slides
are decontaminated before use and are undamaged and treated normally, there is virtually zero risk of
contamination
• A sample that is mounted on a slide without cover glass, can come in contact with components of the
microscope and may be a hazard to humans and/or the environment. Therefore, check the microscope and
accessories on possible contaminations. Clean the microscope surfaces and its components as thoroughly
as possible. Should you identify a possible contamination, inform the local responsible person in your
organization
• Microscope operators could be contaminated from other activities and cross-contaminate components
of the microscope. Therefore, check the microscope and accessories on possible contaminations. Clean
the microscope surfaces and its components as thoroughly as possible. Should you identify a possible
contamination, inform the local responsible person in your organization. it is recommended to wear sterile
gloves when preparing the slides and handling the microscope in order to reduce contamination by the
operator
• Infection hazard: Direct contact with the focusing knobs, stage adjustments, stage and eyepieces/tubes of
the microscope can be a potential source of bacterial and/or viral infections. The risk can be limited by using
personal eyeshades or eyepieces. You can also use personal protections such as operation gloves and/or safety
goggles, which should be changed frequently to minimize the risk.
• Disinfectant hazards: Before cleaning or disinfecting, check if the room is adequately ventilated. If not, wear
respiratory protective gear. Exposure to chemicals and aerosols can harm human eyes, skin and respiratory
system. Do not inhale vapours. During disinfection, do not eat, drink or smoke. Used disinfectants must be
disposed of according to local or national regulations for health and safety.

Disinfection and decontamination:
• Exterior casing and mechanical surfaces must be wiped with a clean cloth, dampened with a disinfectant
• Soft plastic parts and rubber surfaces can be cleaned by gently wiping a clean cloth, dampened with a
disinfectant. Discoloration can occur if alcohol is used
• The front lens of eyepieces and objectives are sensitive to chemicals. We recommend not to use aggressive
disinfectants but to use lens paper or a soft ber-free tissue, damped in cleaning solution. Cotton swabs may
also be used. We recommend you use personal eyepieces without eyeshades in order to minimize risk
• Never immerse or dip the eyepiece or objective into a disinfectant liquid! This will damage the component
• Never use abrasive compounds or cleaners that may damage and scratch optical coatings
• Properly clean and disinfect all possible contaminated surfaces of the microscope or contaminated accessories
before storing for future use. Disinfection procedures must be eective and appropriate
• Leave the disinfectant on the surface for the required exposure time, as specied by the manufacturer. If the
disinfectant evaporates before the full exposure time, reapply disinfectant on the surface
• Against bacteria, use a 70% aqueous solution of isopropanol (isopropyl alcohol) and apply for at least 30
seconds. Against viruses, we recommend to refer to specic alcohol or non-alcohol based disinfection products
for laboratories
Before returning a microscope for repair or maintenance through a Cole-Parmer dealer, an RMA (return authorization
form) together with a decontamination statement must be lled in! This document must be shipped together with the
microscope at all times.

Preparing the microscope for use
Carefully remove the items from its packaging and place them on a at,
rm surface. Please do not expose the microscope to direct sun light, high
temperatures, damp, dust or acute shake. Make sure the table or surface is
at and horizontal
When moving the microscope, use the left hand to hold the transport
handle and hold the base of the microscope with the right hand
Hold the microscope at the top of the stand arm when it needs be
moved. Holding the microscope by its stage or focusing knob will
damage the microscope
Caution! If the bacterial solution or water splatters over the stage, objective
or head, please pull out the power cord immediately and dry the microscope
Assembling Steps
Mounting the objectives
1. Rotate the coarse focusing knob to lower the stage to its lowest position
2. Install the objectives into the objective nosepiece from the lowest magnication to the highest in a clockwise
direction from the rear side of the microscope. When using the microscope, start using the low magnication
objective (4x or 10x) to nd the specimen and focus, then continue with a higher magnication objective to
observe in more detail
Placing the eyepieces
The 360° rotatable heads are equipped with WF10x eyepiece(s) (H). Please remove the screw before taking out the
eyepiece to prevent damage
1. Remove the cover(s) of the eyepiece tube(s)
2. Insert the eyepiece(s) into the eyepiece tube(s)
3. Lock the eyepiece(s) with a hexagon screw

9
Locking the eyepieces
To lock the eyepieces in binocular models please nd the screw as indicated in picture (A). Please note that location
can be slightly rotated from model to model.
Connecting the power adapter
The MSU-100 Series supports a wide range of operating voltages: from 100 to 240 VAC Please use a grounded power
connection
1. Make sure the power switch is o before connecting
2. Insert the connector of power cord into the MSU-100 Series power socket, and make sure it connects well
3. Insert the other connector of the adapter into the mains socket, and make sure it connects well
Do not bend or twist the power cord, it will be damaged. Use the power cord that is supplied by Cole-Parmer. If it is
lost or damaged, choose one with the same specications
Replacement of the Power Cord
If the power cord requires replacement, ensure that it is suitably rated. If in doubt consult your local dealer or qualied
electrician
Operation
Setting up the illumination:
For optimal contrast and resolution one should follow the procedure below:
A. Place a specimen on the object stage and focus, using the 4x objective, with a fully opened iris diaphragm
B. Turn light intensity to lowest position, then look through the eyepiece(s) and turn up to the comfortable light
intensity level
C. Turn the condenser in the highest position
D. Close the iris diaphragm, until it is just visible on the edge of the eld of view
The microscope is properly set for use with the 4x objective. For each other magnication in bright eld use, this
procedure should be repeated to ensure the best balance between contrast and resolution

Caution:
The maximum light intensity when using the 4x and 10x can damage the eyes!
Place the specimen slide
Use the clamp of the mechanical stage and can be carefully moved into X- and Y- directions (M)
1. Push the arm of the specimen holder backwards
2. Release the arm slowly clamping the slide with the cover glass facing up
3. Rotating the X and Y-axis knob will move the specimen to the center for alignment with the center of the
objective
Focusing and slide protection
1. Select the 4x objective and make sure that it is placed correctly in the optical path
2. Rotate the coarse adjustment knob to top, observe the right eyepiece with your right eye. Rotate the coarse
focusing knob until the image appears
3. Rotate the ne focusing knob to sharpen the image
4. When you perform focusing with a S100x objective, you need to lock the slide protection screw (D). The slide
protection screw protects the slide by limiting the travel range of the mechanical stage. This way the objectives
will not touch or break your slides. In case a standard version is purchased, including a S100x objective, this is
pre-set at the factory
Eyepieces
A binocular tube is less tiring for the eyes compared to a monocular tube. In order to obtain a smooth “compound”
image, we recommend you to go through the steps below:
1. The interpupillary distance
The correct interpupillary distance is reached when one round image is seen in the eld of view (see image below).
This distance can be set by either moving the tubes towards each other or moving them away from each other. This
distance is dierent for each observer and thus should be set individually. When more users are working with the
microscope it is recommended to remember your interpupillary distance for a quick set-up during new microscopy
sessions

2. The correct eye point
The eye point is the distance from the eyepiece to the user’s
pupil. To obtain the correct eye point, move the eyes towards the
eyepieces until a sharp image is reached at a full eld of view
3. Adjusting the diopter
This chapter is only applicable for bino and trino’s
• Set diopter adjustment ring to zero (I)
• Close the left eye and focus the right tube by adjusting the
coarse- and ne adjustment knobs (O)
• Close the right eye and focus the left tube with the diopter
adjustment ring
This procedure should be followed by each individual user.
When more users are working on the same microscope it is
recommended to remember your own diopter setting for a quick
set-up during new microscopy sessions
Abbe condenser
Beneath the object stage an Abbe condenser N.A. 1.25 is mounted. The condenser can be adjusted in height by
moving the lever beneath the (mechanical) stage (N). By adjusting the condenser you can focus the light on the
specimen for an optimized contrast. The condenser is factory pre-centered. If needed, the following procedure can be
followed to center the condenser
A. Move the condenser to its highest position
B. Select the 4x objective and place it into the light path and focus the specimen
C. Slide the lever to adjust the diaphragm to the smallest position
D. Adjust the condenser height to the point where the image is the sharpest
E. Adjust the center adjustment screws using an allen key and move the image of the condenser ring to the center
of the eld of view
F. Open the diaphragm gradually
G. The condenser is centered correctly if
the image remains in the center when
you open the diaphragm

Use of the S100x oil-immersion objective
Some Cole-Parmer MSU-100 Series microscopes are equipped with an S100x N.A. 1.25 oil immersion objective. Please
follow the instructions below on how to use this objective:
1. Remove the dust protection cap from the revolving nosepiece to mount the S100x objective (the objective can
be premounted)
2. Focus the image with the S40x objective
3. Turn the revolving nosepiece so the S100x objective almost reaches the click-stop
4. Put a small drop of immersion oil on the center of the slide
5. Now turn the S100x objective so that you feel the click stop
6. The front lens is in contact with the immersion oil
7. Look through the eyepiece and focus the image with the ne adjustment knobs
8. The distance between the lens of the objective and the slide is very small!
9. In case there are small bubbles visible, turn the S100x objective a couple of times from left to right so that the
front of the objective moves in the oil and the bubbles will disappear
10. After using the S100x objective, loosen the slide protection handle and turn the table with the course
adjustment knobs downwards until the front lens doesn’t touch the oil any longer. Clean the front lens of the
S100x objective
11. Always clean the front lens of the S100x objective with a piece of lens paper that is moistened with a drop of
isopropanol.
12. Clean the slide after use as well
Caution
• Never put a drop of xylol or alcohol directly on the lens of the objective. It could enter the objective and dissolve
the glue that holds the lenses!
• Avoid oil contact with any of the other objectives!
Safety device
To prevent damage to the objective lens, or breaking the slide, all types are equipped with a pre-xed safety device.
It is recommended to use slides of 1.0 – 1.2 mm thickness in combination with cover glasses of 0.13 mm or 0.17 mm
thickness
Illumination
The LED illumination of the MSU-100 Series is equipped with rechargeable batteries. The length of use after charging is
about 48 hours. The full charging time is about 10 hours. At rst use the batteries will have to be fully charged. Connect
the external power supply unit to the power inlet socket. For all models with batteries it is highly recommended to use
the microscope with power supply disconnected to keep the batteries in good working condition and recharge after
batteries run empty
The illumination has the following specications:
• 1W NeoLED : 1W, 300mA equipped with Fresnel lens
• External Charger : Primary 100-240 VAC, 50/60 Hz, 0.3 A
• Batteries : 3 NiMh, AA type, 1.2 Volt 1600 - 2000 mA.

13
Maintenance and cleaning
Always place the dust cover over your MSU-100 Series microscope after use. Always keep the eyepiece and objectives
mounted on the microscope to avoid dust entering the instrument
Cleaning the optics
When the lens of the eyepiece or the front lens of the S40x, S60x or S100x objective is dirty, they can be cleaned by
wiping a piece of lens paper over the surface (circular movements). When this does not help put a drop of alcohol on
the lens paper and wipe it. Never put xylol or alcohol directly on the lens!
It is not necessary – and not recommended – to clean the lens surfaces at the inner side of the objectives. Sometimes
dust can be removed with high pressured air. There will never be dust in the objectives if the objectives are not
removed from the revolving nosepiece
Caution
Cleaning cloths containing plastic bers can damage the coating of the lenses!
Maintenance of the stand
Dust can be removed with a brush. In case the stand or table is really dirty then you can clean the surface with a non-
aggressive cleaning product. Moving parts, like mechanical stage, contain ball bearings that are not dust sensitive.
With a drop of sewing-machine oil you can lubricate the bearing.
Changing the batteries
Caution: Always remove the power cable from the mains supply!
• Open the small lid at of the bottom cover of the microscope by unscrewing the chrome screw
• Open battery compartment with small Philips screwdriver
• (Re)place the batteries and put the lid back into its place
