General safety instructions

Intended use: a non-medical device

This microscope is intended for general observation of cells and tissues, with transmitted/reflected illumination and with the specimen fixed 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 fibres
• 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 non­enveloped 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 organisation
• Microscope operators could be contaminated by 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 organisation. 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 protection 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 fibre-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 effective and appropriate
• Leave the disinfectant on the surface for the required exposure time, as specified by the manufacturer. If the disinfectant evaporates before the full exposure time, reapply disinfectant on the surface
• For disinfection 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 specific alcohol or non-alcohol based disinfection products for laboratories

Before returning a microscope for repair or maintenance through a Euromex dealer, an RMA (return authorization form) together with a decontamination statement must be filled in! This document – available from Euromex for any reseller- must be shipped together with the microscope at all time

2. (Fig. 12) Turn the button (1) clockwise to increase light, and turn anticlockwise to decrease it
   • Use the bulb in low voltage to increase it’s life span

Place the sample

1. (Fig. 13) Place the sample in the center of the stage (1)
2. (Fig. 14, next page) In order to clip board of any type tightly, please use holder (3) and attachable mechanical stage (2), use the sample clip (4) to clip the holder (3),turn horizontally shift ring(S) and vertically shift ring (6) to shift the specimen to proper place. (Working distance range: 120 mm x 80 mm)

Shift the optical way
(Fig. 15) Using the lever, one can move the internal beam splitter to two different positions

• In one position, 20% of the light path goes through the eyepieces and 80% of the light path goes to the photo port
• In the second position, 100% of the light goes through the eyepieces

Focus

1. Place the sample on the stage, move the SX objective into the light path. The surface of the placed sample should be positioned perpendicular to the objective. To prevent the sample from moving plasticine may be used
2. Adjust the diopter adjustment ring to “0”, (see 3-6 Adjusting the diopter)

Adjusting the focusing tension
(Fig. 16) If focusing is too tight or too easy (the stage declines by itself) this problem can be solved by adjusting the tension adjustment ring; when turning the ring in the direction of the arrow the friction increases, in the opposite direction the friction decreases

Adjusting the diopter

1. Adjust the diopter adjustment ring to “0”
2. Focus with both eyes on the specimen
3. Use left eye (right eye closed) and focus with (left) diopter adjustment
4. Take your eyes off the sample and turn back the diopter a few divisions
5. Reset your eyes by looking in the distance for a few seconds
6. Refocus with the left diopter, again using your left eye (right eye is closed)
7. Follow the same procedure for the right diopter adjustment
8. Remember your settings for future use

Adjusting the interpupillary distance

1. (Fig. 17) Use both eyes to observe, hold the base of the prism and rotate it around the axis until there is only one field of view
2. The”.” (1) on the side marks the position. The number is the interpupillary distance (2).
   Range : 50-?Smm. Remembering your interpupillary distance may speed up your personal setup when you use the microscope next time

Using the eye-cap

1. (Fig. 18) If you wear glasses, turn over the eye-cap (1). It can prevent your glasses touching the eyepiece, thus avoiding damaging your glasses and the eyepieces
2. If you do not wear glasses, open the eye-cap (2). It can prevent stray light disturbing the observation

Using the ground glass slider
(Fig. 19) When putting the ground glass slider (1) in the left position the filament can be centered. When putting the slider in the right position the diffuse light causes the illumination to be uniform

Using the color filter
(Fig. 20) A variety of filters can be inserted in slot. For example a daylight or frosted filter

Adjusting the field diaphragm
By limiting the diameter of the beam entering the condenser, the field diaphragm can prevent stray light and avoid unnecessary optical aberrations. When the image of the field diaphragm is just outside the edge of the field of view, the best image can be obtained

1. (Fig. 21, 1) Pull rod to close the iris of the the field diaphragm
2. The image of the field diaphragm can be seen in the view of field through the eyepiece
3. Adjust the right and the left centering screws (2) on the field diaphragm until the image is centered
4. Open the field diaphragm gently (1). If the image in the diaphragm field is visible at the center of the view field, it means that the field diaphragm is properly centered (Fig. 22)
5. Enlarge the field diaphragm gently until just outside the view field

Adjusting the aperture diaphragm

• The aperture diaphragm influences the numerical aperture of the illumination. If the N.A. of the illumination matches with the N.A. of the objective, you can obtain better resolution and contrast, and increase the depth of field
• (Fig. 23) Adjusting the aperture diaphragm is done by using the lever(l)
• Adjust the size of the aperture diaphragm to your own preference

Centering the filament
(Fig. 24 and Fig. 25) Adjust the filament to the center of the field of view in order to get a uniform illumination

1. Pull the ground glass slider (1) out of the optical way until you hear a “click”
2. Push in the field diaphragm lever (4) and the aperture diaphragm lever (5)
3. Put a white piece of paper on the metal stage
4. Rotate the nose piece to bring an empty hole into the light path. If there is a dust cap on the hole, remove it
5. Adjust the halogen bulb horizontal adjustment screw (2) and vertical adjustment screw (3). Find the filament image on the paper. Adjust the focus lock handle (6) to get a clear filament image. Then center it in the view field
6. Push the ground glass slider back into place. Then put a sample on the metal stage, adjust the focusing knob in order to get a clear image
7. Get the best view by adjusting the focus lock handle (6) while looking through the eyepieces, then lock it
8. Adjust the field diaphragm (4) and the aperture (5) to complete the procedure

Using the simple polarizing kit
(Fig. 26) The simple polarizing kit includes the polarizer (1) and the 360° rotating analyzer (2)

1. Mount the polarizer and the 360° rotating analyzer (2) according to 6.8 and 6.9 (When using the polarizer, remove the color filter)
2. Dialling the filter in the 360° rotating analyzer can change the state of the polarized light

Replacing the fuse
(Fig. 27) Before replacing the fuse, please make sure the power switch is at “O” (Off) and remove cable from the socket. Use a screwdriver to take outthe fuse (1) from the fuse holder (2) and replace with a new one Fuse specifications: 250V, 3.1 SA

Mounting and using the c-mount adapters

1. (Fig. 28) Loosen the lock-screw (1) on the photo tube and take off the cap (2)
2. Take off the caps of c-mount adapter (3), place the adapter on the photo tube and lock by screw (1)
3. Fix camera to c -mount (5)
4. Adjust the image while looking through the eyepieces, then pull the light path shifting switch (7) to the left. Now you can obverse the image produced by the camera. If it is not clear, you can adjust the length of the c-mount adapter (6) till the image is in focus

Maintenance

1. Clean the lenses gently with a soft lens tissue. Carefully wipe off oil or fingerprints on the lens surfaces with tissue moistened with a 30/70 mixture of ethanol and aether or better isopropanol (as pure as possible)
   Note: Ethanol and aether are both flammable. Please keep them away from fire or hot sources, especially when turning on or off the power switch
