Lx 400 Research Microscopy User Manual To ensure proper use of this instrument as well as to avoid injury while operating Part No: 9126000-795 Instrument, understanding this manual completely before use is highly recommended. Issue 1.5 Printed on April,2019...
Lx 400 INTRODUCTION The Lx 400 is a research microscope reflecting a modern design as well as the latest in optical and mechani- cal advancements. Designed for professionals as well as clinicians, this microscope offers many features and functions for a diverse of applications. Here are a few points highlighting the benefits of the Lx400: -Extra clarity and contrast is provided through a 360°...
Do not place microscope on a flexible surface, as this could result in blocking the air vents and cause overheating. 4. Always use the power cord provided by LABOMED. If the proper power cord is not used, product safety performance cannot be warranted.

Lx 400 CARE & MAINTENANCE Your microscope had been engineered for a long and safe operational life with the least amount of main- tenance required. In general, routine maintenance is limited to keeping the microscope working parts lubricated and optics clean. Always cover the microscope with the provided dust cover when not in use.
Lx 400 STANDARD COMPONENTS After removing your microscope from its packaging, make sure that all of the following contents are present. “Please note that the contents of your microscope may vary as the optional configuration, contrasting method or viewing body opted for may not be of the standard configuration highlighted here”.

Lx 400 OPTIONAL EYEPIECES 10X eyepieces are provided. To replace: 1. Pull out the 10x eyepieces out from the observation heads Ocular tube. 2. Insert desired eyepieces in empty ocular tube. Fig. 5 PHASE TURRET 1. Remove the condenser from its position by loosening the thumb screw (1) on right side of the condenser bracket as shown in figure 6.

Lx 400 Rotate anti clockwise 4. Open the illumination assembly as in (figure 9), by rotating T Ring the T Ring. Replace the lens B with frosted lens provided with the Lens B Koehler kit. Lens Spacer Secure the lens assembly back.
Lx 400 INITIAL SETUP OBJECTIVES Objectives are factory set. Objectives are par-centered and parfo- calised during assembly. All objectives have been secured for a tight fit to prevent them from coming loose during transit. To remove an objective, rotate it counterclockwise while holding it with a rubber grip to avoid any slippage.
Always use the designated bulb. Using a bulb other than those specified by LABOMED may lead to a fore hazard or and low illumination. Fingerprints or stains on the lamp bulb reduce its life.

3. Detach connector of connecting wires (shown as 4) 4. Remove two screws (shown as 6) provided on battery clamp with Cross head screw driver. 5. Replace existing Battery with new battery from LABOMED (Refer part no. below) 6. Reverse steps 5 to 1, to complete the process.
Lx 400 SUMMARY OF BRIGHT FIELD OBSERVATION PROCEDURE Flip the main switch to “ON” Place the specimen on the stage. Fuse Holder Main switch Engage the required filters if not pre-installed. Engage the 10X objective in the light path. Bring the specimen in light path using X-Y Motion of mechanical stage.
Lx 400 DETAILED OBSERVATION PROCEDURE TURNING THE LAMP ON 1. Flip the main switch to “I” (ON) as shown in figure 20. Fig. 20 2. Rotating the light intensity adjustment knob (Fig. 21) in the direction of the arrow increases brightness and rotating knob in the opposite direction decreases brightness.

Lx 400 ADJUSTING THE INERPUPILLARY DISTANCE (IPD) The inter-pupillary distance adjustment consists of regulating the two eyepieces to align with both eyes’ pupils so that you can observe a single microscope image through two eyepieces in stereo vision. This greatly helps to reduce fatigue and discomfort during observation.

Lx 400 CENTERING THE CONDENSER The condenser is fixed and cannot d-center. In case of any error, remove the condenser by loosening thumb screw and re-install the same. For models with Koehler illumination: The Koehler mount has the floating diaphragm mount (fig.

USING THE 100X IMMERSION OBJECTIVE The designated immersion oil should be in contact with the cover lens of the 100X immersion objective. If not, the specimen will appear distorted and dull. It is recommended that LABOMED immersion oil is always used. Immersion Process 1.
Lx 400 CLEANING AND SERVICING 12.1 CLEANING OF OPTICAL SURFACES: The Max lite multi-layer coating of the optical components (e.g. eyepieces objective lenses) ensured optimum images quality. Image quality is impaired by even slight contamination. To protect the internal optics from dust, the system should never be left without the objective lens, binocular tube and eyepieces.
