XD Series Inverted Biological Microscope for Research and Clinical
The XD Series Inverted Biological Microscope is designed for research and clinical applications requiring stable, high-contrast imaging of live or fixed cell cultures, tissue sections, and microorganisms on

Product Overview
The XD Series Inverted Biological Microscope is designed for research and clinical applications requiring stable, high-contrast imaging of live or fixed cell cultures, tissue sections, and microorganisms on glass slides. It features a fixed 4X objective and a 10X eyepiece, providing a total magnification of 40X. The microscope uses a transmitted light illumination system with a 6V 20W halogen lamp and a built-in condenser with adjustable aperture diaphragm, allowing precise control of light intensity and contrast. The stage is a fixed mechanical stage with a 110mm x 110mm platform and a 30mm height clearance, suitable for standard 25mm x 75mm slides and coverslips. The stand is constructed from cast iron with a powder-coated finish for stability and corrosion resistance.

Key Benefits
- Fixed 4X objective and 10X eyepiece provide 40X total magnification for routine cell and tissue observation
- Transmitted light illumination with 6V 20W halogen lamp and adjustable condenser diaphragm for contrast control
- Fixed mechanical stage with 110mm x 110mm platform and 30mm stage height clearance for slide handling
- Cast iron stand with powder-coated finish ensures vibration resistance and long-term stability
- No moving parts in the optical path reduce alignment drift during extended observation sessions
Application Scenarios
- Routine observation of live cell cultures in a clinical or research laboratory
- Microscopic examination of tissue sections and stained slides in a pathology setting
- Teaching undergraduate biology labs where consistent magnification and stable focus are required
- Quality control of cell growth in biotech or pharmaceutical research environments
- Documentation of microorganism morphology using a connected camera or smartphone adapter
Who It Is For
- Clinical laboratories performing routine cell and tissue analysis
- University and college biology teaching labs for undergraduate practicals
- Research labs conducting cell culture and microbiology studies
- Biotech and pharmaceutical quality control departments
- Veterinary and agricultural research facilities analyzing biological samples
Problems It Solves
- A microscope with no fixed objective forces users to swap lenses during observation, increasing setup time and risk of misalignment
- Low stage height limits the use of thick slides or coverslips, restricting sample compatibility
- Unstable stands introduce vibration during focus adjustment, especially at higher magnifications
- Lack of adjustable illumination control leads to overexposure or underexposure in transmitted light applications
- Moving stage mechanisms increase wear and require frequent recalibration
Technical Features
- Inverted optical design with fixed 4X objective and 10X eyepiece for transmitted light observation
- Transmitted light illumination with 6V 20W halogen lamp and built-in condenser with adjustable aperture diaphragm
- Fixed mechanical stage with 110mm x 110mm platform and 30mm stage height clearance
- Cast iron stand with powder-coated finish for rigidity and corrosion resistance
- No moving optical components in the body to maintain alignment over time

Customization Options
- Option to replace the 4X objective with 10X, 20X, or 40X fixed objectives (available as separate SKUs)
- Add a 1.5X or 2X Barlow lens to increase magnification to 60X or 80X
- Upgrade to a 12V 30W halogen lamp for higher brightness
- Replace the fixed mechanical stage with a motorized stage (not available in this model)
- Add a camera adapter for USB or HDMI output (requires separate camera purchase)
Comparison With Other Options
| Standard upright biological microscope | The inverted design allows direct observation of samples in culture dishes or flasks without removing them from the incubator, reducing contamination risk and handling time. |
|---|---|
| Microscope with moving stage | The fixed stage eliminates wear and misalignment from repeated movement, improving long-term stability and reducing maintenance. |
| Microscope with no adjustable condenser | The built-in condenser with adjustable diaphragm allows better control of contrast and resolution, especially at higher magnifications. |
Use Guide
- Ensure the lamp is fully warmed before starting observation to achieve stable brightness
- Adjust the aperture diaphragm to match the objective used for optimal contrast and resolution
- Place the slide on the stage with the coverslip facing up; the 30mm clearance allows for thick samples
- Use the coarse focus first, then fine focus to avoid damaging the objective or slide
- Do not operate the lamp continuously for more than 2 hours without a cooling break to extend bulb life

Frequently Asked Questions
What is the total magnification of the standard configuration?
40X, using the fixed 4X objective and 10X eyepiece.
Can I use this microscope for observing samples in culture dishes?
Yes. The 30mm stage height clearance allows for standard 35mm or 60mm culture dishes to be placed on the stage.
Is the lamp replaceable?
Yes. The 6V 20W halogen lamp is accessible from the base and can be replaced with a compatible bulb.
Can I upgrade the objective to 10X or 20X?
Yes. The 4X objective is fixed in the standard model, but 10X, 20X, and 40X objectives are available as separate SKUs for replacement.
Does the microscope have a built-in condenser?
Yes. The condenser is built into the base and includes an adjustable aperture diaphragm.
What is the stage height clearance?
30mm, which allows for thick slides, coverslips, and small culture dishes to be observed without interference.
