RX51 Research Medical Biological Microscope
The RX51 is a research and clinical biological microscope with a 10X eyepiece and a 40X objective, designed for routine laboratory work in medical, teaching and research environments.

Product Overview
The RX51 is a research and clinical biological microscope with a 10X eyepiece and a 40X objective, designed for routine laboratory work in medical, teaching and research environments. It features a 100mm working distance and a 1:10.5 zoom ratio, allowing for stable handling of slides and samples under the optics. The microscope supports both transmitted light and phase contrast illumination, and the body is built for long-term use in high-traffic lab settings.

Key Benefits
- 100mm working distance allows room for slide holders, pipettes and tools under the objective
- 1:10.5 zoom ratio covers 4.8mm to 0.46mm field of view without changing objectives
- Phase contrast illumination enhances contrast in transparent biological samples without staining
- 10X eyepiece and 40X objective provide 400X total magnification, suitable for cell and tissue analysis
- Robust construction supports continuous use in teaching and clinical labs
Application Scenarios
- Routine histology and cytology slide examination in clinical pathology labs
- Teaching cell structure and tissue morphology in university biology courses
- Microbial culture inspection in research and diagnostic laboratories
- Blood smear analysis with phase contrast for unstained samples
- Long-duration observation of live cell cultures under controlled lighting
Who It Is For
- Clinical laboratories performing routine diagnostic testing
- University and college teaching labs in biology and medical sciences
- Research labs conducting cell and tissue studies
- Veterinary and agricultural diagnostic labs
- Medical training institutions requiring durable, repeatable instruments
Problems It Solves
- Fixed magnification systems require multiple objectives to cover different sample types
- Short working distance limits access to slides during staining or handling
- Lack of phase contrast illumination reduces visibility of transparent samples
- Poor mechanical stability leads to image drift during long observations
- Inconsistent illumination causes variable contrast across the field of view

Customization Options
- Option to replace the 40X objective with 10X, 20X or 60X objectives
- Eyepieces available in 15X and 20X for higher magnification
- Condenser upgrade to 1.4NA oil immersion for higher resolution
- Addition of a 1.25NA condenser with iris diaphragm
- Mounting of a camera adapter for digital imaging
Comparison With Other Options
| RX51 without phase contrast | The RX51 with phase contrast improves visibility of unstained biological samples without requiring chemical staining, reducing preparation time and preserving sample integrity. |
|---|---|
| RX51 with 20X objective | The 40X objective provides higher magnification for detailed cell and tissue analysis, while the 20X objective offers a wider field for initial scanning. |
| Digital biological microscope | The RX51 maintains a traditional optical path with manual controls, which is more reliable for long-duration observations and avoids software dependency or screen lag. |
Use Guide
- Adjust the interpupillary distance to 55~75mm before focusing to ensure a single merged image
- Start with the coarse focus at the lowest magnification, then fine-tune with the fine knob
- Use phase contrast illumination for transparent samples like live cells or unstained tissue sections
- Adjust the condenser height and aperture to match the objective used for optimal contrast
- Clean optical surfaces with lens paper and appropriate cleaning solution after each use

View DetailsFrequently Asked Questions
What is the working distance under the 40X objective?
100mm. This allows space for slide holders, pipettes and tools during sample handling.
Can I use phase contrast with other objectives?
Yes. Phase contrast is compatible with the 10X, 20X and 40X objectives when the appropriate phase rings are installed.
Does the microscope require a separate power supply?
Yes. The 12V/20W halogen lamp requires a 12V DC power adapter, which is not included in the standard package.
What is the total magnification with a 15X eyepiece?
600X. The total magnification is calculated as eyepiece magnification multiplied by objective magnification.
Can I attach a camera to this microscope?
Yes. A camera adapter can be added to the eyepiece tube for digital imaging with a C-mount or USB camera.
Is the stage suitable for long-term use?
Yes. The stainless steel stage and hardened steel gears are designed for repeated use in high-traffic lab environments.
