Upright Microscope BX43
High Performance in a Cost-Effective System
The modular BX43 microscope enables you to choose between cost-efficient and advanced configurations, depending on your needs. Modular components, such as ergonomic observation tubes and stages, make it simple to customize your microscope to your application.


High Color Rendering White LED
With luminosity equivalent to a 30 W halogen lamp, this long-lasting LED provides a consistent color temperature at any brightness level with an estimated 20,000-hour lifetime.
Maintain Brightness when Changing Magnifications
The light intensity manager eliminates the step of having to adjust the brightness when changing magnification, helping you complete your work faster and with less eye strain.
Customizable for Different Observation Styles
Modular units enable you to customize your microscope for brightfield, polarization, phase contrast, and fluorescence. Modular options include:
- Condensers
- Observation Tubes
- Nosepieces
- Stages
- Objectives
- Intermediate optics
Stay Comfortable with the Ergonomic Tube
The tube moves up and down, tilts, and extends forward and back. With this one component, users of nearly any height can adjust the scope so that they’re comfortable.

LED Made for Clinical Research Applications
The LED’s color rendering index is similar to a halogen bulb with a daylight filter. Stains look the same as if you were using a traditional daylight filtered halogen lamp and similar colors can be differentiated. Unlike a halogen light source, the LED has an estimated 20,000-hour lifetime.
Condensers for Clinical Research Brightfield Applications
For clinical research where brightfield observation of stained specimens, such as HE-stained tissue, is common, we offer condensers with white tops, enabling you to easily position slides by eye. Condensers for darkfield, phase contrast, and low-magnification observations are available.

Low-magnification condenser (2X to 100X magnification)

Abbe condenser (4X to 100X magnification)

Swing-out condenser (1.25X to 100X magnification)

8-position, universal condenser enables brightfield, phase contrast, darkfield, polarized light, and DIC observations
