The B-292 Binocular Brightfield Microscope is a professional upright laboratory microscope designed for educational, clinical, research, and routine laboratory applications. Built with a durable aluminum die-cast body and ergonomic binocular observation system, the microscope delivers excellent optical performance, user comfort, and long-term reliability.
Equipped with premium N-PLAN objectives, the B-292 provides sharp, high-contrast images with magnification ranging from 40x to 1000x. The anti-fungus treated optical system ensures dependable performance even in humid laboratory environments.
The microscope features a binocular Siedentopf viewing head inclined at 30° and fully rotatable 360° for comfortable observation during extended laboratory sessions. Its quadruple reversed nosepiece mounted on ball bearings allows smooth and precise objective rotation.
The rackless double-layer mechanical stage provides accurate specimen positioning with smooth X-Y movement controls, while the coaxial coarse and fine focusing system ensures precise focusing adjustments.
The advanced X-LED3 illumination system delivers bright white light with low power consumption and a lifetime exceeding 65,000 hours. Optional darkfield and polarized light accessories expand the microscope’s versatility for advanced laboratory applications.
The B-292 is ideal for laboratories, educational institutes, pathology labs, hospitals, universities, and research facilities requiring reliable brightfield microscopy.
