AmScope B340 Series Siedentopf Binocular Compound Microscope - 40X-1000X Magnification, 3W LED, 3D Mechanical Stage, Achromatic Optics, Coaxial Focus, Lab Grade for Professionals & Students

The AmScope B340-LED is a professional-grade biological Siedentopf binocular compound microscope engineered for advanced educational and clinical applications. This heavy-duty instrument features a medium-sized profile that balances streamlined ergonomics with a spacious working area, ensuring long-term durability with its solid metal build and protective enamel coating. The Siedentopf binocular head allows for precise interpupillary distance adjustments without affecting focus, while the 30-degree incline and 360-degree rotatable design provide a comfortable viewing experience for multiple users in a laboratory or classroom setting. Equipped with four high-quality achromatic DIN objective lenses—4X, 10X, 40X, and 100X—the B340-LED provides magnification levels from 40X to 1000X, ideal for studying detailed cellular structures and microorganisms. The integrated 3D two-layer mechanical stage features low-position coaxial controls for smooth and precise specimen manipulation, complemented by a coaxial coarse and fine focusing system with tension control. For optimal illumination, the microscope utilizes a powerful 3W LED sub-stage lighting system that provides cool, daylight-balanced light. This light is further refined by an Abbe condenser with a 1.25 numerical aperture and an iris diaphragm, allowing for precise control over contrast and depth-of-field. Built to meet professional standards, the AmScope B340 series offers a reliable imaging solution for veterinarians, medical researchers, and science students.
