Accu-Scope EXI-310 Description
The Accu-Scope EXI-310 is a professional inverted trinocular microscope designed for advanced cell culture, live-cell imaging, and routine laboratory research. Its robust construction, featuring a cast aluminum stand, ensures stability during precise microscopy work, while the 45° inclined Siedentopf trinocular head allows comfortable viewing for extended periods. The microscope supports a wide range of observation techniques, including brightfield, phase contrast, and optional epi-fluorescence, making it highly versatile for biological and clinical applications.
Optically, the EXI-310 utilizes an infinity-corrected system with high-quality objectives, including Plan Achromat, Plan Phase, and optional Plan Fluor lenses, providing excellent resolution, flatness, and color fidelity across the field of view. The side-facing quintuple nosepiece accommodates multiple objectives for rapid switching, while the LED illumination system delivers bright, uniform light with adjustable intensity and long bulb life. For phase contrast models, pre-centered phase annuli enable precise imaging of transparent specimens without additional adjustments, and fluorescence-capable models can incorporate filter cubes for multichannel imaging.
The microscope also integrates user-friendly features for modern lab workflows. Coaxial coarse and fine focus knobs with tension adjustment allow precise focusing, and the fixed stage or optional mechanical stage facilitates sample manipulation. A dedicated trinocular camera port supports digital imaging, enabling documentation, analysis, and teaching applications. With accessories such as filters, dust cover, and a five-year limited warranty, the EXI-310 combines durability, optical excellence, and flexibility, making it a powerful tool for research, education, and clinical laboratories alike.
