Wild M20-EB research microscope. From the Wild Catalog: "The Wild M20-EB microscope is designed on modular principles. Its controls are easily accessible and are confortable to use. The large, stable base incorporates the entire illuminator; the latter, which is designed on the Koehler illumination principle, comprises a powerful 6V/ 20W halogen lammp and a Triac-controlled light intensity regulator. A swing-in frosted filter ensures that the field of view is uniformly illuminated." This M20-EB has been fully serviced and is in tip-top condition with a very smooth lamp intensity response, 6-place nosepiece with Fluotar 6X, Plan Fluotar 10X, Fluotar 20X, Fluotar 40X, and Fluotar 100X oil immersion objectives. The eyepieces are Wild 10X-K and the condenser is a flip 1.254 n.a. If you have never used a Wild microscope you don't know what you are missing in terms of precise controls and excellent images! All optics are clean, aligned, no dust, no element separations or oil fouled lenses.   Thanks for looking!
