Olympus CX21 Binocular Biological Microscope

The Olympus CX21 Biological Microscope is a binocular upright microscope designed for routine brightfield microscopy in medical laboratories, schools, universities, hospitals, and biological research environments. It provides reliable optical performance for examining stained and unstained specimens such as blood films, urine sediments, microorganisms, tissue sections, and other biological samples. The CX21 uses Olympus optical components with a mechanical stage, coaxial coarse and fine focusing controls, revolving objective nosepiece, condenser, and transmitted illumination system. It is a durable microscope widely used for routine clinical and educational microscopy. Important: Olympus/Evident now lists the CX21/CX21LED as discontinued, with the CX23 as its replacement.
