{"product_id":"microscopio-biologico-magus-bio-250bl","title":"MAGUS Bio 250BL Biological Microscope","description":"\u003cp\u003eThe MAGUS Bio 250BL microscope can be used for lab work, scientific research, and student training. It is designed for observing thin sections and smears of biological samples in transmitted light. The primary observation method is the brightfield technique, but it is also possible to use darkfield, polarization, and phase contrast techniques (with additional accessories).\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/es.magusmicro.com\/uso-profesional\"\u003eMicroscope in use »\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOptics\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe microscope comes with 4 infinity-corrected plan achromatic objectives. They produce well-detailed images with minimal distortion. The objectives are mounted in the revolving nosepiece, which is designed to hold 5 objectives at once, leaving one position free. This allows an additional objective to be used to achieve additional magnification power within the magnification range. The revolving nosepiece is inward-facing.\u003c\/p\u003e\u003cp\u003eThe position of the microscope head is comfortable for long work. The height of the eyepieces can be adjusted by rotating the eyepiece tubes 360°. The left tube has a diopter adjustment ring and also supports mounting a digital camera (not included).\u003c\/p\u003e\u003cp\u003eThe magnification range of the microscope is 40x to 1000x. The upper limit of the range can be increased by adding additional eyepieces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIllumination\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLED lamps allow the brightness level to be changed without changing the color temperature. The LED bulb has a lifespan of 50,000 hours and a power of 3 W. The illumination system requires a 220V power supply to operate.\u003c\/p\u003e\u003cp\u003eThe illumination system also includes an Abbe condenser with an aperture diaphragm and a slot for slider plates. The slot allows for the installation of a darkfield slider or a phase slider. This way, the user can more quickly switch between different observation techniques. The microscope is also equipped with a field diaphragm. This allows the Köhler illumination system to be used.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eStage and focusing mechanism\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe main mechanical feature of the microscope is its specimen stage, which lacks a positioning rack. It is easy to operate, and its mechanism requires less space. The observed sample can be moved using a removable mechanical micrometer.\u003c\/p\u003e\u003cp\u003eThe focus knobs are located at the bottom, where they are more comfortable to use: there is no need to keep your hands in the air, allowing you to adopt a relaxed posture while working. The coarse focusing mechanism has a lock knob and tension adjustment. There is a fine focus knob. The knobs are arranged coaxially on both sides of the microscope body.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAccessories\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIf the microscope's power is insufficient, it can be increased with additional accessories.
