Digital inverted microscope MAGUS Bio VD350

The MAGUS Bio VD350 microscope is designed for the study of liquid sediments, cell colonies, living cells, tissue cultures and other stained and unstained objects in laboratory glassware. The inverted design of the microscope involves the use of Petri dishes, multi-well plates, vials, roller bottles and flasks up to 55 mm high with a bottom thickness of 1.2 mm. The microscope uses special lenses to work with such glassware. The tiltable illuminator stand allows you to observe cell cultures in high Petri dishes or in cylindrical flasks up to 165 mm. Observations are carried out in transmitted light, research methods are bright field and phase contrast. Two independent visualization channels allow for simultaneous connection of a monitor and camera. The microscope is used for teaching in universities, routine laboratory work and scientific research. Fields of science: medicine, biotechnology, biology, virology, agriculture, ecology, toxicology, pharmacology and others. Digital camera The MAGUS CDF30 digital camera is designed to work using light and dark field methods. It is characterized by low noise level and high light sensitivity. The camera is equipped with an 8.3 megapixel sensor and produces a realistic image in 4K resolution (3840x2160 pixels), in which very small details of objects and their structures are clearly visible. The camera is recommended for use with 4x, 10x and 20x lenses, as well as a stereo microscope. At maximum resolution, video is recorded at a frequency of 45 frames per second. This is enough for conducting demonstrations in the classroom, fine-tuning the focus of a microscope, recording fast processes and observing moving objects. At Full HD resolution (1920x1080 pixels), the frame rate increases to 70 frames per second. The transitions between frames become softer, the camera records very small movements of the drug. The camera is equipped with a USB 3.0 interface. Data transfer speed is 10 times faster than cameras with USB 2.0 interface. The high-speed camera is recommended for professional work in the laboratory, research or teaching at universities. Visual attachment The optical length of the tube is infinity. When assembling the microscope, the user rotates the nozzle tubes 180° and selects the height of the pupil relief in accordance with his own height. The visual attachment is trinocular. The monitor is installed in the vertical tube of the visual attachment, and the digital camera is installed in the side visualization channel on the microscope body. The light flux on the trinocular head is switchable 50/50 (imaging channel is open) or 100/0 (imaging channel is closed), on the body – 100/0 or 0/100. Revolving device The revolver for 5 lenses is mounted on a tripod under the table. An additional phase lens can be installed in the free slot of the revolver, which will allow one more magnification for the phase-contrast research method. Lenses Planachromatic infinity lenses with an increased working distance are adjusted to the thickness of the pan bottom of 1.2 mm. 3 lenses are used to work using the bright field method and one lens is used to work using the phase contrast method. Focus Coaxial coarse and fine focusing knobs are located at the bottom of the body on both sides of the tripod. The user places his hands freely on the table and takes a relaxed position while working. Focus is adjusted smoothly and effortlessly. On the right side there is a coarse focus locking handle for quickly adjusting the microscope after changing the object of study. On the left is a ring for adjusting the rigidity of the coarse focusing stroke for comfortable individual settings. Subject table A special mechanism for moving laboratory glassware in two mutually perpendicular directions is installed on a fixed object stage. Smooth, subtle movement of the object will ensure the accuracy of the research - not a single section of the object under study will be missed. The travel handle is low, so the user does not strain his right hand. The microscope kit includes four cup holders for different sizes of dishes. Condenser Phase-contrast condenser with 4 positions: a free hole is used for bright-field observations, three with phase inserts - for working on phase lenses with magnifications of 10x, 20x and 40x. The phase rings are centered. Quick and intuitive switching from one research method to another saves time and simplifies the researcher's work. Light source The halogen lamp emits light at a color temperature that is comfortable for the eyes. The 30-watt lamp produces enough brightness to work with all brightfield and phase contrast lenses. Köhler lighting Correct adjustment of the microscope according to Köhler improves the quality of the image of the object. With this lighting, the resolution limit on each lens is reached. Uniform illumination of the field of view without darkening at the edges. The object of interest is brought into focus and the artifact images are removed. Accessories A line of accessories has been developed for the microscope. Additional 20x and 40x phase objectives are used for studying non-contrast objects with sizes of 0.7 µm and 0.4 µm. Eyepieces extend the magnification range of the microscope. An additional pair of eyepieces will help realize useful magnification on a lens that is used more often for work.
