MAGUS Bio V300 is a biological microscope of an inverted design for studying samples in laboratory ware up to 70 mm high and with a bottom thickness up to 1.2 mm. The objects of study can be colonies of cells, tissue cultures, biological fluids, etc. The samples do not require mandatory pre-staining. The observations are made in transmitted light. Microscopy techniques: brightfield and phase contrast. The microscope is suitable for routine and research work, and teaching.


The microscope is equipped with a classic trinocular head, the trinocular tube is used for mounting a digital camera. The camera is not included in the set. The beam splitting is 50/50.
Four included or additional objectives can be mounted in the revolving nosepiece. All objectives are designed to be used with laboratory ware and have a long working distance. There are 3 plan achromatic objectives for brightfield and 1 plan achromatic objective for the phase contrast technique.


The transmitted light source is a 9W LED. The high power of the LED makes the illumination of the working area bright enough to work with all objectives and with any microscopy technique. The brightness adjustment does not change the color temperature. The LED lifetime is about 50,000 hours without LED replacement.
The condenser has a slot for a phase contrast slider (included). The phase contrast rings can be centered. The installation of the slider saves time when switching between the microscopy techniques.

Stage and focusing mechanism

Fixed mechanical stage. It is equipped with a dish holder (three dish holders of different sizes are included). The dishes can be moved along the X and Y axes by a mechanical attachment. The coaxial coarse and fine focusing mechanism provides accurate and fast focusing. The coarse focusing has a lock mechanism and tension adjustment.


The optional accessories line includes phase objectives, eyepieces, digital cameras, and calibration slides.
