BS-2046B
BS-2046T with Ceramics stage
1. High rigidity body structure. Fire-new designed integrative Y-shaped body, all-metal diecasted under high pressure, High image quality with high stability under every magnification observation. Ensures the test precision of multi-channel fluorescence diagnosis.4. Mechanical stage. (1) Standard 175×145mm right-hand double-layer mechanical stage, damping double slice clamp design, can place two slices at the same time for inspection and comparative analysis. (2) Optional 150mm×162mm ceramic spray mechanical stage, which is not only wear-resistant and anti-corrosive, but also can reduce platform deformation caused by temperature changes. (3) Optional 187×166mm super large double-layer mechanical stage, two-way linear rail transmission, left and right hand positions are optional.
3. Screwdriver storage device. The screwdriver storage device makes full use of the space of the microscope, the screwdriver at users’ fingertips enables users to improve work efficiency.5. Safe carrying design. The rear side of the microscope has been designed with a handle position, which makes it safe and easy when carry the whole microscope.
