Product Description
Biological microscopes play a crucial role in scientific research and educational environments. The YR05789 and YR05790 models from Kalstein offer advanced optics and ergonomic design for precision and ease of use. The Seidentopf Binocular Head in the YR05789 and the Seidentopf Trinocular Head in the YR05790 provide inclined viewing at 30 degrees and full 360-degree rotation, allowing comfortable long-term observation with adjustable interpupillary distances. Upgraded eyepieces with a 30mm diameter offer diopter adjustments, enhancing visualization.
The quintuple nosepiece permits users to equip the microscope with up to five objectives, allowing magnifications from PLAN 4X to PLAN 100X, with options for both oil and water immersion. The large, rackless mechanical stage, measuring 182x140mm, ensures stable and smooth specimen manipulation. Illumination is robust, using a 6V30W halogen Koehler system, supplemented by a blue filter, while also supporting eco-friendly, low-voltage power options for outdoor usage.
