Specifications include, but are not limited to:. FREESTANDING BENCHTOP MICROSCOPY FOR AUTOMATED FLUORESCENT IMAGING: The University of Wisconsin-Madison’s Department of Cell and Regenerative Biology is requesting bids for a Freestanding Benchtop Microscopy that can do basic automated fluorescent imaging for shared use within the department. A self-enclosed dark chamber for visualization is required as the instrument will be installed on a benchtop in the laboratory without a dark room. Because this is a shared system, the microscope has to have an electronic control system with a simple interface that can be used my multiple researchers with minimal training.. 1 The product case must include a specimen enclosure to provide an observation environment that, even without a darkroom, will not impair the background contrast required for fluorescence observation. 2 Excluding the computer and monitor, the installation space of the microscope unit plus lighting source must be within 500 mm (H) x 465 mm (W) x 500 mm (D) when the panel is closed. 3 The product must have a built-in vibration dampening system with the ability to use up to 100x objectives in a typical lab environment. 4 An electronic control system that can be operated with a mouse by multiple users with minimal training is required. 5 The microscope must include, as standard components, an electronic shutter, XY and Z motorized stages, an electronic revolver (to hold 6 objectives from 2x-100x, must be compatible with both Plan Fluor and Plan Apochromat lenses), an electronic filter turret (to hold 4 filters), electronic color camera filter, electronic phase-contrast slit switching mechanism, electronic dimmer filters, and an electronic aperture control; it is necessary that all of these components can be operated with the mouse.
