Olympus CK2 Inverted Phase Microscope w/stage

The Olympus CK2 is a classic inverted phase contrast microscope with a proven track record in cell biology and tissue culture laboratories worldwide. This configuration adds an XY mechanical stage — enabling precise, repeatable specimen positioning that is essential for revisiting specific regions of interest, screening multi-well plates, and systematic field-by-field observation. Its inverted design places objectives below the stage, providing unrestricted access to culture dishes, flasks, and multi-well plates without disturbing living specimens. Three objectives cover the core tissue culture workflow: the 4x brightfield for wide-field specimen survey, 10x phase contrast for routine cell monitoring, and the 20x long working distance phase contrast objective for detailed cellular imaging through standard culture vessel walls. The ULWCD 0.3 N.A. condenser with integrated phase contrast slider delivers clean, high-contrast phase imaging at both 10x and 20x. In excellent condition, this is an outstanding value for any cell culture laboratory requiring precise stage control.
