Olympus CK2 Inverted Phase Tissue Culture Microscope

The Olympus CK2 is one of the most widely used inverted phase contrast microscopes ever produced, with a proven track record in cell biology and tissue culture laboratories worldwide. This base configuration delivers everything needed for routine cell culture observation in a compact, reliable platform. 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. The binocular head with 10x eyepieces provides comfortable, ergonomic observation for daily use. In excellent condition, this is the most cost-effective entry point into the Olympus CK2 platform — ideal as a primary observation station or a dedicated satellite microscope.
