Olympus CKX53 Inverted Tissue Culture Microscope with 40x

The Olympus CKX53 is Olympus's modern inverted cell culture microscope, designed from the ground up for the demands of live cell biology. Its inverted configuration places the objectives below the stage, allowing direct observation of cells growing in flasks, dishes, and multi-well plates without disturbing the culture environment. The LED illumination system delivers stable, uniform light with minimal heat output — critical for maintaining cell viability during extended observation sessions. The four-objective turret provides a complete magnification range: a 4x brightfield objective for low-power culture surveys, and 10x, 20x, and 40x long working distance phase contrast objectives for detailed morphological assessment without cover slips. Phase contrast optics reveal intracellular structures, cell boundaries, and motility in unstained living cells with exceptional clarity. The integrated camera port enables seamless connection to C-mount cameras for documentation, time-lapse imaging, and quantitative analysis. This unit has been professionally refurbished and is in excellent optical and mechanical condition.
