CKX53 Culture Microscope


Olympus Corporation (President: Hiroyuki Sasa) announced the international launch by its Scientific Solutions Business of the CKX53 microscope designed to support cell culturing. The CKX53 features clear images and efficient operation. The microscope is available beginning December 2, 2015.

In the fields of regenerative medicine and drug discovery, different types of cells, such as iPS and other stem cells, are produced for research use through a continuous cell culture process. Inverted microscopes designed for live cell observation are used during this process to periodically check cell growth or to capture images of cells as needed. To facilitate the cell culture process, Olympus engineered the advanced and customizable IX3 series of microscopes as well as the compact and lightweight CKX series for quick and easy observation.

The new CKX53 culture microscope is the successor to the CKX41 and CKX31, making it the first full model change in 13 years. While the CKX53 maintains the same excellent optical performance that the CKX series is known for, the new model delivers clearer images and faster startup thanks to features such as a new phase contrast system*1 and LED light source. The CKX53 is approximately 20% lighter than the previous model making it easier to operate for more efficient cell culturing.

Launch Overview

Product Name Launch Date
CKX53 Culture Microscope December 2, 2015

Main Features

  1. Reliable color reproducibility with an LED light source.
  2. Compact and lightweight body with user-friendly operation.
  3. Supports quick cell observation with a new phase contrast system.

Feature Details

1. Reliable color reproducibility with an LED light source.

In place of the halogen bulbs used on previous models, the CKX53 uses an LED light source with a color chosen specifically to suit cell imaging. The LED light source produces crisp cell images with good color reproducibility even when changes are made to the brightness around the viewing field. Furthermore, because the LED light source can be used as soon as the power is turned on, it provides faster cell observation.

2. Compact and lightweight body with user-friendly operation.

Because the CKX53 is approximately 20% lighter than the previous model, it is easier to move the microscope around the laboratory and place it on a clean bench when performing cell observation under aseptic conditions. The microscope is designed for efficient operation, with the controls conveniently placed around the power switch.

3. Supports quick cell observation with a new phase contrast system.

The new phase contrast observation system available on the CKX53 features 4X, 10X, 20X, or 40X magnification using the same ring slit*2 (compared to 10X, 20X, and 40X on the previous model). This provides simple and efficient cell observation at different magnifications without adjustment.

*1 Phase contrast observation is a technique that utilizes the wave nature of light to create light and dark contrast in live cell images. It has been widely adopted as an effective way of reducing cell damage.
*2 Ring slit required for phase contrast observation. On other microscopes, it is common to have to swap the slit for a different one each time the objective is changed.
