Cell Stress Measurements

World Precision Instruments

The Cell Tester cell biology research tool allows researchers to study the influence of mechanical force, stress, or strain on cells and how these cells react to stimuli. Working at a rate of over 1,000 measurements per second, the Cell Tester employs optics, nano positioning, and force sensor technology to deliver reproducible force measurements. This facilitates the quantification of the small forces that individual cells can generate—in the order of tens to hundreds of nano grams. At the same time, the instrument uses miniature piezo crystal-based motors to push or pull cells and so changes their length or imposes stress.
