clinostat
A clinostat is a rotating apparatus used to simulate microgravity conditions for biological materials on Earth. By continuously rotating a specimen about one or two axes, the clinostat averages the effective direction of Earth's gravitational vector over time, reducing the influence of gravity on cellular processes. The device was first developed in the early 20th century by the German scientist Albert Szent‑Györgyi, who used it to study plant root growth under simulated weightlessness.
The basic principle of a clinostat relies on cylindrical or spherical rotation. In a single-axis clinostat,
Clinostats are widely used in plant biology, microbiology, and cell biology to study the effects of microgravity
