The free fall machine (FFM) is designed to permit the development of small biological sample such as cell cultures without the effect of gravity under free fall conditions [Schwarzenberg M, Pippia P, Meloni MA, Cossu G, Cogoli-Greuter M, Cogoli A. (1999). Signal transduction in T lymphocytes--a comparison of the data from space, the free fall machine and the random positioning machine. Adv Space Res. 24(6): 793-800] .

Description

The free fall machine (FFM) addresses some of the problems of the simple horizontal clinostat. In a typical machine samples are allowed to cycle between free fall for about a metre down a column (0 g) and a "bounce" back to the top of the column that is intended to be so fast (20 g) that it is undetected by the biological sample. The sample therefore effectively grows at 0 g.
