PCT No. PCT/FR93/00437 Sec. 371 Date Dec. 22, 1994 Sec. 102(e) Date Dec. 22, 1994 PCT Filed May 6, 1993 PCT Pub. No. WO93/22420 PCT Pub. Date Nov. 11, 1993Reactor-type device for placing in contact solid particles with a liquid. The device comprises an enclosure, delimited by walls, to be filled with the liquid and containing the solid particles in contact with the liquid, and an arrangement for supplying and evacuating the liquid from the enclosure. At least one of the walls of the enclosure can be moved, thereby creating a variable volume. The invention also concerns reaction or culture processes using the device.
