title: The slow rotating centrifuge microscope NIZEMI--a versatile instrument for terrestrial hypergravity and space microgravity research in biology and materials science.
abstract: NIZEMI (slow rotating centrifuge microscope) is a tool for optical investigations of small biological and non-biological specimens during variable accelerations.  Two laboratory models for ground research designed for accelerations from 1 to 5 x g and 10 x g respectively are used for terrestrial research, especially in gravitational biology.  A space facility was developed and built for the Spacelab mission IML-2 during which eight experiments were performed successfully.  The specifications and topic design features of the NIZEMI models are presented in this paper.
