Abstract
Two variants of a sample holder were constructed for SAXS (small angle X-ray
scattering) and freeze fracture studies of colloid systems during shear
stress. The detailed construction of both variants is described. The SAXS
investigations give information about the structural changes in the range of
nm´s, and the freeze fracture technique makes possible the imaging of the
\mum-scale morphology. Combining these methods the origin of certain
macroscopical features, e.g. shear induced structural formations (like
tixotropy) can be examined in a wide size range of the colloid dimensions
