For small angle X-ray scattering measurements a sample holder was construct
ed. This unit can be used as a shear cell. In the paper the construction an
d the first application of the shear cell are presented. Non ionic surfacta
nt (C(13,15)E7) - water system was investigated during shearing stress unde
r different temperatures. The scattering curves reveal the tixotropic behav
iours of the system, which are observed on the rheological measurements, to
