Abstract: | The design characteristics of the optical cuvette suggested here provide the possibility of accomplishing the uniaxial orientation
of gels with retention of the constancy of their volume, which makes it possible to carry out highly accurate polarization
measurements with commercial spectropolarimeters in directions parallel and perpendicular to the axis of orientation. Using
as examples polyacrylamide gels containing biologically important molecules and membranes, the possibility of measuring absorption
spectra, the linear dichroism, and the dispersion of optical rotation is demonstrated.
