field. Hence, only an approximate analysis of non-Newtonian systems
is possible, which relies heavily on the method of calibration.

2 . 8 . 1 . 5 Capillary rheometry

Capillary rheometry has a well-defined flow, and it is more sensitive
for high viscous material than the cone-and-plate and parallel plate
systems. In addition, it can reach high shear rates, and it is possible to
correct raw data to account for any wall slip. Its main disadvantage is
that temperature control is difficult; hence, only approximate analysis
of non-Newtonian systems is possible. This geometry is susceptible to
phase separation in material, which could lead to wall slip.
