The features of determination of vibration viscosity coefficient of concrete mixture by ball viscosimeter
Section 1 required the use of a Brook-field viscosimeter
and a computer spreadsheet program.
A Brookfield viscosimeter
, model Brookfield DV-1I+ Pro, was used for the study of rheological behavior of PDMS systems during vulcanization.
Similar analyses, in , also show a significant increase in viscosity for aged material, while using a rotational viscosimeter
as a measuring system.
The viscosity measurement is made after 25 minutes stirring of the suspension; the temperature stabilization of the suspension at 20[degrees]C is obtained after 30 minutes, then the viscosity measurement is made on a viscosimeter
with the needle n[degrees]4.
The intrinsic viscosity of PLGA fibers was measured at 25 [degrees] C by using a Ubbelohde viscosimeter
The concentration was measured by using an Ubbelohde viscosimeter
of type 1C at 30[degrees]C, while the inherent viscosity (IV, [[eta]]) was calculated by using the Solomon-Ciuta equation (13):

5[degrees]C in a Plexiglas beaker with a static Vibro Viscosimeter
A&D model SV-100.
An Ubbelhode viscosimeter

at 25[degrees]C using an automated Ubbelohde viscosimeter
A two-column GPC V2000 (Waters) equipped with a differential refractometer (DRI) and viscosimeter
(DV) and a multi-angle light scattering (MALS) detector was used to determine the molecular weight distribution (MWD) of the as-received material, the pressed samples and the samples heat-treated in the rheometer.
