Tenders are invited for procurement of rotational viscometer
and accessories for measuring viscosity of bitumen
investigate the rheological properties of blended cement pastes using a rotational viscometer
and a dynamic shear rheometer.
There are two types of rotational viscometers
commonly used in the assessment of paints, the Krebs Viscometer and the Rotational Viscometer
Another device for measuring the rheology of fine suspensions is the rotational viscometer
. There is an Anton-Paar rotational viscometer
at our institute (cylinder-cylinder and cone-plate test systems, 50 [cm.sup.3] sample volume, 0.007-7 Pas viscosity and 40-1200 1/s shear rate measuring range).
In this study, rheological properties of grape juice were measured by using a rotational viscometer
in three temperature of 25, 45 and 65[degrees]C and three Brix values of 35, 50 and 76.
Even something as apparently mundane as paint requires that pigments are well mixed in for an even colour and that the correct consistency is attained for easy application.There are a number of different technologies available for measuring viscosity, but one of the most popular and widely used is the rotational viscometer
, which measures viscosity by monitoring the torque required to rotate a spindle at a constant speed within the fluid.
The work horse in the viscosity measurement world for QC testing on pharmaceutical liquids and semi-solids is the rotational viscometer
. The operator attaches the spindle specified in the test method, conditions the sample to the recommended temperature, turns on the motor at the defined speed and records the viscosity result in centipoises.
Apparent viscosity (AV), plastic viscosity (PV), and yield point (YP) were measured by rotational viscometer
(ZNN-D6, China) at different temperatures.
The goal of research was to investigate the effect of the current content of cement modifiers and polycarboxylate ether based plasticizing admixture on the rheological properties of cement pastes using a rotational viscometer
with co-axial cylinders.
One of the most widespread cement paste rheological characterization techniques is based on the use of a rotational viscometer
with coaxial cylinders.
In this connection the nature of interactions of the given polymer-clay systems was investigated by employing methods such as equilibrium swelling, the sediment analysis, rotational viscometer
, scanning electronic microscopy, and electrophoresis.
ColeParmer has introduced a new Rotational Viscometer
series designed to offer greater chemical resistance and enable instruments to handle chemically corrosive materials.
