The analytical choice in most laboratories is the rotational viscometer
, which measures the viscous drag on a rotating disk having a known spacing to the cylinder containing the sample being measured.
The primary goal of the initial testing program was to compare the solid-state viscometer
to existing ASTM methods.
performed reliably and was accurate to within [+ or -]10% of the laboratory reference viscosity.
Glass capillary viscometers
are often used in quality control applications for the oil & gas, plastics, and organic chemistry industries.
Like the kingdom searching for a princess sensitive enough to be kept awake by a single pea, segments of the food industry are seeking an in-line viscometer
that is sensitive and consistent when processing highly viscous, non-Newtonian fluids with particulates.
Tenders are invited for Procurement Of Viscometer
(Oil Bath) Provided With Microprocessor Temperature Control Between Ambient And 150 Deg.
The DV-100 disposable viscometer
with tube and 7-sample preheating block reduces testing time since instrument cleaning is not required.
With the push of a button, the viscometer
glides up and down, allowing for quick positioning, rapid sample change and improved laboratory efficiency.
One of the three instruments is a high speed cone/plate viscometer
(as described in D4287, "High-Shear Viscosity Using a Cone/Plate Viscometer
") that provides useful data related to brushability and sprayability.
says its new viscometer
line features three models, each of which is suited for a unique user requirement: the Thermo Scientific Haake Viscotester E ("the expert model"), for automatic flow curve measurements with full PC control; Viscotester D ("the distinct model"), for routine viscosity measurements with data transfer; and Viscotester C ("the convenient model"), for manual viscosity measurements.
The vacuum on the eight-screw MRS device is controlled by an in-line viscometer
located before the melt pump that feeds the die, The viscometer
sends a signal to raise or lower the vacuum to maintain consistent melt viscosity.
