viscometer
/vɪsˈkɒmɪtə
/noun
An instrument for measuring the viscosity of liquids.Rheological properties were measured using a capillary viscometer recording shear stress - shear rate relationship....
- The Spectro technicians also use viscometers to test the viscosity of engine oil.
- The steady-shear surface viscosity was measured in a custom built magnetic needle viscometer.
Derivatives
viscometric
- The combination of the minicapillary viscometer and the new viscometric measurements is practical in the study of DNA-lipid complexes, and possibly other particles including liposomes and bioactive polymers.
- In addition, viscometric measurements perturbed assembly by fragmenting filaments.
- For the estimation of cellulase activity, carboxymethyl cellulose with a degree of substitution of 0.4 was used as a substrate in viscometric assays.
viscometrically
- ß-Glucan endohydrolase activity was measured viscometrically at 40°C, using water-soluble barley ß-glucan as substrate.
- A quantitative study to follow the time course of lipoplex maturation will be possible viscometrically using Eqs. 5 and 6.
- The degree of polymerisation was determined viscometrically, while diffuse reflectance FTIR was used to gain insight into the changes in the chemical composition.
viscometry
- Our studies of BIA-DNA interactions by isothermal titration calorimetry and viscometry were not successful mainly because of insufficient solubility of the imidazoacridone compounds in water (data not shown).
- Except for the lowest molecular weight samples, all of the average molecular weights were determined by agarose gel electrophoresis or viscometry.
- In some cases intercalative ability has been confirmed with the ethidium displacement assay or viscometry.
Origin
Late 19th century: from late Latin viscosus 'viscous' + -meter.
