Capillary rheometers are especially advantageous for characterization of therapeutic protein solutions since it determines the ability to be syringed. [6] Additionally, there is an inverse relationship between the rheometry and solution stability, as well as thermodynamic interactions. Rotational geometries of different types of shearing rheometers
Capillary breakup rheometry is an experimental technique used to assess the extensional rheological response of low viscous fluids. Unlike most shear and extensional rheometers, this technique does not involve active stretch or measurement of stress or strain but exploits only surface tension to create a uniaxial extensional flow.
Rheometry (from Greek ῥέος (rheos) 'stream') generically refers to the experimental techniques used to determine the rheological properties of materials, [1] that is the qualitative and quantitative relationships between stresses and strains and their derivatives.
Measuring principle: The slit viscometer/rheometer is based on the fundamental principle that a viscous liquid resists flow, exhibiting a decreasing pressure along the length of the slit. The pressure decrease or drop ( ∆ P ) is correlated with the shear stress at the wall boundary.
It is a new way of doing rheology, traditionally done using a rheometer. There are two types of microrheology: passive microrheology and active microrheology . Passive microrheology uses inherent thermal energy to move the tracers, whereas active microrheology uses externally applied forces, such as from a magnetic field or an optical tweezer ...
Rheology (/ r iː ˈ ɒ l ə dʒ i /; from Greek ῥέω (rhéō) 'flow' and -λoγία (-logia) 'study of') is the study of the flow of matter, primarily in a fluid (liquid or gas) state but also as "soft solids" or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force.
Much like the Meissner-type rheometer, the SER rheometer uses a set of two rollers to strain a sample at a given rate. [31] It then calculates the sample viscosity using the well known equation: σ = η ϵ ˙ {\displaystyle \sigma =\eta {\dot {\epsilon }}} where σ {\displaystyle \sigma } is the stress, η {\displaystyle \eta } is the viscosity ...
Jurin's law, or capillary rise, is the simplest analysis of capillary action—the induced motion of liquids in small channels [1] —and states that the maximum height of a liquid in a capillary tube is inversely proportional to the tube's diameter.
