What is meant by thixotropic?

Definition of thixotropy : the property of various gels of becoming fluid when disturbed (as by shaking) … says that blood liquefaction can be explained in terms of a phenomenon called thixotropy.

What is a thixotropic solution?

A thixotropic solution at rest is a weak, often pourable, gel. In other words, a thixotropic solution has properties of a gel (at rest) and properties of a fluid when a shear force is applied. Alginates (Chapter 14). are examples of hydrocolloids whose solutions can exhibit thixotropic behavior.

What is thixotropic penetrant?

Thixotropy is a time-dependent shear thinning property. Certain gels or fluids that are thick or viscous under static conditions will flow (become thinner, less viscous) over time when shaken, agitated, shear-stressed, or otherwise stressed (time-dependent viscosity).

What is a thixotropic material?

Thixotropic materials display a viscosity that decreases with shear rate and time of shear as well. They possess a solid structure that requires time to form under high pressure (or low temperature) and that structure is disrupted by shear stress.

What is thixotropic gel used for?

A thixotropic gel-like composition comprising liquid polybutadiene and an inorganic inert filler dispersed therein is adapted for use as a sealing barrier between separated phases of differing densities of a fluid in which said composition has at rest a density intermediate said differing densities, said gel-like …

Where is thixotropic gel found in serum separators?

In this blood serum separator tube 10, the thixotropic gel 16 is exposed to any atmosphere 22 contained in the tube 10 at an annular surface 25 around the gel energizer 18, between the energizer 18 and the inner wall 13 of the tube.

What is thixotropic gel made of?

What is the purpose of thixotropic gel?

Thixotropic gel forms a barrier between blood cells and serum or plasma, thus preventing contamination and allowing easy separation. Glycolysis is a cellular reaction used to harvest energy from glucose. Blood specimens used for analysis are whole blood, serum, and plasma.

Which tube contains thixotropic gel?

Blood Collection Tubes and Additives

Is thixotropic gel an additive?

Borchi® Gel NA thixotropic additive is a VOC-, APEO-, and tin-free organic zirconium complex neutralized with sodium hydroxide. Benefits include highly effective storage stability, as well as the prevention of settling and separation.

The A thixotropic material becomes more fluid as the duration of structure of an emulsion or polymer is governed by the random applied forces, such as stirring, pumping or shaking, increases (i.e., the distribution of droplets or the degree of entanglement, respectively. The work softening process) (Fig. 2).

Can thixotropic formulations be used as drug delivery systems?

What are the best books on thixotropy?

What is the difference between viscosity and thixotropic index (TI)?

Viscosity and Thixotropic Index (TI) are common terminology used to describe the rheology of an epoxy. They both play a large role on how a product will perform for a particular application. Viscosity is a measurement of a fluid’s resistance to flow and is measured in Poise or more commonly centipoise (cPs). One
