What do we talk about when we talk about viscosity? A series stories of viscosity in life.
Story One - Cosmos and Cosmetics
Unlike height and weight, which people have a good sense about based on common items, viscosity is much harder to describe.
First of all, the question is-- can there be a coffee or liquid with zero viscosity coffee? We know that there is negative viscosity. Is having zero viscosity similar?
Viscosity is the resistance of a fluid to flow and it comes from the friction of molecules as they move against each other within the fluid. All fluids have at least some resistance to flow – except super fluids.
Intrinsic viscosity is an important tool in the fields of polymer and protein research. Intrinsic viscosity allows for determination of molecular weight and size more reliably than dynamic light scattering. Small sample m-VROC™ viscometer is an ideal tool to measure intrinsic viscosity of samples. The high accuracy, low sample volume requirements, and high speed of measurement ensure that data collection is fast, simple, and accurate.
The higher concentrations required to reduce dose frequency in modern therapeutics often lead to high
