Through meticulous customer relationship development and continuous exploration of new applications, Lu has been able to provide a level of outstanding customer service and support.

 What do we talk about when we talk about viscosity? A series stories of viscosity in life.

Calibration/General Maintenance for your viscometer

Did you know that even a deadweight machine that is capable of applying 4,448,222 Newtons or 1 million pounds of force?

Things Scientists Say...

Science is the study of the world using collected knowledge, observation, and experimentation. Those in the sciences are generally known for being quite serious, dare I say, dull. However, that is not always the chase. Take for example Albert Einstein, unquestionably one of the most brilliant minds to ever inhabit the earth, but also a wit and sense of humor maybe equally as impressive. In this blog, I’d like to share some funny Einstein quotes as well as quotes from other brilliant minds. Enjoy!

Visualizing Viscosity

One of the challenges of creating monoclonal antibody (mAb) injectable drugs is optimizing formulation. A good formulation has to have a high concentration of stable mAb’s for high efficacy. There are a variety of factors that can affect stability of these mAb’s, temperature, shear forces, pH, and even concentration. When proteins become, unstable and denature they can increase the viscosity of your formulation. Using a simple modified parallel plate demonstration, we can visualize why denatured proteins increase viscosity.

Vape Pens & "High" Viscosity

As marijuana use becomes more mainstream, the use of vaporizer pens or vape pens as a delivery system for THC is steadily increasing in popularity. Vape pens are not your classic bongs as seen in some old school Cheech and Chong movies, but are in fact a high-tech device; a high-tech device where precision and accuracy are critical to performance.

What Happens if You Stir a Cup of Zero Viscosity Coffee?

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.
