My name is Ecko Chen, and I am the Mechanical Engineer here at RheoSense. My coworker Brandon has introduced a consumable list for the VROC® Initium maintenance in the previous post. I am going to expand a little on one of the most common consumable replacements --- The septa.
Starting this month, we're excited to announce the production of a new series of videos on our fully automatic, high throughput viscometer: VROC® Initium. In the first half of the series, our specialists and Initium production engineers explain step-by-step on how to correctly and safely set up and configure your instrument. Each instructional video will range anywhere from 3 minutes to 10 minutes. Each video includes tips or other helpful information to ensure optimal functionality and capabilities of your VROC® Initium. We are more than happy to answer any questions you may have, as well as creating additional media content topics suggested from you, our clients.
My name is Brandon Bell and I am the Process Engineer here at RheoSense. I am responsible for the production of the VROC® Initium product line and I wanted to take a few minutes to provide you a few tips and tricks that I have picked up to help you get the most out of your instrument.
We frequently get the question, "how do I know that my equipment is working, or that these tests are accurate?" The best way to determine this and be sure of your results is to run a system suitability test.
Hello! We are pleased to announce that we are releasing a major software update for the VROC® Initium, software version 1.4.1. This software update includes a new user interface (UI) and the ability to export databases.
For any medication sold over the counter of your local drugstore to the medication you are prescribed, you can bet that all of those drugs are approved by the U.S. federal food and drugs administration (FDA). "The FDA is responsible for protecting the public health by assuring the safety, efficacy, and the security of human and veterinary drugs, biological products, medical devices, the nation's food supply, cosmetics and products that emit radiation" (FDA). Providing federal guidelines for almost everything consumed, medication is but one spectrum of what the FDA regulates.
We are all familiar with maintaining our lab instruments, but how often do we perform maintenance on our lab methods or SOPs?
In the upcoming weeks, we are proud to announce the release of our latest application note regarding concentration dependence in protein viscosity. In this app note, Dr. Stacey Elliott gathered viscosity data for Bovine Gamma Globulin (BgG) formulations over the full concentration range, including therapeutic levels ≥ 100 mg/mL, using the VROC®Initium. The solution buffer included sucrose which is a common additive to enhance stabilization during freeze-drying and storage. Relative viscosity versus concentration curves were fit with the Ross-Minton equation which is a frequently used analysis tool for protein formulations.

According to a GEN – genetic engineering & biotechnology article, researchers found that the consumption of coffee stimulates the complex network of neurotransmitters, also known as the endocannabinoid system (ECS), much like that of cannabis. ECS consists of a biological structure composed of endocannabinoids, which are essentially the "small molecules that activate the cannabinoid receptors" (Jikomes). ECS is a system that is necessary in maintaining homeostasis on a cellular level. Furthermore, ECS is also responsible as it acts as a regulator for stress response, appetite, addiction, energy, and much more (GEN).
Measuring viscosity dates back to as early as the 19th century. French physicist Jean Poiseuille discovered the concept of measuring viscosity by formulating the "mathematical expression for the flow rate for the laminar flow of fluids in circular tubes." Later on, this formulation was discovered by a German hydraulic engineer Gotthilf Hagen, which came to be known as the Hagen-Poiseuille equation (Britannica). Early measurements of viscosity focused primarily on the flow of blood. Measurements were conducted using the hemodynamometer that incorporated narrow tubes & glass capillaries in effort to measure the pressures in the arteries of horses and dogs (Sutera).
