What happens when your samples are out on the sample tray for quite some time? When it comes to working with well plate or vial rack systems, your samples could be on the plate/rack for a long time prior to the measurement. As a result, we conducted some studies to see just how much evaporation effects occur specifically with our VROC® technology.
We recently took two commercially available cannabis oil cartridges used to refill cannabis pens and measured the viscosity. The two main differences were the variation in THC and CBD Oils. Sample 1 had 78% THC and 0.29% CBD content. Sample 2 had 80 % THC and 0% CBD.
Mother's Day is coming up on May 12, 2019. Don't forget to send some appreciation and enjoy a recipe for Angel food cake we found online written by Laura Kurella. She also references 'viscosity,' when explaining the texture of the batter. For convenience, we have copied the recipe below:
Excipients are a substance that is often added to protein formulations to serve as a medium for the proteins or active substance in the formulation. While commonly perceived as inert and just a supplement to improve the formulation or become a diluent, adding excipients have sometimes created a reaction of the ingredients in the formulation and according to the NPS Medicinewise article*, such reactions have resulted in various reactions in patients as well.
On April 12, 2019, a new paper, "Effective Vaccination against Middle East Respiratory Syndrome Corona-virus," that focuses on the threat of emerging infectious pathogens and methods to develop vaccines to combat has been published. Diving into further details into pathogens such as Middle East respiratory syndrome corona-virus (MERS-CoV), it is important to understand the history of the disease, MERS.
One of the most commonly asked questions from our customers is the topic of shear rates and what to expect when dealing with various applications. Now most of you have a general idea on what shear rate means, but we want to take it one step further and illustrate several key components when dealing with shear rates.
One of the common questions we get from our customers is, “Which chip do I use to test my fluid?” RheoSense has a variety of different chips and you may wonder which chip would be the best for your application. The m-VROC® has four different designations of chips: A, B, C, and E. These letter values reference the max pressure capability of the MEMS pressure sensors inside the microfluidic flow cell. With the A-series being able to measure the lowest pressures for low viscosity fluids, the E-series are able to measure the highest pressures for higher viscosities and higher shear rates.
