Investigating Variation in Flow from Peristaltic Pumps

Peristaltic pumps find wide application in modern labs, they are considered inexpensive, easy to use and maintain and, most important of all, are extremely reliable and flexible. The range of application is huge, from simple transfer of a liquid from one container to another in HPLC and Ion chromatographs, to more complex usage as dispensing tools for reagents in flow chemistry. Despite all known limitations related to inferior performance in presence of high back pressure, peristaltic pumps can be considered the ‘go to’ choice for lab pumps, easy to adapt to specific tasks just by the selection of different tube internal diameter (I.D) and materials.

Scientists Unveil Least Costly Carbon Capture System to Date

The need for technology that can capture, remove and repurpose carbon dioxide grows stronger with every CO2 molecule that reaches Earth’s atmosphere. To meet that need, scientists at the Department of Energy’s Pacific Northwest National Laboratory have cleared a new milestone in their efforts to make carbon capture more affordable and widespread.

Domestic Cats Avoided Mating with European Wildcats

Research studies have revealed that in spite of domestic cats being introduced to European wildcats for over 2000 years, they avoided mating with each other. However, 50 years ago, the rates of interbreeding between wildcats and domestic cats rose rapidly. Researchers believe that this may have happened due to the decreasing wildcat populations and a lack of opportunity to mate with other wildcats.
