DescriptionUC Davis Engineers Invent Viscous Fluid Shaker for COVID-19 Saliva Samples - 51397120497.jpg
English: Engineers in the UC Davis Department of Biological and Agricultural Engineering developed a machine that shakes and inverts viscous samples to combine them with proteins that make them less sticky. The machine was invented for UC Davis’ award-winning asymptomatic COVID-19 saliva testing, but can be used in any situation where viscous liquids need to be evenly mixed with another substance.
