It is no secret that dogs have long been used for purposes other than companionship. Because of an acute sense of smell, dogs can be trained in medical arenas to detect cancer, diabetes, and other chronic diseases or conditions. You may have also seen the incredible sniffing power of dogs used in missing persons cases, illegal drugs, and hunting applications. Therefore, researchers are now expanding upon this innate ability to train them to detect COVID-19.  

The overall hope is for dogs to be able to detect COVID-19 in patients that are not yet displaying any symptoms. The thought process is basically to use this tool as a large-scale screening process for highly populated areas such as airports, sporting events, and recreation areas. [1] 

“Who lives here now? and “Who lived here previously” are fundamental questions of biology, but observing living things in their natural habitats is not always so straightforward. Tracking down rare, elusive, and microscopic species through harsh or inaccessible environments has challenged biologists for centuries.

What is an oleophobic membrane? 

Etymologically, the word oleophobic translates as “fears oil”.  An oleophobic membrane is a membrane that resists capillary flow wetting by, and consequently repels, oils and other low surface tension fluids.  Oleophobicity is typically achieved by using proprietary chemical treatments to develop a permanent coating on the membrane surfaces that is essentially less attractive to oil molecules than they are to themselves. Resistance to solvent wetting by oleophobic membranes is typically characterized using AATCC Test Method 118. 

Sterlitech now offers five different bench-scale crossflow cell assemblies to meet your specific, experimental needs. In addition to the rectangular crossflow cells, the Innovator CF016, the Explorer CF042, and the Developer Sepa, the two, new circular designed CF047 and CF090 cells are rounding out the product line. Both have a 316 stainless steel cell body,  maximum operating pressure of 69 bar (1000 psig) at 22°C, (71.6°F), and a maximum operating temperature of 150°C (302°F). Available in two sizes, the cells will assist researchers in scaling up to larger membranes.

Pioneer CF047

Active membrane area: 14.6 sq. cm

Researcher CF090 

Active membrane area: 53.0 sq. cm

The Rocker Lafil 200 vacuum suction system integrates a vacuum source with a 4L waste bottle and suction kit, saves 50% space and is ideal for large volume cell culture aspiration and reduces the number of times you have to empty the waste bottle. 

The Rocker Lafil 100 system is great for smaller volume cell culture aspiration. This system allows users to efficiently draw washing solutions from microplates, supernatant after centrifugation, or media from cell culture.
