The chamber removes dissolved gases from aqueous fluid streams to prevent the formation of bubbles
Biotechnology company Biotech Fluidics has unveiled the Degasi life science degassing chamber, which provides degasification of aqueous liquids at flow rates up to 20ml per minute.
The Degasi chamber removes dissolved gases from aqueous fluid streams that can be detrimental to any fluidic system. The gases can form bubbles that impact precision dispensing and interfere with detection.
In fact, a single bubble in a nanoscale liquid dispenser or pumping system can ruin an entire operation’s precision and accuracy.
A PID-controlled vacuum pump holds a precise vacuum level driving the active removal of the dissolved gases across the membrane. This helps to improve the accuracy and performance of analytical measurements and industrial processes.
Traditional degassing systems mostly use fluorinated polymer membranes to support wide chemical compatibility. However, toxic poly and perfluoroalkyl substances (PFAS) linger in the environment, causing health problems such as high cholesterol, kidney cancer and low birth weights.
“The core functional element of our Degasi life science degassing chamber is a fluid path lined by a highly permeable silicone membrane," said Biotech Fluidics CEO Anders Grahn. "Most inline degassers use fluorinated polymer membranes to ensure wide chemical compatibility but these also risk contamination with trace amounts of PFAS."
The chamber's silicone membrane eliminates the chance of contamination by these toxic substances. Fluid flows through the membrane pathway while the space surrounding the membrane is evacuated.
Last year, Biotech Fluidics released several additions to the Degasi line, including the Plus Nano and Plus ultraNano, helpful for biomolecular research, energy conversion, medicine and water desalination.
