Efficient PFAS-free degassing of aqueous solutions

Biotech Fluidics has introduced the DEGASi® life science degassing chamber that provides efficient degasification of aqueous liquids at flow rates up to 20 ml/min.

Toxic poly- and perfluoroalkyl substances (PFAS) are known to be highly persistent in the environment and linked to health problems in humans, including higher cholesterol, lower birth weights, and kidney cancer.

Traditionally most degassing systems have used fluorinated polymer membranes to ensure wide chemical compatibility. However, reflecting the growing demand from environmental, food and healthcare labs to avoid PFAS, the new life science degassing chamber has been designed with a fluid path lined by a silicone membrane thereby eliminating the chance of contamination by these toxic substances.

The DEGASi® life science degassing chamber is designed to improve analytical instrument precision and assay quality by removing dissolved gases from aqueous fluids before they outgas and form bubbles that impact precision dispensing or interfering with detection.

The core functional element of the life science degassing chamber is a fluid path lined by a highly permeable silicone membrane. Fluid flows through the membrane pathway while the space surrounding the membrane is evacuated. A PID controlled vacuum pump holds a precise vacuum level driving the active removal of dissolved gases across the membrane. As a result, these degassing chambers provide a valuable tool for actively removing dissolved gases from aqueous fluid streams before they form bubbles, ensuring maximum analytical uptime and performance.
