Optimized Hygienic Bubble Trap Level Control

Learn how externally mounted point level sensors eliminate contact with process fluids, CIP, SIP and hygienic requirements.

This white paper, authored by Dan Klees, a bioprocess industry expert and thought leader, evaluates the effectiveness of a non-contacting capacitance level probe for measuring and controlling the point level in a hygienic bubble trap. Unlike process contact technologies, this probe is mounted to the outside of the bubble trap; as a result, it does not make physical contact with the process fluid.

This means there is no need to account for certain regulatory requirements, such as Clean in Place (CIP) and Sterilize in Place (SIP), to preserve the hygienic purification process. We have used the VEGA VEGAPOINT 21® capacitance point level probe on an LJ Star® Hygienic Bubble Trap and found it to be an effective, reliable and scalable method for controlling the point level.

This offers a convenient solution for many downstream biopharmaceutical processes, such as chromatography, that rely on the use of hygienic bubble traps to separate gas bubbles from the fluid phase for an effective operation.
