Improve the volume precision and dispensing accuracy of your instrumentation by installing a debubbler. This will also eliminate false detection readings and dispense anomalies caused by bubbles. The new Biotech active debubblers can be used in every aqueous-based liquid transferring system where bubbles may occur, but the internal gas-permeable Poridex membrane is not compatible with detergents or emulsifiers. Biotech’s active approach to debubbling offers high operating convenience and low operating costs, suitable for applications within biosensor instrument design and liquid dispensing in areas such as, DNA-sequencing, clinical chemistry, in vitro diagnostics, immunology, hematology, molecular diagnostics, etc. For the more demanding degassing applications and more complex liquid mixtures containing organic solvents or amphiphilic stabilization agents, we recommend the DEGASi PLUS stand-alone degassers or Biotech’s OEM degassing solutions.

A debubbler is a superb tool for removal of visible bubbles from water flow streams not containing organic solvents or detergents. Bubbles in system liquids cause dispense volume anomalies in many instruments and may have severe impact on both dispense precision and analytical accuracy. Biotech’s patented active debubbler design includes a vertical bubble trap, plus a gas-permeable membrane, and a vacuum source.


In equipment where minimized internal volume is critical, a debubbler may not be the optimal choice. For such situations it is possible to prevent bubble formation by actively degassing the systems fluid in the transfer tubing itself. Biotech’s transfer-line degasser employs a unique


For liquid dispensing applications, removing both bubbles and dissolved gases from the flow path improves precision and accuracy, thereby further enhancing overall system performance. By combining active bubble removal with transfer-line vacuum degassing, the Biotech combined debubbler-degasser eliminates existing bubbles and prevents the formation of new ones by also removing the dissolved gases before they can nucleate and form new bubbles.
