Title: Steven Kreuzer and His Sterility-Testing Invention.

Introduction

Steven Kreuzer is an inventor associated with Lowell, Massachusetts, and Rapid Micro Biosystems, Inc. His patent work addresses a practical challenge in membrane-filtration sterility testing: controlling how pressurized samples enter a testing cassette.

Latest Patents

Kreuzer is associated with 1 patent, titled “Splashguard and Cassette Assembly for Sterility Testing.” Membrane filtration introduces a sample into a sterile environment, such as a cassette, through an inlet port and passes it through one or more filters. When samples are pumped in at high pressure, they may spray, mist, or foam, potentially producing inconsistent results and obscuring the view through the cassette lid.

The invention describes a splash guard designed to transition incoming sample fluid from high pressure to a lower-pressure flow. This helps the fluid enter the cassette more smoothly, supporting more consistent results and clearer observation of the incubated media.

Career Highlights

Kreuzer’s documented patent contribution focuses on improving the handling of samples during sterility testing. His work connects fluid-flow design with the practical needs of accurate testing and visual analysis.

Collaborations

Kreuzer is associated with Rapid Micro Biosystems, Inc. His listed coworkers include Hunter Black and David Lefort.

Conclusion

Steven Kreuzer’s patent describes a splash guard and cassette assembly intended to reduce disruptive fluid behavior during membrane-filtration sterility testing, helping support more reliable results and clearer analysis.
