Latest Patents

Marie Pressel's latest patents include the **Sample Preparation Unit** and **Process for Treatment of Residual Nucleic Acids Present on the Surface of Laboratory Consumables**.

The **Sample Preparation Unit** is designed primarily for sterility testing. It features a housing body comprising at least two ports that serve as fluid inlets and/or outlets. The unit includes a membrane support and a lid section that creates a membrane chamber adjacent to the membrane support. One of the ports facilitates fluid transfer from a first volume within the membrane chamber, situated upstream of the membrane, while the other port allows fluid transfer to a second volume downstream of the membrane. Additionally, a movable part on the housing body enables selective interruption or establishment of fluid transfer between the ports and the membrane chamber.

Her second patent focuses on a **Process for Treatment of Residual Nucleic Acids**, which contains two phases: first, treating with ethylene oxide in a gaseous state, and second, treating the surface with hydrogen peroxide in either liquid or gaseous form. The outcome of this innovative method prevents the amplification of residual nucleic acids, significantly enhancing the accuracy of PCR or TMA reactions in laboratory settings.
