Latest Patents

Mrozinski is credited with 1 patent, titled “Apparatus for Mixing Liquids Used in Countercurrent Multiphase Liquid Separation.” The invention presents a reusable apparatus for multiphase, multistage countercurrent liquid separation. It is particularly suited to progressively separating target microorganisms from background organisms and materials while enabling precise transfer, air exclusion, homogeneous mixing, and isolation from the ambient atmosphere. The design operates without valves and is intended to be low-cost.

The apparatus includes at least one chamber with a piston-like sliding bottom that moves or is braked while maintaining a seal. Internal mixing is provided, preferably by a magnetic stainless-steel ball that can be reciprocated from outside the chamber. Stops limit the bottom’s movement, and the patent describes several ways to actuate the apparatus.
