摘要:
The invention relates to a device for electrical disintegration of cell aggregates, with an electrode unit which has an electrode head and an electrode body, and with a chamber which has an inlet for receiving fluid containing cell aggregates and which has an outlet for discharging the fluid, wherein the chamber has a wall and the electrode body is arranged inside the chamber and is electrically insulated from the wall. According to the invention, the wall has a plurality of electrically conductive portions which are spaced apart from one another and which are arranged in such a way that, when an electrical voltage is applied between the electrode body and the wall, a plurality of active fields can be generated.

A method, composition and structure to treat fouling. In one embodiment, the method of treating fouling includes providing a structure including a first component of a base material and a second component of an energetically activated nanostructure, and applying a stimuli to the structure that effectuates an increase or decrease in the temperature of the energetically activated nanostructure. The increase or decrease in the temperature of the energetically activated nanostructure modifies the chemical and/or mechanical properties of the base material. The modifications to the chemical and/or mechanical properties of the base material obstruct fouling of the structure.

A system for sterilizing or microbially deactivating instruments and devices. The system includes a circulation system for circulating a microbial deactivation fluid through a chamber for containing the instruments and devices. The chamber forms a portion of the circulation system. The system further includes a fluid over-flow/make-up air assembly. The fluid over-flow/make-up air assembly includes a manifold having an inner cavity that is in fluid communication with the circulation system, an overflow port in the manifold, and an overflow valve assembly disposed in the manifold allowing fluid flow from the cavity to the overflow port when a pressure in the cavity exceeds a pressure in the overflow port by a predetermined amount. A filter assembly is attached to the manifold. The filter assembly has a filter valve assembly in communication with the cavity. The filter assembly is operable to allow air through the filter assembly into the cavity when the pressure within the cavity is a predetermined amount less than the pressure within the filter assembly.
