[Bacteriological and technical testing of an 0.2-micrometer air-eliminating infusion filter (author's transl)].

The elimination of bacteria from an i.v. solution and the flow rate of different solutions were tested using an 0.2 micrometer Pall Ultipor Filter. The filtration under the influence of gravity as well as under the increased trans-filter pressure was able to eliminate microbial contamination completely. In a second test an interdependence between viscosity and the flow rate of solutions could be shown.
