Abstract: Membrane filtration is a technique for performing sterility testing on products, in which a sample is introduced to a sterile environment (such as a cassette) through an inlet port and then passed through one or more filters. The samples may be pumped into the cassette at a relatively high pressure, which can cause the sample to spray, mist, or foam. When the sample sprays in this manner, it can cause inconsistent results and can obscure the view through the lid of the cassette, which makes it difficult to analyze the incubated media. Exemplary embodiments provide a unique splash guard sized and shaped to transition the incoming sample fluids from a high-pressure state to a lower pressure flow. Consequently, the fluid flows more smoothly into the cassette which yields more consistent and accurate results.

Abstract: A process for recovering a lipophilic oligosaccharide antibiotic from an aqueous fermentation broth containing the lipophilic oligosaccharide antibiotic admixed with impurities, by-products and/or suspended solids, comprising: a) combining said fermentation broth with an adsorbent; b) adjusting the pH of the broth to alkaline in order to solubilize the antibiotic in the broth; c) allowing sufficient time for the solubilized antibiotic in the alkaline broth to be adsorbed by the adsorbent; d) adjusting the pH of the broth to about neutral in order to stabilize the antibiotic adsorbed on the adsorbent; and e) separating the adsorbent to which the antibiotic is adsorbed from the broth. A medium for storing an oligosaccaride antibiotic comprising an adsorbent having a lipophilic oligosaccaride antibiotic adsorbed thereon is also disclosed.
