网页2015年10月2日 · Where a single colony is found, the process has to be repeated, either with a filter of smaller pore size, a dual membrane filter or series filtration. Small wall-less bacteria that can penetrate 0.2µm filters (e.g. Mycoplasma spp ) have been discovered, but are only considered a risk to the safety of those cell culture processes where antibiotics
网页2020年3月3日 · Wetting the membrane is an important first step in preparing your filter. Wetting the membrane pores eliminates dry pathways where contaminants, like particles, gels, or bubbles could pass through, resulting in high defect levels in your process. Polymer membranes are natively hydrophobic or hydrophilic. Hydrophobic – having a natural
网页A Membrane Filter (or “Screen Filter”) performs separations by retaining particles larger than its pore size on the surface of the membrane. Particles with a diameter below the rated pore size may either pass through the membrane or be captured by other mechanisms within the membrane structure.
