    Abstract: A rapid one-pass liquid filtration system efficiently concentrates biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. Additional concentration stages may be added in “cascade” fashion, in order to concentrate particles below the size cut of each preceding stage remaining in the separated fluid in a concentrated sample suspension. This process can also be used to create a “band-pass” concentration for concentration of a particular target size particle within a narrow range.

    Abstract: Highly efficient and rapid filtration-based concentration devices, systems and methods are disclosed with sample fluidic lines and a filter packaged in a disposable tip which concentrate biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. The concentrate is then dispensed from the disposable tip in a set volume of elution fluid. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. All conduits by which the disposable tip attaches to the instrument are combined into a single connection point on the upper end of the tip.

    Abstract: The present disclosure provides devices, systems and methods for concentrating a fluid sample. A portable or hand-held concentrator is used to draw the fluid sample through a filter into an internal chamber, capturing target particles on the filter. An elution cartridge containing an elution fluid is used to recover the captured particles into a reduced fluid volume. The hand-held concentrator includes a tip, which, when opened, allows the hand-held concentrator to draw the fluid sample into the tip and through the filter wall into the internal chamber. The drawing occurs due to a vacuum or wicking source in the internal chamber of the hand-held concentrator. The target particles are captured on the filter. The elution fluid contains a foaming agent and is held under a head pressure of gas soluble in the elution fluid. The target particles are eluted from the filter into the reduced fluid volume using an elution foam that is formed when the elution fluid is released from the elution cartridge. Embodiments of the hand-held concentrator are entirely self-contained and can operate without electrical power.
