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 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. 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 and identify. A single-use pipette tip includes fluid ports for aspirating the sample and connecting to a concentrating unit.
