摘要： A micro fluid filtration system (100) preferably for increasing the concentration of components contained in a fluid sample has a fluid circuitry (1). The fluid circuitry (1) comprises the following elements: A tangential flow filtration element (7) capable for separating the fluid sample into a retentate stream and a permeate stream upon passage of the fluid, an element for pumping (3) for creating and driving a fluid flow through the fluid circuitry (1) and at least one element for obtaining information about the properties of the fluid sample within the circuitry. The circuitry further comprises a plurality of conduits (24) connecting the elements of the fluid circuitry (1) through which a fluid stream of the fluid sample is conducted. The circuitry (1) has a minimal working volume of at most 5 ml, which is the minimal fluid volume retained in the elements and the conduits (24) of the circuitry (1) such that the fluid can be recirculated in the circuitry (1) without pumping air through the circuitry (1). An integrated microfluidic element (20) of the circuitry (1) contains the functionality of at least two elements of the group of elements of the circuitry (1).

摘要： A flow filtration system (1) for concentration of components contained in a fluid sample comprises a fluid channel (2) being formed by two conduits (4, 5) allowing a bidirectional flow of the fluid sample through the fluid channel (2), a tangential flow filtration module (3) and at least two pairs (8, 9) of piston pumps (6) each having two piston pumps (6), wherein the piston pumps (6) having a piston swept volume forming a reservoir being able to contain the fluid for volumes of up to 100 ml. The tangential flow filtration module (3) is located in the fluid channel (2) so that a fluid flowing through the channel (2) passes through the filtration module (3). At each end (10, 11) of the channel (2) one piston pump (6) of each pair (8, 9) of piston pumps (6) is located in such a manner that the piston pumps are fluidically connected in parallel. The system (1) is arranged and adapted such that during the concentration process at least for a predetermined period of time only one of the pairs (8, 9) of piston pumps (6) is used to drive the fluid through the tangential flow filtration module (3).

摘要： A micro flow filtration system comprises a fluid circuitry (3) and a first reservoir (1) outside the circuitry (3) suitable for containing a fluid. The fluid circuitry (3) comprises a tangential flow filtration module (10) capable of separating the fluid sample into a retentate stream and a permeate stream upon passage of the fluid sample into the tangential flow filtration module (10) through an inlet feed (18). The fluid circuitry (3) further comprises a second reservoir (2) integrated in the fluid circuitry (3), a pump (5) for creating and driving a fluid flow, optionally at least one pressure sensor (6, 7 or 8) for acquiring and detecting data about the fluid sample, optionally a pressure regulator (9) for regulating the flow in the fluid circuitry (3) and a plurality of conduits (22) forming the fluid circuitry (3) together with the second reservoir (2), the TFF-module (10), the pump (5), the pressure sensor (6, 7 or 8) (if present) and the pressure regulator (9) (if present). The volume of the first reservoir (1) outside the circuitry (3) is significantly larger than the volume of the second reservoir (2). The first reservoir (1) outside the fluid circuitry (3) is connected to the circuitry (3) via a connection conduit (31) such that the fluid flows unidirectionally into the circuitry (3) until the first reservoir (1) is empty so that a continuous fluid flow from the first reservoir (1) to the circuitry (3) is established.
