Multiple identification point automated parameter assurance method
Systems and methods provide automated parameter assurance features and results for consumables used in bioprocessing and particularly for purifying, filtering, harvesting and collecting bioprocessing fluids. Consumables having these features are sized, shaped, configured and constructed to interface with and be a component of such a bioprocessing system that includes a multi-use component or device with which it operatively engages such as by docking, engagement with a connector or other approach that allows for insertion and removal of the consumable. The consumable may be a component having a single-use life or a limited life. Each consumable has a median by which information, which can include use limits and specifications, is associated with that specific consumable, and those limits and specifications are communicated to the multi-use component which indicates any inappropriateness for use with the multi-use component.
AUTOMATED MODULAR FILTRATION SYSTEM
An automated modular filtration system, particularly for low volume tangential flow filtration processes, comprises a plurality of filtration modules formed as separate assemblies and at least one control unit for jointly controlling filtration processes of individual filtration units. Each filtration module contains at least one individual filtration unit for executing a filtration process independent of the other filtration units, first input ports for receiving a first type of fluids, second input ports for receiving a second type of fluids, and exit ports for outputting unused system fluids. First type fluids are process fluids are specific to the filtration processes executed in individual filtration units. Second type fluids are system fluids not specific to filtration processes executed in the individual filtration units. The second input and exit ports establish inter-module connections so system fluids can be forwarded from one filtration module to an adjacent filtration module of the filtration system.

AFFINITY CHROMATOGRAPHY DEVICES CONTAINING A HEAT TREATED FIBRILLATED POLYMER MEMBRANE AND MANIFOLDS CONTAINING THE SAME
Affinity chromatography devices that include a fibrillated heat treated polymer membrane that contains inorganic particles having a spherical shape and a particle size distribution that has a D90/D10 less than or equal to 3 are disclosed. A blend or combination of spherical inorganic particles having a nominal particle size from about 5 microns to about 20 microns may be utilized. Also, the devices have a hydraulic permeability from about 200(10.sup.12 cm.sup.2) to about 700(10.sup.12 cm.sup.2). The affinity chromatography devices have a dynamic binding capacity (DBC) greater than 35 mg/ml at 10% breakthrough at a residence time of 20 seconds. Additionally, the affinity chromatography devices have a cycling durability of at least 100 cycles without exceeding an operating pressure of 0.3 MPa. Manifolds containing multiple affinity chromatography devices and manifolds in a parallel configuration are also disclosed.
Filter device, and method of assembly
A filter device includes an inlet manifold, an outlet manifold and membrane filter units. Each membrane filter unit has an inlet opening for a fluid flow to be processed, a first outlet opening for a retentate portion of the fluid flow, and a second outlet opening for a remaining portion of the fluid flow. Each inlet opening is fluidly connected to the inlet manifold, and each first outlet opening is fluidly connected to the outlet manifold. The two membrane filter units are staggered and are not axially aligned with respect to each other. One of the membrane filter units is fluidly connected to the inlet manifold and to the outlet manifold via a first set of conduits, and the other membrane filter unit is fluidly connected to the inlet manifold and to the outlet manifold via a second set of conduits.
Hemofilter for in vivo blood filtration
Hemofilters for in vivo filtration of blood are disclosed. The hemofilters disclosed herein provide an optimal flow of blood through the filtration channels while maintaining a pressure gradient across the filtration channel walls to enhance filtration and minimize turbulence and stagnation of blood in the hemofilter.
Parallel processing reverse osmosis water filtration systems
Parallel processing reverse osmosis water filtration systems using multiple RO (reverse osmosis) filter systems having their raw water input connections coupled together, their product water output connections coupled together and their drain connections coupled together. Using appropriate valving, any one or more reverse osmosis filter systems may be decoupled from the rest of the system for servicing without shutting down the entire system, and one or more additional reverse osmosis filter systems may be added to increase the product water output capacity when needed. Optional features disclosed include enhanced product water storage capacity, control of the total dissolved solids in the product water dispensed, and protection against leaks that may disable one RO filter system, but not the entire parallel processing reverse osmosis water filtration systems. Various embodiments are disclosed.
FILTER CASSETTE ARTICLE, AND FILTER COMPRISING SAME
A filtration cassette including a multilaminate array of sheets including filter sheets alternating with permeate sheet members and retentate sheet members, and a cross-flow filter device comprising a multiplicity of stacked filtration cassettes of such type. The improvements associated with the filtration cassettes described herein include, but are not limited to, at least one of: reinforced inlet(s) providing for longevity and improved cleanability of the cassettes; spacer permeate screens to limit throughput restriction; stainless steel or otherwise stiffened permeate sheets to prevent movement and increase flux; and stainless steel permeate sheets that can be used with ultrasonic transmission to minimize fouling of the filter sheets and extend cleaning cycles. Advantageously, the filtration cassettes are more resistant to higher temperatures than the filtration cassettes of the prior art.
