Abstract:
The present invention relates to a filter device having a housing, having at least two flow chambers separated from one another by membranes, having at least one connection for each flow chamber, and having at least one filter cap which is put on in the end region of the housing and is connected directly or indirectly thereto. Tolerance variations which frequently occur during the installation of the filter device are avoided according to the present invention in that all connections for the flow chambers are positioned on the housing. The present invention also relates to a housing of a filter device having at least two flow chambers separated from one another by membranes and having at least one end region which is connected to one of the flow chambers and is closable by a filter cap which may be put on the housing. Each of the flow chambers has at least one connection and all connections for the flow chambers are positioned on the housing.
Abstract:
A plasma concentrator for producing plasma concentrate from a plasma from which erythrocytes have been substantially removed. The device comprises a concentrating chamber having an inlet port and an concentrate outlet, the concentrating chamber containing hydrogel beads and at least one inert agitator; and a concentrate chamber having an inlet communicating with the concentrator outlet through a filter, and having an plasma concentrate outlet port. A process for producing plasma concentrate from plasma from which erythrocytes have been substantially removed, comprising the steps of a) moving the plasma into a concentrating chamber containing hydrogel beads and an agitator to form a hydrogel bead-plasma mixture; b) causing the agitator to stir the hydrogel bead-plasma mixture, facilitating absorption of water by the beads from the plasma, until a hydrogel bead-plasma concentrate is formed; and c) separating the plasma concentrate from the hydrogel beads by passing the plasma concentrate through a filter. The concentrator can be one or more syringe devices coupled for multiple concentrations.
Abstract:
A filtering device for filtering out of leukocytes from blood, blood plasma, blood components or protein solutions has a non-woven fabric, and at least one membrane having a thickness of smaller than 150 nullm and a pore size smaller than 15 nullm.
Abstract:
Phase inversion microporous membranes including at least two different pore size regions are provided, wherein two membrane sheets are placed, back-to-back, such that the qualifying pore zones are positioned internally within the structure. Exemplary membranes according to the present disclosure provide excellent thermal stability and retention characteristics. Methods for fabricating and using the disclosed membrane structures are also provided according to the present disclosure.
Abstract:
The present invention is directed to a filtration system including filter media that use diffusion as a method of particulate reduction that balances the contact time required for a desirable level of interception and filter performance. The filter system of the present invention includes a filter medium that removes particulate contaminants by diffusion, means for providing sufficient contact time for an influent to contact the filter medium such that the filter medium can intercept sub-micron particulates at an average flow rate below that of an on-demand or instantaneous flow rate; and a storage buffer for providing a filtered effluent at a rate independent of the average flow rate required to achieve adequate particulate reduction through the filter medium.
Abstract:
An apparatus and method for filtering particles from a fluid comprises a fluid inlet, a fluid outlet, a variable size passage between the fluid inlet and the fluid outlet, and means for adjusting the size of the variable size passage for filtering the particles from the fluid. An inlet fluid flow stream is introduced to a fixture with a variable size passage. The size of the variable size passage is set so that the fluid passes through the variable size passage but the particles do not pass through the variable size passage.
Abstract:
There are Two Basic Components 1. An outer bag providing a strong and stable container plus the final screen for any escaped sludge particles. 2. Two inner bags which have the ability to expand and contract, thus retaining and separating solids while permitting liquids, free of solid, to easily pass through to the other bags without restrictions. None of the bags are capable of entrapping free liquid. After a while the entrapped solids presents a barrier to the free liquid but constant pressure of 1 to 5 bars continues to push the free liquid out of the inner and outer bags. Design: A critical point in design is to make the bags large enough so that they are capable of one continuous pumping cycle example: 8 hours, 12 hours, 24 hoursnullso they can accommodate various flow rates and different percentages of solids (and sizes) of solids.
Abstract:
This product will be made of polyurethane. The purpose of this product is to minimize accidental burns and spill overs. With it's unique clamp down feature, this product will do just that. Made dishwasher safe it allows a steril cleaning. This product also allows a person to use both hands, control tipovers and attaches safely to the sink.
Abstract:
A filter element (10) having a supporting body (11) around which a filter medium (12) is wound. The filter medium (12) is a weldable material and is sealingly affixed to the supporting body (11) two radial weld seams (18) and/or a longitudinal weld seam (19). The welding of the filter medium (12) onto the supporting body (11) eliminates the need to produce prefabricated tubes of filter medium, and enables the filter medium to be processed directly from a roll.
