The technology disclosed herein relates to a vent assembly having a vent housing that defines a first airflow pathway, a second airflow pathway, and a third airflow pathway. The first airflow pathway is configured for fluid communication with an interior of an enclosure. The second airflow pathway is configured for fluid communication with the external environment, and the third airflow pathway extends between the first airflow pathway and the second airflow pathway. A membrane is coupled to the vent housing such that the second airflow pathway and the third airflow pathway are in communication through the membrane. Coalescing filter media is disposed within the vent housing such that the third airflow pathway and the first airflow pathway are in communication through the coalescing filter media. The vent assembly defines a spacing region between the coalescing media and the membrane.

Disclosed herein are articles and methods for blood separation. For example, inventive articles and methods that remove red blood cells from blood samples are described.

An inline filter housing with a biodegradable, hydrophilic material that operates in conjunction with a field sampling apparatus to both concentrate field sampled environmental DNA particles from water samples and to automatically preserve the captured DNA via desiccation, thus avoiding filter membrane transfer steps, chemicals or cold storage preservation requirements. The hydrophilic filter housing is capable of rapidly preserving the field sampled environmental DNA captured on the filter membrane at ambient field temperatures.

Filter holders and membranes are provided that can be included within a bioreactor bag system. The filter holders and membranes include features that abut the bottom of the filter membrane and prevent or reduce sagging of the porous filter region during use.

Filter holders and membranes are provided that can be included within a bioreactor bag system. The filter holders and membranes include features that allow incorporation of advanced membrane materials having differing material characteristics than traditional membranes that more closely matched the characteristics of the filter holder.

The invention concerns a filtration assembly (1) for microbiological testing and a method of using the filtration assembly for that purpose. The filtration assembly (1) comprises a ring-like membrane support (10) holding a filtration membrane (11), a cylindrical reservoir (20) of which opposite axial ends have openings and one axial opening is removably and fluid-tightly attachable to the membrane support (10) to define a sample volume adjacent to the filtration membrane (11) on one axial side of the membrane support (10); and a drain member (30) removably and fluid tightly attachable to the membrane support (10) to define a drain channel space adjacent to the filtration membrane (11) on an opposite axial side of the membrane support (10).

Filter holders and membranes are provided that can be included within a bioreactor bag system. The filter holders and membranes include features that allow incorporation of advanced membrane materials having differing material characteristics than traditional membranes that more closely matched the characteristics of the filter holder.

A consumable device comprising a substantially rigid two-layer main body, window for receiving a membrane, and an electronic tag for storing and communicating information, wherein the consumable device is configured to be received by a molecular filtration device for the purpose of creating a channel within which a solution may be inserted to purify molecules or exchange a buffer solution.

A separation recovery system for separating and recovering an object to be separated includes a metal porous membrane which has a first principal surface and a second principal surface facing the first principal surface and has a plurality of through-holes extending between the first principal surface and the second principal surface, a supply device which supplies a first fluid containing the object to be separated from the first principal surface of the metal porous membrane toward the second principal surface, and a backwash device which supplies a second fluid containing a plurality of particles larger than a size of the plurality of through-holes of the metal porous membrane in a direction from the second principal surface of the metal porous membrane toward the first principal surface.

Devices and methods are provided that permit efficient and selective separation of liquid biological specimens into at least two constituent components to facilitate subsequent quantitative and qualitative analysis on at least one analyte of interest in at least one of the components. The devices generally include one or more sample deposition regions supported on a base. Each sample deposition region includes a separation membrane for separating the liquid biological specimen into two different fractions. The first fraction is trapped by the separation membrane while the second fraction passes through the separation membrane and into a respective collection membrane. The separation and collection membranes are easily separable from the devices and can be utilized for further processing and analysis.
