Abstract:
A cell culture apparatus includes one or more plates having a first major surface and an opposing second major surface. The first major surface comprises a structured surface defining a plurality of wells. Each well has an interior surface defining an upper aperture and a nadir, wherein the upper aperture of each well has a diametric dimension in a range from 100 micrometers to 2000 micrometers. The apparatus also includes a plurality of spacers extending from the first major surface along a length of the bottom surface. A plurality of flow channels are defined between adjacent rails.

Abstract:
A method for forming a droplet interface bilayer (DIB) comprises the steps of: (1) providing an assembly that includes a housing contained within an enclosure, wherein the housing includes at least one aperture that comprises a cis portion and a trans portion, at least one cis electrode receptacle and at least one trans electrode receptacle, wherein the cis electrode receptacle is operatively connected to the cis portion, and the trans electrode receptacle is operatively connected to the trans portion; (2) inserting an electrode into each of the cis and trans electrode receptacles; (3) introducing an oil/lipid phase to the enclosure such that the oil/lipid phase flows into the housing through the aperture; (4) delivering at least two aqueous droplets to the oil/lipid phase in such a manner that at least one aqueous droplet is disposed within the cis portion of the aperture and at least one aqueous droplet is disposed within the trans portion of the aperture; and (5) lowering a level of the oil/lipid phase in the cis and trans portions of the aperture to cause the aqueous droplets in the cis and trans portions to expand and move closer to one another until the aqueous droplets contact one another thereby forming the lipid bilayer at the location at which the aqueous droplets contact one another.
Abstract:
A incubator chamber comprises a base, lid and plurality of trays, each of which are stackable upon one another in an open or closed configuration. A clamp could be provided having an interior cavity sized and dimensioned to simultaneously receive a portion of a perimeter of each of a base and a lid.
Abstract:
A device for culturing anaerobic microorganisms is provided. The device comprises a body comprising a waterproof base, a waterproof coversheet attached to the base, and a growth compartment disposed between the base and the coversheet. The growth compartment has a perimeter and an opening that provides liquid access to the growth compartment. A portion of the perimeter is defined by a waterproof seal. The portion includes >50% of the perimeter. A dry cold water-soluble gelling agent is adhered to the base in the growth compartment. A dry first oxygen-scavenging reagent is disposed in the growth compartment.
Abstract:
A tissue engineered model (TEM) structure, an apparatus and method for making a TEM structure, and methods of using a TEM structure are disclosed. In an embodiment, the TEM structure includes at least one TEM segment. Each TEM segment includes a frame defining a bounded area, the frame having a height, a first edge, and a second edge opposite the first edge, each of the first edge and the second edge defining a perimeter of the bounded area, and the height defining a distance between the first edge and the second edge; a membrane affixed to the first edge about a perimeter of the frame; and a solidified gel and cell matrix disposed within the bounded area within the frame, wherein the solidified gel and cell matrix substantially fills a volume defined by the bounded area and the height of the frame.
Abstract:
The invention relates to an air-conditioning space (10) for storing samples in a time-controlled manner, comprising a device (22) for automatically feeding sample containers (18) into a climatically sealed space (12) having at least one wall (43), into which a sample container (18) can be inserted into the climatically sealed space (12) through an opening (40, 42), wherein the feed device (22) has at least one drive and control unit, and an incubator receptacle (30) for receiving the samples (18) is provided inside the climatically sealed space (12). The invention is distinguished by the fact that the feed device has an automatic feed arm (22, 24) which grips a sample container (18) from a receiving position outside the climatically sealed space (12) and deposits the sample container (18) there in a clear deposit position in an incubator receptacle (30).
Abstract:
The present invention discloses a bioartificial liver system comprising a fixed-bed bioreactor packed with gel beads containing hepatocytes of an animal, a plasma reservoir, a plasma separator, and an efflux chamber, wherein the plasma reservoir is located at a position higher than the bioreactor, a ventilation filter in contact with atmosphere is provided at the top of the plasma reservoir, and the top of the plasma reservoir is directly connected to the efflux chamber via a connecting line. The inventive system satisfactorily performs the essential liver functions without the problems of gel bead damage or channeling.
Abstract:
A vermicomposting device for vermicomposting organic material, comprises a casing including an annular hollow body member defining an internal cavity, a head member mounted to an upper end portion of the body member and a base member removably attached to a lower end portion of the body member, and a plurality of composting trays removably disposed within the internal cavity in a stacked relationship. Each of the composting trays is an open top tray including a circular perforated bottom wall surrounded by an annular side wall upwardly extending from the perforated bottom wall. The base member includes a support portion and a drip bucket disposed under the composting trays to receive and collect any liquid byproduct from the vermicomposting process. The head member is movable relative to the body member so as to provide an access to the internal cavity of the body member.
