Abstract: A core rod assembly (10) for blow molding includes a core rod head (16), a first fluid pathway (A1) extending along a first length of the core rod head (16), and a second fluid pathway (A2) extending along a second length of the core rod head (16). The first and second fluid pathways (A1, A2) may be fluidly isolated from each other and provide selective temperature control of respective first and second portions of the core rod assembly (10) during the blow molding process. At least a portion of the first fluid pathway (A1) may be longitudinally offset from the second fluid pathway (A2) so as to define respective first and second temperature zones (zone 1, zone 2) along the respective first and second portions of the core rod assembly (10).

Abstract: A capillary transfer pipette includes a draw tube having a distal end defining a draw tube opening through which liquid is drawn via capillary action, a proximal end, and a lumen. A squeeze bulb is arranged proximally of the draw tube and defines a fluid chamber in fluid communication with the lumen, the squeeze bulb being compressible to dispense drawn liquid from the draw tube. An air vent hole is formed in at least one of the draw tube or the squeeze bulb, and is configured to vent air to facilitate drawing of liquid through the draw tube opening via capillary action. A volume indicating element may be provided on the draw tube, and the air vent hole may be located proximally of the volume indicating element. The lumen may be formed with a first diameter at the proximal end and a differing second diameter at the distal end. Methods of collecting liquid with, and of making, a capillary transfer pipette are also disclosed.

Abstract: A closure (10, 100, 150) for a labware device (20). The labware device (20) defines an interior chamber (25) having at least one opening (92). The closure (10, 100, 150) includes a closure body (12, 102) configured to be mounted to the labware device (20) and in fluid communication with the opening (92). A vent valve (14, 122) is mounted for movement relative to the closure body (12, 102). The vent valve (14, 122), with the closure body (12, 102), defines a space (72, 120) that defines a path between the closure body (12, 102) and the vent valve (14, 122) for gas exchange between the interior chamber (25) and the exterior of the labware device (20). A filter (50) is positioned within the space (72, 120) and is configured to filter contaminants from gas entering the interior chamber (25) via the path.

Abstract: Described are pipettes capable of dispensing both high volumes of liquid and highly accurate smaller volumes of liquid wherein the accuracy of the volume of liquid delivered increases along the length of the pipette. Embodiments of the pipette include an elongated body with an outer surface, an inner surface defining a lumen within the elongated body, a proximal orifice at a proximal end, a distal orifice at a distal end. The intermediate portion includes a first generally frustoconical-shaped portion defined by a first inner diameter proximate the proximal end of the elongated body and a second inner diameter proximate a second end thereof. In an embodiment, the intermediate portion includes a second generally frustoconical-shaped portion defined by a third inner diameter proximate the transition to the first portion and a fourth inner diameter adjacent the distal end of the elongated body.

Abstract: A cell culture device (10) of the cultivation of cells. The cell culture device (10) includes a plurality of trays (12a, 12b, 12c, 12d), each tray (12a, 12b, 12c, 12d) having a cell growth surface (20) and at least one wall (22, 24) extending upwardly from the cell growth surface (20). The at least one wall (22, 24) is configured to receive an additional tray thereon. A ratio of the number of the plurality of trays (12a, 12b, 12c, 12d) per a height dimension of the plurality of trays (12a, 12b, 12c, 12d) is greater than or equal to about 1 tray per 12 mm.

Abstract: A container for a flexible bag of liquid that supports the bag during transportation, storage and use in dispensing of the liquid. The container is made from two generally similar pans that form lower and upper parts of the container. Each pan includes a plurality of generally similar multiple projections that function to support the container on a surface as well as in a stable stacked formation.

Abstract: A surface supporting growth of cells in culture, the surface prepare to provide hydrophilic moieties exposed thereon for enhancing the attachment of biological materials. The surface contains the hydrophilic moiety as part of an amphipathic molecule also having a hydrophobic region that is anchored or embedded within a polymer substrate, and oriented such that the hydrophilic moieties are exposed on the outer surface of the substrate. In one embodiment the surface is customized to provide qualitative and quantitative moieties to enhance particular cell growth. In one embodiment, the surface is provided on a culture apparatus such as a dish or plate.

Abstract: In one embodiment, a personal hydration system includes a fluid reservoir having first and second spaced apart apertures. A first port is coupled to the first aperture, and a second port is coupled to the second aperture. A flexible tube has a first end that is coupled to the second port for communication with an interior of the fluid reservoir. The personal hydration system further includes a handle having a first end coupled to the first port, and a second end coupled to the second port. A channel near the second end of the handle extends over at least a portion of the first end of the tube and thereby captures the first end of the tube between the channel and the fluid reservoir.

Abstract: A closure for attachment to a centrifuge bottle. The closure comprises an end wall and a sidewall extending from the end wall. The sidewall comprises a first terminal end, a second terminal end, a first transition surface, and a second transition surface. The first terminal end has a first outer peripheral boundary at a first radial distance from an axial centerline. The second terminal end has a second outer peripheral boundary at a second radial distance from the axial centerline. The second radial distance is less than the first radial distance. The first transition surface extends between the first outer peripheral boundary and the second transition surface. The second transition surface extends between the first transition surface and the second outer peripheral boundary.
