Abstract: A gasket assembly and methods of construction and assembly thereof are provided. The gasket assembly includes an elastically deformable, resilient carrier layer having an upper surface and a lower surface extending in planar, generally parallel relation with one another between an inner periphery and an outer periphery when in a disassembled state. At least one top layer is fixed to the upper surface proximate at least one of the inner periphery and the outer periphery. At least one bottom layer is fixed to the lower surface in radially spaced relation from the at least one top layer. The upper surface and the lower surface take on a non-planar, spring-biased shape upon compressing the gasket assembly between a pair of surfaces to an assembled state.

Abstract: A compact chromatographic device and use thereof are disclosed. The device permits trapping of a first analyte while permitting passage of other analytes, followed by trapping of a second and subsequent analytes in an orderly series. Each analyte is trapped sequentially by a different chromatographic media. The process allows detection and/or measurement of each analyte without interference from other analytes previously trapped, enabling assays of analytes in a compact device without elution of analytes from the device. The compact device is pre-assembled and ready to use in a point of care or non-laboratory setting.

Abstract: A testing cartridge for metering of a sample to be tested. The testing cartridge includes a casing defining a casing opening and a sliding member defining a sliding member opening. The casing opening or the sliding member opening can define a specified volume, wherein the casing opening and the sliding member opening collectively define a sample application region dimensioned to accommodate receiving an amount of sample exceeding the specified volume. The sliding member is movable transversely to the casing opening by having the sliding member and the casing traverse across each other's respective openings to remove excess sample from the received amount of sample and retain the specified volume from the received amount of sample.

Abstract: A cut resistant chemical handling glove that is flexible and lightweight comprises a cured, liquid-impervious polymeric latex shell. A tacky acrylic adhesive with low shear strength can be used. A cut resistant liner is slipped on the tacky adhesive coating and is infiltrated with a polymeric latex coating and cured to integrally attach the cut resistant liner with the cured polymeric coating. When the latex glove is worn on a hand and a cutting edge, such as a knife edge, contacts the glove, a crease is formed due to slip at the tacky adhesive-cut resistant liner interface creating a geometry that reduces cut stress intensity at the knife-edge thereby increasing the cut resistance of the glove. Processes for making and using these gloves are also described.

Abstract: A damage tolerant cut resistant chemical handling glove that is flexible and lightweight comprises a cured, liquid-impervious polymeric latex shell, a knitted cut resistant liner comprising a cotton yarn and at least one cut resistant yarn, the liner being infiltrated with a soft nitrile or polyurethane layer such that the liner bonds to the shell. The soft nitrile or polyurethane layer seals interstices of the cut resistant liner and replicates its rough texture on the external surface of the glove, providing enhanced grip properties. A thin nitrile latex layer applied to and cured together with the polyurethane layer to protect the polyurethane layer from oil or chemical degradation. The intimate seal thus created between the shell and the liner prevents accumulation of liquid there between, which prevents formation of a liquid boundary layer and interference with grip properties of the glove.
