Abstract: The present disclosure relates to a low friction bearing liner for a solenoid that may include a core layer, a first outer layer overlying a first surface of the core layer, a second outer layer overlying the first outer layer, a first inner layer overlying a second surface of the core layer that is opposite of the first surface of the core layer, and a second inner layer overlying the first inner layer. The first outer layer and the first inner layer may include a fluoropolymer material and may have a melt flow rate of at least about 2 g/10 min at 372° C. The second outer layer and the second inner layer may include a fluoropolymer material distinct from the fluoropolymer material of the first outer layer and may have a surface coefficient of friction of not greater than about 0.2.

Abstract: An adhesive may include an adhesive structure and an adhesive composition. The adhesive structure may include a graft copolymer. The adhesive composition may include at least about 1 wt. % and not greater than 40 wt. % of a macromonomer component for a total weight of the adhesive composition, at least about 50 wt. % and not greater than about 98 wt. % of a (meth)acrylic based polymeric component A for a total weight of the adhesive composition, and at least about 0.1 wt. % and not greater than about 30 wt. % of a tackifier component for a total weight of the adhesive composition. The macromonomer component may have a weight-average molecular weight of at least 1000 g/mol and a glass transition temperature (Tg) of at least about 40° C. The (meth)acrylic based polymeric component A may have a glass transition temperature (Tg) of not greater than about 20° C.

Abstract: Disclosed is a disposable needle filter apparatus with a universal truncated syringe-receiving neck to enable the filtration of fluids/solutions aspirated into a needle-bearing syringe. The apparatus includes a needle seal stopper and needle stop to create a substantially airtight chamber to facilitate fluid aspiration through an enclosed filter and into the syringe. In an alternative embodiment, the filter apparatus includes an extended syringe-receiving neck configured to receive a specifically sized syringe/needle combination. In a further embodiment, the receiving neck is constructed as a modular unit to allow for interchangeable necks to accommodate different needle and syringe sizes with different cross-sectional diameters. In a yet further embodiment, the neck is constructed with stepped tapered segments of serially larger cross-sectional diameters to accommodate differently sized syringes. In a still further embodiment, the apparatus includes an accessory needle secured to the apparatus inlet.

Abstract: A bio-reactive container and filter assembly to improve flow rates and mass transfer without increased pressure. An inlet filter membrane secured to the container defines a container chamber in combination with the container. An inlet filter membrane element may also be secured to the container to provide structural support to the membrane. An outlet membrane secured to the container defines a container chamber in combination with the container. An outlet filter membrane element may also be secured to the container to provide structural support to the outlet membrane. Inlet and/or outlet filters and/or filter elements are constructed to significantly increase surface area available for fluid and/or gas ingress and/or egress. Single and double layer membranes with mixtures of hydrophobic and hydrophilic characteristics are used to maximize perfusion and gasification/degasification of bio-reactive containers.
