Abstract: A dialysis device, and a method of dialyzing a sample, are provided. The dialysis device includes a body having a first and a second major side, a first and a second retaining ring disposed on the first and second major sides, and a first and second dialysis membrane disposed, and held between the first and second major sides and the first and second retaining rings. The dialysis device is configured to receive a sample to enable dialysis of the sample across the membranes.

Abstract: An apparatus for agitating materials contained in tubes, including cellular materials and tissues, to release their contents for scientific analysis. The apparatus includes a control enclosure containing a base and a motor, and an interchangeable module that connects to the motor. The interchangeable module includes a tube supporting structure and a rotatable hub connected to one or more strikers positioned to impact the tubes, resulting in agitation of tube contents. Interchangeable modules allow for different shapes and sizes of tubes to be used with a single control enclosure. The apparatus includes a means to measure the rotational velocity of the rotatable hub and the rotational velocity of the strikers. The apparatus further includes protective sleeves for the tubes to prevent breakage, heat build-up from friction and tube caps opening due to rapid impact from strikers.

Abstract: A lock mountable relative to a moveable wing and including an engaging member supported relative to a casing and displaceable to an operative configuration to be cooperable in engagement to restrain the wing in a closed configuration and in which said cooperating configuration the lock presenting a visible interior portion that does not substantially interrupt the form of the wing.

Abstract: A wing including an infill of fixed extent and an outer frame including at least two outer frame member comprises at least one of which includes a pair of associated outer frame portions connected by a telescopic joint comprising a linear joint, said outer frame members connected at a corner joint defined in part by an included angle that may be changed, said the infill bounded by an inner frame having an outwardly disposed peripheral channel supported in relation to the outer frame that at least in part occupies the channel.
