Abstract: A cell culture flask having a flask body that defines a cavity for receiving a cell culture medium is provided. The flask body includes an elongate neck that defines an opening to the cavity, a base, and a sidewall that extends from the elongate neck to the base of the flask body. The sidewall includes a circumferential beveled portion, which may or may not be faceted, that extends from an outermost periphery of the flask body to the base of the flask body at a constant angle relative to a central axis of the flask to define a sidewall angle.

Abstract: A multi-slide assembly includes various components that alone or in combination facilitate testing of test samples with minimal manipulation of assay components. Moreover, the various device components permit centrifugation, culturing and analysis of each test sample to be performed in the same assembly. A frame retains a plurality of reaction vessel assemblies between a pair of opposing channels that are configured to slidably receive the opposing ends of each reaction vessel assembly. A strip cap seals the openings in each reaction vessel using cap members having sealing rings circumscribing the external walls thereof to form compression seals with internal walls of the reaction vessels. Furthermore, in a method of making a multi-well slide assembly, an ultrasonic welding process removably bonds a plurality of wells to a slide plate to provide an adequate seal therebetween during centrifugation, yet still enable separation thereof by an operator.
