A reagent vessel, an apparatus and a method for manufacturing a lower part of a reagent vessel for an analytical instrument are disclosed. The reagent vessel is configured to store a liquid reagent. The reagent vessel comprises a cover and a lower part. The lower part comprises a bottom wall, a front wall, a rear wall, two opposing side walls and at least one connection wall. The cover, bottom wall, front wall, rear wall and two opposing side walls define at least one internal volume for storing at least one liquid reagent. The two opposing side walls are at least partially connected to one another by the at least one connection wall located within the at least one internal volume. The connection wall is spaced apart from the bottom wall. The connection wall and at least the two opposing side walls can be injection-molded and are monolithically formed.

A tool for fabricating a control surface is disclosed. In various embodiments, the tool includes a first block defining a longitudinal direction running between a leading edge end and a trailing edge end; a first sidewall spaced a first lateral distance from the first block to form a first closeout channel running in the longitudinal direction between the first block and the first sidewall; and a second sidewall configured to form a second closeout channel running in the longitudinal direction, the second closeout channel disposed laterally opposite the tool from the first closeout channel.

A molded article has an exterior surface, a non-exterior surface, and a projecting or recessed portion provided on at least one of the exterior surface and the non-exterior surface. A repeated pattern of projections and/or recesses or a texture face, which serves to disturb the flow of resin, is provided on the non-exterior surface.

An injection molding machine system includes an injection molding machine, a mold, heater device, and a pressing device. The mold includes a fixed side mold and a slide mold. When the slide mold is clamped at a first mold clamping position, one primary molding cavity is formed by a slide side recessed portion, and one primary molding cavity is formed by a fixed side recessed portion. A pair of primary molded articles, are molded by injection molding. The mold is opened, and bonding end surfaces of the primary molded article remaining in the slide side recessed portion and the primary molded article remaining in the fixed side recessed portion are melted by the heating device. When the slide mold is clamped at a second mold clamping position, a secondary molding cavity is formed by the slide side recessed portion and the fixed side recessed portion. When the pressing device is driven, the primary molded article in the slide side recessed portion is pressed against the primary molded article in the fixed side recessed portion and the bonding end surfaces are fused together. In other words, a molded article is obtained.

A monolithic control surface includes an upper shell portion, a lower shell portion, a stringer connected to the upper shell portion and the lower shell portion, a trailing edge end, and a solid trailing edge region connected to the upper shell portion, the lower shell portion and the stringer.

A thermally conductive microplate made of thermoplastic material, comprising a microplate body (150) having at least 96 wells (151) arranged in the microplate body (150), the microplate body (150) having a flat microplate bottom (154), and each well (151) having at least one well wall (152) and a planar well bottom (153) which is aligned with a well bottom plane (200) shared by all well bottoms (153) and has a bottom thickness of at most 1000 m. Also disclosed is a method for producing the thermally conductive microplates. The microplate body (150) is preferably arranged in a frame carrier (300), in particular is welded, adhesively bonded or riveted thereto. Having high thermal conductivity, upright-format thermally conductive microplates are optimised for automated processing in analysis and synthesis methods that are temperature sensitive and based on temperature change.

An aerator mixing rod includes a body having a first and second opposite ends and an outer surface extending between the ends. The body defines a longitudinal axis extending through the ends. The aerator mixing rod also includes teeth extending radially outward from the outer surface, with a first row of teeth and a second row of teeth spaced from the first row along the longitudinal axis. A first passageway is formed between adjacent teeth of the first row, and a second passageway is formed between adjacent teeth of the second row. The first passageway is at least partially misaligned with the second passageway in a direction parallel to the longitudinal axis such that the first passageway and the second passageway form a tortuous path for fluid flowing along the outer surface of the body. The aerator mixing rod is formed from an injection-moldable material by an injection molding process.

An aerator mixing rod includes a body having a first end, a second end opposite the first end, an outer surface, and a plurality of teeth extending radially outward from the outer surface. The teeth include a first row of teeth and a second row of teeth spaced from the first row of teeth along a longitudinal axis of the body. A first passageway is formed between adjacent teeth of the first row of teeth, and a second passageway is formed between adjacent teeth of the second row of teeth. The first passageway is at least partially misaligned with the second passageway in a direction parallel to the longitudinal axis to at least partially form a tortuous path for fluid flowing along the outer surface of the body.
