Dissolution Vessel, 1000ml, 7000-G,Hanson Research

DISSOLUTION VESSELS symmetry and dimensional attributes with respect of USP and the manufacturer centering specifications are key for a proper system suitability qualification. Axis: datum line describing the ideal center of revolution of the inner cylindrical surface of the vessel. Cylinder inner diameter: measurement across the cylindrical portion of the vessel and through the axis. Cylinder circularity: a condition of the inner surface of the vessel cylinder where all points of the surface that are intersected by a plane perpendicular to the vessel axis are equidistant from the axis. Cylindricity: a condition of the inner surface of the vessel cylinder in which any point of the surface is equidistant from the axis . Perpendicularity: angular relationship between the plane containing the points on the lower surface of the vessel support flange and the axis. Center: datum point describing the center of revolution of the inner spherical surface of the vessel. Spherical radius: distance from the points on the inner surface of the spherical portion of the vessel to the center. Circularity of the hemisphere: a condition of the inner surface of the spherical portion of the vessel where all points of the surface intersected by any plane containing the center are equidistant from the center. Concentricity between center of the hemisphere and the axis of the cylinder: a condition where the center lies on the axis. Flatness of bottom surface of flange: a condition of the bottom surface of the flange where all of the points lie in a plane relative to each other. Do remember that not all vessels fit all centering manufacturing specifications
