A sample vessel for holding a sample for analysis by a sample analyzer, the sample vessel comprising: a body that includes a bottom, an open top spaced from the bottom along a first axis, a side wall that extends from the open top to the bottom, and an interior chamber for holding a sample and that extends from the open top toward the bottom along the first axis, the body including an opaque portion, a first translucent portion, and a second translucent portion spaced from the first translucent portion a distance that extends along a second axis that is perpendicular to the first axis and that forms an optical axis, the first and second translucent portions (104, 106) each disposed along the bottom of the body, wherein the body includes an opaque body component that defines the opaque portion, a first translucent component that defines the first translucent portion and a second translucent component that defines the second translucent portion, wherein the sample vessel is an injection molded part with multiple components that define the opaque portion and translucent portions (104,106), wherein the opaque component comprises a first polymeric material, and the first and second translucent components and each comprise a second polymeric material that is different from the first polymeric material, wherein the second polymeric material is selected from the group consisting of a cyclic olefin copolymer, acrylic, acrylic copolymer, polystyrene, polycarbonate, polyetheramide, and other translucent polymeric materials, and copolymers thereof, and wherein the sample vessel includes a predominant amount of the opaque portion relative to the first and second translucent portions (104, 106). a body that includes a bottom, an open top spaced from the bottom along a first axis, a side wall that extends from the open top to the bottom, and an interior chamber for holding a sample and that extends from the open top toward the bottom along the first axis, the body including an opaque portion, a first translucent portion, and a second translucent portion spaced from the first translucent portion a distance that extends along a second axis that is perpendicular to the first axis and that forms an optical axis, the first and second translucent portions (104, 106) each disposed along the bottom of the body, wherein the body includes an opaque body component that defines the opaque portion, a first translucent component that defines the first translucent portion and a second translucent component that defines the second translucent portion, wherein the sample vessel is an injection molded part with multiple components that define the opaque portion and translucent portions (104,106), wherein the opaque component comprises a first polymeric material, and the first and second translucent components and each comprise a second polymeric material that is different from the first polymeric material, wherein the second polymeric material is selected from the group consisting of a cyclic olefin copolymer, acrylic, acrylic copolymer, polystyrene, polycarbonate, polyetheramide, and other translucent polymeric materials, and copolymers thereof, and wherein the sample vessel includes a predominant amount of the opaque portion relative to the first and second translucent portions (104, 106).
