<p>A unitary, one-piece, plurality of intermediate (throw-away) dilution cups for the turntable transport (T) on a spectrophotometer analyzer (S). The cups (18) are moulded together, side-by-side, in a circular arc, preferably five cups per arc, in a one-piece, multi-cup unit. Each one-piece arc unit of five cups may be detachably secured to the radially outer row of reaction cups on the transport (T) by means of a pair of spaced radial arms (22,24) extending radially outward from the outer side of the five cup arc unit, such arms (22,24) being positionable in the space (28,29) between adjacent reaction cups. Formed on the outer end of each arm (22,24) is a vertical rod (32,34) of larger width than the space between the reaction cups, thus enabling the arc unit of five dilution cups to be detachable "hooked on" to the reaction cups. Each dilution cup is formed of highly polished materials and each cup has a concave floor thus ensuring positive central bottom positioning of a minute quantity of fluid therein to achieve complete mixing of the dispensed fluids. A novel configuration of the reaction cup (180) itself is also disclosed.</p> |
