Analysis instrument having a blow molded reaction chamber

摘要

An analysis instrument is characterized by a rotatable mold ring onto which is drawn superimposed sheets of plastic material. The inner sheet is softened and formed into an indented mold cavity and the outer sheet sealed thereover to define a partially closed sample chamber, or cuvette. A sample to be analyzed is introduced into the chamber. Any of the chambers may have selectively introduced thereinto a suitable reagent and the reaction occurring in any chamber may be selectively monitored at any predetermined circumferential location of the mold ring.
