Abstract
Abstract A multistation, single-channel photometric solution analyzer having a rotor adapted to carry a plurality of removable cuvettes in the form of rigid, hollow, elongated bodies exteriorly engaged by a flange seating against an axially extending surface of the rotor. The cuvettes may be affixed to a flexible belt to facilitate transport, installation, and removal of cuvettes as a group.
