Cuvette for projection display of chemical experiments
First Claim
1. A cuvette for demonstrating chemical experiments which comprises an elongated rectanguler parallelopipedal block of transparent material formed unitarily with plane-parallel broad surfaces transluminable for projection display and with parallel upper and lower surfaces, said block being formed between said broad surfaces with a plurality of upright vertically elongated compartments, at least one of which is upwardly open of the shape of chemical experiment vessels, spaced apart in said block, means defining in the material of said block at least one elongate passage communicating between said compartments and terminating in lateral or bottom walls of said compartments at opposite ends at respective ones of said compartments, the walls of said compartments and said passage being defined exclusively by said material unitarily with said block, and means on said block for inducing a chemical reaction in at least one of said compartments, all of said compartments opening at said upper surface.

Abstract
A cuvette for the projection display of chemical experiments comprises a rectangular parallelopipedal block of transparent material, e.g. glass or a transparent synthetic resin, which is formed with one or more compartments having the shapes of chemical experiment vessels and in requisite passages communicating therewith so that complete chemical experiments can be carried out within the vessels and demonstrated by projection display.
