Miniaturized devices are designed to obtain a green analytical method using low volume of solvent and consuming less energy power. These devices are easily adapt to be portable which permits in-situ analysis. This study aims to build a photometer and a fluorimeter using 3D printing and low-cost electronic components. The photometer was tested using the iron-phenanthroline complex at concentrations from 0 to 10 mg L-1 in aqueous solution, and also applied to determine methanol in fuel. The fluorimeter was tested using quinine in an aqueous solution with 0.05 mol L-1 of sulfuric acid at concentrations from 0 to 100 mg L-1. In both devices obtained suitable linearity and presented sensitivity higher than previous published papers. The 3D printing provides ease fabrication and manufacture which permits this devices could be designed in accordance to the research application or to the teaching laboratories requirements.
