Abstract. We describe a small-scale, reusable, and low-cost double-diffusion setup that allows microscopic observation over time for use in mineral precipitation experiments that use organic polymers as a matrix. The setup uniquely accommodates changes in solution chemistry during the course of an experiment and facilitates easy harvesting of the precipitates for subsequent analysis.

Short summary
In the course of experiments exploring the formation of calcium phosphate minerals in a polymeric matrix, we developed a small-scale, reusable, and low-cost setup that allows microscopic observation over time for use in mineral precipitation experiments that use organic polymers as a matrix. The setup uniquely accommodates changes in solution chemistry during the course of an experiment and facilitates easy harvesting of the precipitates for subsequent analysis.
