Build an Indigo® Zeolite Y molecular model for teaching about water treatment and ion exchange. Learn how its framework enables selective removal of cations, heavy metals, and does water softening, along with classroom and research examples.
Zeolite Y is widely used in water treatment and ion exchange applications due to its uniform pore structure, high cation-exchange capacity, and thermal stability. Its aluminosilicate framework allows selective adsorption of metal cations and other pollutants, making it valuable for softening hard water, removing heavy metals, and purifying industrial effluents. In teaching, Zeolite Y provides a concrete model for demonstrating ion exchange principles and the relationship between framework charge and selectivity. In research and industrial contexts, it exemplifies how nanoporous materials can solve environmental challenges by removing undesired ions from water efficiently and sustainably.
Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years (scroll down to see "Skeletal (Orbit/Minit) and are compatible with every molecular model kit we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.

Really beautiful model! Students have lots of fun and useful discussions while assembling it. Looking at the photographs at the web site was sufficient enough for successful assembly. We are truly satisfied to have this model in our lab.
Visually, this molecular structure of Zeolite Y is beautiful! It received a lot of attention from everyone who passed by it! For the assembly, there is no instruction that comes with the kit and the picture online is the only guide. However, the structure can be made by making 10 sodalite cages and connecting them with bonds via the hexagonal faces (it is helpful to look at the picture while connecting them). Wearing gloves can help provide a better grip while connecting the bonds to the atoms. Overall a good product!
Thanks for the feedback. Trying to describe the assembly was next to impossible so we'll get a picture done of the sodalite cage & add that shortly. Here's a bit more on this model also used for teaching: Zeolite Catalyst Molecular Models Teach Oil Cracking
