Use this Indigo® Zeolite Y molecular for teaching about gas separation and molecular sieving. Learn how pore size and shape enable selective adsorption of CO2, N2, O2, and other gases, with classroom and research examples.
Zeolite Y is a synthetic faujasite that is widely used as a molecular sieve for gas adsorption and separation. Its uniform 12-membered ring pores and high surface area allow it to discriminate between molecules based on size, shape, and polarity. Zeolite Y is an ideal teaching tool for chemistry and chemical engineering students to visualize gas separation principles. Modelling the interactions of O2, N2, CO2, and H2 within the zeolite framework allows students to observe how kinetic diameter, polarity, and diffusion constraints influence adsorption. Zeolite Y serves as a model for environmental and industrial applications, including carbon capture, air purification, and selective gas separation processes and provides a clear connection between molecular structure and real-world functionality.
Indigo Instruments has held inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years (See Skeletal (Orbit/Minit)) that are compatible with every molecular model 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
