Zeolite Linde A was the first synthetic zeolite to be used commercially. You can clearly see both the alpha & beta cages which makes this model a great teaching tool; only $63.95.
Linde Type A was invented in 1953 by Union Carbide (Linde Air Products was a division of Union Carbide) LTA was originally used as a molecular sieve for the removal of dioxygen impurities from gas streams. The material is still in use industrially today. In the laboratory 5Å, 4Å, and 3Å sieves are used for the removal of organic solvents.
Zeolites are important in a variety of applications including water softening & catalysis. Read more in our blog: Zeolite Catalyst Molecular Models Teach Oil Cracking
