Linde Type A Zeolite Molecular Sieve

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.

If you prefer a more "chemically correct" version of this structure, the Minit Zeolite A lattice model includes a special 141 degree oxygen atom to create a more accurate cage structure.

Or, have a bit of fun with this model. Instead of the standard bonds, try using our 30mm GlowBonds (or even the 35 or 50mm) & build a "Borg Cube"-hard core Star Trek Next Generation fans only!

Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) atoms & bonds for over 30 years. These parts 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.

Details

The zeolite A chemical formula is Na9[(AlO2)9(-SiO2)15]27H2O and this form is used as a molecular sieve. This molecular is generic in nature as it comes with 3 different pore sizes:

  • 3A: Potassium-exchanged form (K-A), has a pore size of ~3Å, which can separate smaller molecules like water from larger ones like ethylene.
  • 4A Zeolite: Sodium-exchanged form (Na-A), has a pore size of ~4Å, and can adsorb water, ammonia, and smaller hydrocarbons.
  • 5A Zeolite: Calcium-exchanged form (Ca-A), has a pore size of ~5Å, and separate larger molecules such as CO?, propane, and butane.

Zeolites are important in a variety of applications including water softening & catalysis. Read more in our blog: Zeolite Catalyst Molecular Models Teach Oil Cracking
