Linde A Synthetic Zeolite Molecular Sieve
SKU: 68794W
Zeolite Linde Type A (LTA) is a synthetic aluminosilicate widely used in ion exchange, adsorption, and catalysis & is noted for its uniform pore size and high thermal stability. Its chemical formula is Na12[Al12Si12O48].27H2O. The framework of this zeolite structure consists of a 1:1 ratio of silicon (Si) and aluminum (Al) atoms with each tetrahedrally coordinated with four oxygen atoms.
For simplicity, this model is built with just black tetrahedral atoms so that the alpha & beta cages are obvious. You can differentiate the Al & Si by substituting with blue, grey, yellow, green or purple colored tetrahedral atoms. Oxygen is left out of the cage structure as there is no suitable geometry for it. The 27 water molecules indicated in the formula are not included.
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) 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.
