Centrifuging a Sample  John W. Moore, Jerrold J. Jacobsen, Lois M. Browne, John F. Zimmerman
The demonstration on this page shows a technique that should not be used by undergraduate chemistry laboratory. This video shows what happens to sample in a centrifuge while the centrifuge is on, and the result of stopping the centrifuge improperly. A narrative is included in this video: The centrifuging process allows the solvent to completely settle out. The jarring caused by hand braking destroys the distinct separation between supernatant and solid.

Study of Molecular-Shape Selectivity of Zeolites by Gas Chromatography  Pei-Yu Chao, Yao-Yuan Chuang, Grace Hsiuying Ho, Shiow-Huey Chuang, Tseng-Chang Tsai, Chi-Young Lee, Shang-Tien Tsai, and Jun-Fu Huang
This analytical or physical chemistry sorption experiment uses hexane isomers as probe molecules to demonstrate the "molecular-shape selectivity" behavior of zeolites. Students can also modify the sorption protocol to build their own experiments.

Chromatography, Thin Layer (ChemPages Lab)  John W. Moore, Jerrold J. Jacobsen, Joe L. March
Chromatography, Thin Layer: this is a resource in the collection "ChemPages Laboratory Resources". Thin layer chromatography (TLC) is a method for identifying substances and testing the purity of compounds. TLC is a useful technique because it is relatively quick and requires small quantities of material. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.
