Pneumatic NMR tube spinner

This takes standard 5 mm NMR tubes and spins them using a lab compressed air supply. The rotation may not be particularly smooth, although this can probably be improved on if the inside of the pneumatic spinner and tube holder are polished smooth.

This was used extensively for infrared photochemistry work where the spinning sample was irradiated with an infrared source (see video below). Spinning the sample causes mixing and ensures the entire sample volume receives appro
