Copper Spiral Prismatic Packing

Spiral Prismatic Packing is used in a column to increase the surface area of the refluxed liquid alcohol moving down the column to allow greater mixing of alcohol vapor from below. This helps compress and separate the fractions. It will allow for better collection of hearts. Normally used for production of vodka or neutrals. Commonly referred to as SPP.
