15′ roll of pure copper mesh packing. This is used for increasing the surface area of the inside of your reflux column and boosting ABV. Highly recommended for use with any reflux column. Also great for removing sulphides when using a stainless steel column.
Mesh is 5″ wide. It comes tightly wound in a roll. Unroll and rewind backwards to a medium tight roll with a diameter slightly larger than the inner diameter of your column so that it fits snug.
Clean with diluted vinegar and salt mixture after each run and before using for the first time.
