Re: Question About Packing a Column
- Here is how to pack a column with either S/S or copper pot scrubbers.
I can't take credit for this - the advice comes from Dr. John Stone
in instructions which came with his apparently no longer available
Pot scrubbers are commonly sold in a package of three fairly large
scrubbers. This is exactly the correct amount to pack a column 1.5"
in diameter and 30" long.
Gently tease each scrubber along the natural way it is woven into a
long oval which can then be cut into three equal size pieces (you now
have nine "mini" pot scrubbers). Some advice - don't use your wife's
good sewing scissors to do this.
Now gently stretch each of these nine pieces into an oval three
inches long and soak them in a gentle soap solution. Insert them into
your column using a broom handle to *gently" pack them together. The
nine pieces will be exactly right for a 30" column.
Thoroughly flush your column with warm water to remove any trace of
soap before peforming a distillation (duh!).
Hope this helps.
