As already mentioned here I ordered me column packing from a polish manufacturer. But I will probably extend my order for a bigger amount.
I would offer to share this and calculated that I could send 1 liter, whats about 880 grams of the packings, to anybody in the world who wants to - as
a letter.
The rings would be about 17€ ($22), pack and send would be about 9€ ($12).
If somebody is interested PM me.
Thats what we are talking about, size is actually 4,2mm x 4,2mm, surface area will be about 1800m2/m3.
Material is ANSI 304 stainless steel - thats not resistant against concentrated strong acids just to make this clear.
The actual beauty is that one can use them in a long Hempel column under vacuum without suffering much loss of pressure, getting good separation
nevertheless. Beats Raschigs by a factor of about 8 at STP, under vacuum Raschigs are not good at all.
This makes many separations by vacuumdistillation possible using just the column - no head and backflow-divider. Fractionation is enough, no
rectefication needed.
Thats a lot easier an quicker so.
