Highly toxic, as most heavy metals.
But metallic uranium is pretty safe.

even the biggest prep columns for lab use have about 20-40 gram (Total) loading...


ever run a mol scale reaction in a 20 liter reactor with one of those fat spinning blade stirrers that sit in a greased neck?


ever run a flash column with a "donkey cock" column?

pretty sure its called simulated moving bed and moving bed...

not countercurrent...

>> No.1938021

>>1935774


I had that happen a couple times....


also that is exactly what the plates look like from a Porphyrrin column.


and in the end, after running the column 4 times successively...

you get 9% yield (theoretical is something like 15% though)

also, the pimp shit:


vacuum oven. put the whole tray of test tubes in there...


turn it on, come back, and have like 1 mL in each one

shits pimp. we had all buchi oil-less vacuum pumps with digital vacuum controllers in our lab.
