Fine Particle Extraction from Solvent

<< < (2/2)

billnotgatez:
I sort of feel like a dummy.
Why rotovap when you can just centrifuge.

 I would , as the OP suggested, combine the crystalbond + dust mixture with the solvent
let the  crystalbond dissolve
centrifuge and carefully pour off the solvent leaving the dust in the bottom of the vile
put more solvent in and mix
centrifuge again and carefully pour  ​off the solvent leaving the dust in the bottom of the vile again
repeat maybe 3 times
after the last pouring let the remaining solvent evaporate

this might wash away the crystalbond leaving just the dust.

Babcock_Hall:
I like the centrifugation idea, and I should have thought of it.  If plastic tubes are not suitable, Corex tubes are a special kind of glass centrifuge tube that can be spun at higher RCF than other glass centrifuge tubes.
