What is the difference between vacuum filtration and ...

Vacuum filtration is faster than gravity filtration, because the solvent or solution and air is forced through the filter paper by the application of reduced pressure. Do not use vacuum filtration to filter a solid from a liquid if it is the liquid that you want, and if the liquid is low boiling.

Standard Operating Procedure (SOP)

When centrifuging hazardous chemicals, use the centrifuge in a fume hood or glovebox. If the centrifuge cannot be used in a fume hood, the centrifuge tubes should have airtight caps and only be filled/opened in the fume hood. Always use safety centrifuge cups to contain any potential spills and prevent aerosols.
