What is a Vacuum Filter Used For?
"Vacuum filter" is a term quite familiar to those in the analytical field: biological analysis, radiological fraction analysis, or for purifying organic, corrosive liquids like solvents (mobile phase) in HPLC analysis.
We can see that many filtering devices, in general, and vacuum filters (vacuum filtration devices) in particular, are widely used in industry. These filtering devices are used to separate heterogeneous mixtures through a filter, where the residue is retained on the filter while the solution passes through the filter under pressure relative to the pressure below the barrier.
To Understand Vacuum Filtration, We Need to Understand What a Vacuum Environment Is:
Vacuum: In classical theory, a vacuum is a space that contains no matter. Thus, a vacuum has non-zero volume and zero mass (and thus zero energy). Because there is no matter inside, a vacuum is an environment with no pressure.
So, vacuum filtration is the process of separating heterogeneous mixtures in a suspension under a vacuum environment.
