What is the approximate vacuum pressure used in the procedure?

The task is about choosing the right suction level for a vacuum step in the procedure. A moderate vacuum of roughly 30 mm Hg provides the needed driving force to pull liquids through the filtration or to draw moisture off without being too aggressive. This keeps the process efficient while avoiding problems like boiling or loss of volatile components that can happen with stronger vacuums. If the vacuum were much stronger (much lower absolute pressure), you risk rapid, uncontrolled flow and potential damage to the sample or filter; if it were weaker (higher absolute pressure, closer to atmospheric), the filtration would proceed too slowly or not at all. So, about 30 mm Hg is the practical balance for this step.
