What is the first step to take when setting up glassware for a vacuum filtration?

When setting up glassware for a vacuum filtration, the first step should be to inspect the tubing for any holes or damage. This is crucial because the effectiveness of the vacuum filtration relies on an airtight seal throughout the system. If there are any defects in the tubing, it could lead to reduced vacuum pressure, which would compromise the filtration process.

Ensuring that the tubing is functional and free from leaks helps to establish the necessary conditions for successful filtration. Once it has been confirmed that the tubing is in good condition, the next steps can involve connecting the vacuum source and positioning the filter funnel, but these should follow the initial inspection to guarantee overall system integrity.
