The trap also prevents contamination of the facilities’ vacuum system in the event the supernatant floods the vacuum flask.

Subject: [DCHAS-L] vacuum filtration safety
Are there any safety consideration in using vacuum filtration (side-arm vacuum filtration Erlenmeyer flask with adaptor and Buchner funnel using the building vacuum line) without a trap? Or is the trap's only purpose to collect back-flow from a water aspirator?
