Why Filter Flasks Are Built With a Heavy Wall
A filter flask holds a partial vacuum while a funnel or Buchner filter draws liquid through it, so its wall has to resist the pressure differential without cracking — this is why filter flasks are made with a noticeably heavier wall than a standard conical flask. The side-arm's 1/2-inch barb gives a secure push-fit connection to vacuum tubing, and the 1L, 2L and 5L range covers routine lab-scale filtration up to larger batch volumes.
