Filter Flasks, filtering flasks, vacuum flasks, or Büchner flasks are all common names for this filter flask.
Our Filter Flasks have much heavier walls than a standard conical flasks to endure effects of vacuum filtration
Sidearm extends 1 1/2" with an outside diameter of 1/2" or 3/4" depending on the size, using a barb style connection providing hose flexibility connecting to vacuum source
During filtration, the filtrate enters and is held in the flask while the sample or residue remains on the filter paper in the funnel.
Filter Flasks can also be used as a vacuum trap in a vacuum line.
Filter Flasks are hand produced therefore variations are inherent
