English: Simple Snyder column/air condenser, chemical laboratory scale.
Available image of a research laboratory-scale Snyder column (a type of air condenser) was edited to make ground joints match those of side-by-side appearing Vigreux column (this detail based on the important earlier effort of User:YassineMrabet on that image), and then cleaned up to remove stray background "noise" (pixels). This image should considered a schematic relative of all other Snyder columns appearing at Wikimedia Commons.
