English: Friedrichs condenser, chemical laboratory scale

Available Wikimedia Commons image of a research laboratory-scale Friedrichs condenser, from User:Smokefoot, was edited to add standard circulating coolant color, and to make ground joints and hose connections to match those of side-by-side appearing condensers (this detail based on the important earlier effort of User:YassineMrabet on that image), and mirrored for ports to point in a uniform direct, and then cleaned up to remove stray background "noise" (pixels). This image should considered a schematic relative of all other Friedrichs columns appearing at Wikimedia Commons.

Note there are misspellings of this condenser name in Wikimedia Commons (name properly bears an "s"), and there are coil-design cold finger condensers labeled incorrectly as Friedrichs (where the defining characteristic is the molded spiral-walled glass core, tight-fitting to the outer walls of the condenser.
