English: Simple Liebig-type condenser using circulating coolant (shown in aqua), chemical laboratory scale. Derived from, and so near identical in part to, Wikimedia Commons image file Soxhlet extractor.png

Well constructed, accurate earlier image of a research laboratory-scale Liebig condenser with coloring of circulating fluid comparable to other simple condenser images in WP use only existed in a complex apparatus image (of a Soxhlet extractor). The Liebig condenser was extracted from that image to allow more general use of the nice quality partial image. Hence, this image should be considered a redacted version of the important earlier effort of User:Quantockgoblin.
