Start from a ready-made setup — distillation with or without a Vigreux column, under vacuum, reflux, a Dean–Stark trap, Soxhlet extraction, a Schlenk line, vacuum filtration — or fit single pieces: round-bottom flasks, condensers, distillation heads, adapters, funnels, thermometers and stoppers. Every piece is drawn at its true size and fits only at a ground joint of its own taper.
Hold the apparatus with clamps on a stand, heat it on a hot plate or a mantle, pipe cooling water and gas through tubing, and watch the liquids fill, boil and condense. Save the apparatus as an SVG that opens again here, or put it in a drawing on draw.cheminfo.org, where it is scaled as one picture.
Fit flasks, condensers, heads and adapters at their true ground joints, pipe water and gas through them, and save the apparatus as an SVG. The builder needs JavaScript, because the apparatus is assembled in your browser.
