The setup affords a significant amount of space (~1/2 fume hood) and therefore should be place on one side of the fume hood and not in the middle. These columns have different surface areas and numbers of theoretical plates, and thus differ in their ability to separate close-boiling components. The vapor is then cooled as it goes through the inner tube of the condenser. Dependable -80C storage with a focus on sustainability without sacrificing sample protection. A simple distillation is incapable of significant purification if the boiling points of the components are too close. Increase your throughput and gain more insight while saving costs and time.

Every vaporization-condensation event (called a "theoretical plate") is similar to a simple distillation, and each event enriches the distillate in the lower boiling component. The setup affords a significant amount of space (~1/2 fume hood) and therefore should be place on one side of the fume hood and not in the middle. SYNC101075: joint: ST/NS 14/20, L 75 . Several columns are shown in Figure 5.39: a) Vigreux column with glass indentations, b) Steel wool column made simply be loosely inserting steel wool into the cavity of a fractionating column (similar to a West condenser, but wider), c) Glass beads filled in the cavity of a fractionating column. The bulb of the thermometer should be just below the level of the side arm. A \(50\%\)/\(50\%\) mixture of two components whose boiling points differ by only \(20\)-\(30^\text{o} \text{C}\) would require at least three theoretical plates to obtain a distillate with \(> 95\%\) purity.
