Can You Identify This Still? Tou CAN if yOIL re familiar with one of the most promising new unit operations available to chemical engineers. THIS
STILLS
. . . allows you to fractionate many so-called "undistillables." . . . offers you the only known means of distilling many organic substances o f molecular weights over 3 0 0 . . . . allows you to separate many compounds of high-molecular weight without injuring them thermally, . . . gives you an inexpensive method for virtual pilot-plant operations—with a through-put rate o f from 2 to 12 liters of distilland per hour.
The still shown diagrammatically above is one DPPs laboratory Molecular Distillation units—the 14" Centrifugal Molecular Still (Type CMS 14). High-vacuum short path distillation with this still or other DPI laboratory units may open the way for more complete answers to many of your research problems. If you work with petroleum products,
( of
plasticizers, fats o r waxes, synthetic chemicals, essential oils—or- any similar materials—you will find the If Still to be an invaluable aid in your work. Write today for a copy of our new illustrated brochure, c 'Information on High Vacuu m Distillation," giving you detailed information about our many services and unique laboratory aids.
