A novel type of high efficiency, high speed, laboratory still has been developed for obtaining distillation curves on small (5 ml) samples of high boiling (300°F+) materials. The apparatus is simple consisting essentially of a hollow, baffled, horizontal metal bar heated at one end by means of an electrical cartridge heater. In operation, the feed sample is placed in one end of the still, the heater and a vacuum pump turned on, and distillation fractions collected at the other end. Conventional distillation curves are obtained directly.
