Vacuum Distillation (Distillation at Reduced Pressure)

The advanced design of Ayalytical Instruments low pressure vacuum distillation apparatus ensures compliance with ASTM D1160, for determining the distillation characteristics and range of boiling points of various petroleum-based products, biodiesels, and fractions that may decompose if distilled at atmospheric pressure, and that may be vaporized at a maximum liquid temperature of 400C.

The apparatus for reduced pressure distillation is comprised of a 500 ml borosilicate glass flask complete with insulating mantel, a vacuum jacketed distillation column with fused condenser, 200 ml jacket receiver, vacuum distillation apparatus connections, and a cold trap for vapor condensation. The vacuum distillation apparatus features an electric heater with electronic regulator for increased temperature control, a digital temperature indicator for easy readability, a thermocouple sensor for measuring vapor temperature, a vacuum pump, a manostat, a vacuum gage featuring a mercury manometer (mercury not included), and a transfer bath. The reduced pressure distillation apparatus is enclosed in a finished, anodized aluminum structure with PMMA protection for maximum durability.

Ayalytical Instruments offers the vacuum distillation kit as a standard manual model for affordable, small-scale operations, and a semi-automatic model for the convenient, partially-automated testing of larger numbers of samples.
