Glass Fractionating Column (also called a fractional column), designed to be filled with packing material.

These are essential pieces of equipment to separate your mixtures into component parts (or fractions, the columns namesake). The greater surface area on the rising column separates out the fractions based on differences in volatilities.

This each cycle of vapor, condensing and vaporizing, through a fractionating column, vapors are enriched with a constituent components. Larger surface areas, or longer columns, allow for more cycles improving separation.

Packable columns work by having a non reactive, porous material packed inside such as glass beads or metal pieces such as Raschig rings, creating a vast amount of surface area for this cycle to occur. This grants a greater surface area for the ascending vapor to meet the descending liquid allowing for multiple condensations and distillations within the column.

Fractionating columns are used in both small benchtop laboratories, and large, industrial scale ones. Heat entering a fractionating column is a critical component for the successful use of this device, and much be controlled accurately, we highly recommend using a 2 necked flask with a thermometer inlet to monitor temperature.

A heating mantle is also recommended for achieving a quality distillation. Excess or insufficient heat can lead to flooding, foaming or an unsuccessful distillation.

Fractionating Column Specifications:

– Made of Borosilicate glass
– 24/29 ground glass joint
– Coiled drip style bottom preventing packing material dropping out, and giving a runoff for distillate.

Packing material sold separately.
