It supports vacuum mode operation and works with interchangeable optional column types. Optional DAQ software enables measurement and calculation of results.
The Batch Distillation Column Apparatus OperatiX – 04 separates liquid mixtures comprised of distinct liquids that are soluble in one another via distillation. This Batch Distillation Column Apparatus is fed with a recommended ethanol and water mixture, which partially evaporates as it heats on the way to the bottom of the column. It supports batch rectification with different types of columns available as optional.
Product Overview
Liquid mixtures comprised of distinct liquids that are soluble in one another are separated via distillation. Distillation in a counterflow is referred to as rectification.
The recommended liquid mixture for our distillation column system is ethanol and water. The column is fed with it. On the way to the bottom of the column, when it is heated to boiling, it partially evaporates. The created mixed vapour then ascends the column. The component with the lower boiling point is concentrated more in the combined vapour (ethanol). A condenser and a phase separation tank are used to condense it once it exits the top of the column. The remainder of this condensate is fed back into the column while a portion is collected in a tank as a product.
It continues to heat up and interchange materials with the rising mixed vapour here as it descends. As a result of this exchange, the liquid phase gains more water and the vapour phase gains more ethanol. Two tanks can be used to collect the liquid phase, which settles to the bottom.
There are different columns available as optional for this Batch Distillation Column Apparatus. Sensitive values are measured, displayed, and other parts, including temperatures, can be controlled by moving the temperature controller to the top or bottom of the column.
Optionally sensor data can be transferred to the computer for processing if desired. Additionally, the optional software enables recording and saving data on a PC via USB/LAN. The comprehensive course materials outline the foundations and offer a step-by-step overview of the experiments.

Construction and Design
The Batch Distillation Column Apparatus OperatiX – 04 is built around an electrically heated evaporator with infinitely varied power. A feed pump delivers flow at a maximum rate of 400mL/min at variable speed. Feed, boiler, top product, and phase separation tanks are made of glass and stainless steel, with capacities of approximately 10L, 7L, 5L, and 0.5L respectively. A coiled condenser cools the product, while a separate coiled condenser and phase separation tank condense the top product. Rotameters measure flow at the top product condenser and product cooler, each ranged 1 to 7lpm. Reflux ratio is adjusted using valves. A vacuum pump enables vacuum mode operation, reaching a final vacuum of 200mbar. Different temperature sensors are fitted per column, and a pressure gauge measures the vacuum in the system.
