Batch Cooling Crystallization Apparatus | OperatiX – 02
The Batch Cooling Crystallization Apparatus OperatiX – 02 carries out batch crystallization using a jacketed glass crystallizer with a 1 liter capacity. This Batch Cooling Crystallization Apparatus features a variable speed stirrer, temperature and conductivity sensors, and a sieve set for crystal size analysis. It supports both batch and continuous operation modes. Optional DAQ software enables measurement and calculation of results.
The Batch Cooling Crystallization Apparatus OperatiX – 02 carries out batch crystallization by filling the crystallizer once with solute and solvent to obtain a supersaturated solution and crystals. This Batch Cooling Crystallization Apparatus studies the cooling crystallization process of substances whose solubility varies with temperature. It includes a jacketed glass crystallizer, stirrer, and temperature and conductivity sensors.
Product Overview
The process of crystallization is typically used to clean up substances so that the components of a solution may be separated. To crystallize a solute, a solution must achieve a supersaturated state. A substance, referred to as a solute, must be dissolved in a solution to the point where the solution is unable to dissolve any more solute.
To create a supersaturated solution, one of several techniques can be employed: by evaporation, by cooling, or by adding aggregates. It is a cooling crystallization unit, the Crystallization Unit. As a result, experiments on crystallization can be carried out using constituents whose solubility varies with temperature. The cooling method’s reduced energy costs are one of its key benefits.
A reactor used for crystallization is known as a crystallizer. A crystallizer can be run continuously or in batches. The study of the cooling crystallization process of substances whose solubility varies with temperature is the focus of this section. This Batch Cooling Crystallization Apparatus is designed to carry out batch crystallization, which entails filling the crystallizer once with the solute and solvent before obtaining a supersaturated solution and crystals from it.
A crystallizer, which is essentially a jacketed chemical reactor, is part of this apparatus. The reaction temperature is managed by a bath located outside the crystallizer. A stirrer that is situated on the upper side of the crystallizer stirs the fluid. The temperature of the solution inside the crystallizer can always be determined thanks to a temperature sensor on the upper side of the device. The device also has a conductivity sensor, which can be used to determine the solution’s conductivity as necessary.
Heating is needed to dissolve a higher concentration of solute at high temperatures in order to create the supersaturated solution. Water for the crystallizer’s jacket is supplied by a thermostatic bath. Its control may be carried out using software (optional) or a PID. The crystallization stage begins when a supersaturated solution at a high temperature is attained. Cold or room temperature water is introduced for that function. A pressure regulating valve that maintains the minimum pressure is part of the device. With the filter set included with the machine, a sample of the collected product is examined, which can be used to determine the size of created crystals. Additionally, the device can function as a continuous feeding unit and operate as a continuous crystallization unit.

Construction and Design
The Batch Cooling Crystallization Apparatus OperatiX – 02 is a floor standing unit with castors, built with an anodized aluminum frame and panels made of painted steel. Main metallic elements are made of steel. The crystallizer is a jacketed glass reactor with 1 liter capacity, fitted with temperature sensors and a stirrer for batch operation. A double blade variable speed stirrer, with 2 stirrers rated 0 to 300rpm, agitates the fluid. A feed tank, double jacketed and made of glass, holds 5L. A peristaltic feed pump delivers flow at 0 to 500ml/min with variable speed. K type thermocouples are located at key points of the system. A conductivity cell measures solution conductivity, ranged 0 to 2000μS/cm. Valves allow water circulation according to the process, whether heating or cooling. A set of three sieves, sized 0.5mm, 1mm, and 2mm, supports crystal size analysis. A vessel collects the crystals, and protection devices safeguard the electric circuits.
