Multi functional phase balancerIt is an effective analytical tool for determining the solubility parameters of compounds and mixtures in subcritical and supercritical fluids. Researchers can directly or observe phase changes under accurately controlled conditions, and experiments can be conducted in liquids, supercritical carbon dioxide, or other liquefied gases.
In addition, this instrument can also be used to study the effect of co solvents on the solubility of compounds in supercritical fluids. Researchers can observe the decomposition, precipitation, and crystallization processes of compounds over a wide range of pressures and temperatures.
It is useful for determining process parameters of supercritical fluids, such as the crystallization and reaction of substances in supercritical fluids. For example, it can be used to determine the solubility of reactants and products, providing a basis for operating supercritical reactions, and can also be used for small-scale batch supercritical reactions.
Other applications include determining the cloud point of polymers and their solubility in supercritical carbon dioxide and other liquefied gases. More complex applications include determining process parameters for injecting new materials into swelling polymers and conducting surface deposition experiments.
Main components:
The multifunctional phase balancer mainly consists of the following parts: a visual variable volume phase kettle, a constant temperature oil bath box, a liquid pump, an injection refrigeration system, a carbon dioxide injection pump, a preheating and temperature control system, a computer-controlled acquisition system, a safety and explosion-proof system, an electrical control system, and a box support.
Multi functional phase balancerThe main body is made of 3I6L to ensure the corrosion resistance of the kettle body and the safety of high-pressure experiments. The front and rear visual windows are made of high-pressure quartz glass. There is a freely movable piston in the balance kettle, which can automatically control the pressure and volume of the experimental system in front of the piston by pressing the medium into the kettle cavity behind the piston. Piston adjustment is both flexible and convenient, while avoiding balance disruption caused by changes in system pressure during the sampling process. The kettle chamber is designed as a slender tube, and with the assistance of a precise distance measurement system, accurate changes in volume can be inferred, thereby obtaining accurate phase density and molar volume data on the basis of easily measurable mass.
