Fully automatic solubility tester

1) Product Introduction

SL2100Fully automatic solubility testerBased on the principle of equal volume He He method, we focus on high-precision determination of gas solubility data in liquids, providing key basic data support for the development of new environmentally friendly working fluids, optimization of energy and chemical processes, and design of absorption refrigeration systems.

Equipment operating temperature range covered by country-30~100℃Pressure measurement range0~5 MPa, supporting customized requirements for higher temperature and pressure conditions, with temperature control accuracy of up to±0.05℃The temperature measurement accuracy is better than±0.05℃The pressure measurement accuracy is as high as0.1% FSThe instrument adopts a fully metal sealed structure and a specially designed measurement system to ensure a uniform and stable temperature field inside the balance kettle, maintain the long-term reliability of the system during the testing process, and effectively ensure the reliability and repeatability of the measurement results.

The instrument adopts the classic equal volume saturation method, which calibrates the volume of the gas chamber and the equilibrium kettle system, and directly calculates the solubility based on the pressure changes in the equilibrium state, without the need for complex sampling and analysis processes. Built in adjustable speed magnetic stirring system accelerates the gas-liquid two-phase mass transfer process, shortens the equilibrium time, and improves testing efficiency while ensuring the integrity of the system seal. This method successfully avoids the pressure fluctuations, gas-phase condensation problems that may arise from traditional circulation methods, as well as component disturbances and measurement errors caused by sampling analysis methods.

Equipped with fully automatic measurement and control software, achieving one click operation and intelligent data processing. The software can monitor and record temperature and pressure data in real-time, dynamically determine the equilibrium state, and directly generate temperature solubility or pressure solubility relationship curves. No manual intervention is required throughout the process, greatly reducing the difficulty of operation and further improving the repeatability and reliability of experimental results. The software also has data export function, providing users with a convenient and efficient data processing experience.

SL2100Fully automatic solubility testerWidely applicable, it can meet the solubility testing needs of various gas and liquid systems, especially suitable for high-precision measurement of lubricating oil refrigerants, organic solvent gases and other systems, and performs outstandingly in systems with low solvent saturation vapor pressure. At present, the equipment has been successfully applied in multiple fields such as screening and evaluation of new environmentally friendly refrigeration working fluids, optimization of energy and chemical gas absorption processes, and basic physical property research in academic research institutions.
