RTD-2010 real-time constant temperature degassing instrument
Introduction: RTD-2010 real-time constant temperature degassing instrument is a new upgraded product, which can effectively remove all kinds of gas in the dissolution medium, and the removal rate is as high as 85%. By outputting high-quality dissolution media, the accuracy of liquid phase test results is guaranteed. Its technical level is currently leading at home and abroad, with a wide range of applications and can be used in conjunction with drug dissolution systems. working principle With the use of a large number of hollow fibers inside the degassing membrane, water molecules cannot pass through such small holes, but gas molecules can pass through. When working, the dissolution medium passes through the inside of the hollow fiber under a certain pressure, and the outside of the hollow fiber is continuously pumped away by the vacuum pump, and a certain negative pressure is formed, so that the gas in the water will continue to pass through the water. The hollow fiber overflows outward, and then the dissolution medium passes through the heating pipe for heating treatment, and finally achieves the purpose of removing air. Features: 1. Meet the standards Meet the standards for the preparation of dissolution media in the Chinese Pharmacopoeia 2. Record function Log record, with audit trail function 3. Human-computer interaction Color page touch screen, clear parameters at a glance, quick and convenient operation 4. Hydraulic detection is equipped with hydraulic detection, which can realize automatic switching between self-priming and external pressure 5. High efficiency The three methods of heating, vacuum and circulation are combined into one, making degassing more thorough and rapid 6. High precision. Automatically complete quantitative liquid feeding, preheating, degassing and quantitative liquid discharging, and the accuracy of single liquid discharge can reach ±1% 7. A wide range of applications It can directly treat solvents, pure water, distilled water, etc. commonly used in dissolution experiments, which is more efficient than traditional methods and has a wide range of applications. technical parameter: Model: RTD-2010 Heating range: room temperature -45.0℃ (maximum heating temperature difference 15℃) Temperature resolution: 0.1℃ Temperature control accuracy: ±2℃ Volume resolution: 0.1mL Volume accuracy: ≤±1% Removal rate: ≥85% Degassing membrane pore size: 300μm OD/220μm ID Degassing membrane area: 0.58m² ID Hollow fiber membrane count: 7400 Porosity: 40%Porosity Silk film material: Polyurethane Degassing rate: ≤1000mL/Min Vacuum resolution: 0.1KPa Vacuum degree: ≤-95KPa Target oxygen content: ≤2.8mh/L log record function, audit trail Input power: 220Vac±10% 1100W Machine size: 260x530x560mm Whole machine weight: 23Kg EMC: IEC6100-4-2, IEC6100-4-4, IEC6100-4-5, IEC6100-4-11 Working temperature: (5~40) ℃ Storage temperature: (-20~60) ℃ Working humidity: (20~80)% RH Storage humidity: (5~95)% RH
