Brief introduction JML04C series multi-function LB film analyzer (LA / Mo Tianping) is a precision measuring instrument for measuring the physical and chemical properties of polar organic compounds (two). Dynamic study of various polar organic substances (proteins, lipids, polymers, etc.) of single molecular layer of surface film, recording film of molecular surface area (a) and surface tension (R) or surface pressure (PI) between the function relation, the famous biological membrane lipid bilayer structure hypothesis and lung may be the existence of a surfactant, confirmed this view with the film balance technique. In recent years, film balance in the field of biomedical application is becoming more and more widely, especially in the analysis of pulmonary surfactant and neonatal respiratory distress syndrome, adult respiratory distress syndrome (ARDS) and other diseases of the lungs and achieved remarkable results. The occurrence and application of exogenous pulmonary surfactant successfully for the treatment of RDS (distress syndrome), monitoring the RDS in the extraction and separation or artificial synthesis of pulmonary surfactant in the process or clinical and film balance is of surfactant surface characteristics will be a lot of testing. In the fields of chemical, biological membrane, liposome, integrated optics, nonlinear physics, optics, LB film, and other fields are widely used in the application of chemical, biological membrane, integrated optics, nonlinear physics, optical and electronic science. Features 1, the operation process and data collection by PC computer and the front single chip microcomputer control, realizes the automation and the intelligent, the human error may fall to the lowest; 2, key parts (including sensor) import, test data accurate, good repeatability; 3, based on the WINDOW window of the whole Chinese operation software, user interface is friendly, graphics can be stored print, data can be processed two times; 4 tank, large surface area, high sensitivity, small leakage; 5, can automatically measure the liquid surface tension. 6, can draw r-A and PI -A curve. 7, according to r-A and PI -A curve made into a film tension limit, repeated compression and expansion of barrier film. 8, can set a constant tension, sliding in the film when the film is moved to maintain a constant tension. 9, pull film speed can be adjusted. 10, considerate design to ensure that the instrument can be applied to the conventional test environment, and the general configuration of PC online work, running smoothly, small vibration, noise; Technical parameter 1 surface tension measurement range: 0mN/m ~ 150mN/m 2 resolution: < 0.05 mN/m 3 detection method: TYPE WILHELMY 4 tank: LANGMUIR 5 tank area: 300mm * 200mm (model: JML04C3) 300mm * 100mm (model: JML04C2) 200mm * 80mm (model: JML04C1) The other tank area can be customized 6 compression area: 90% 7 double sliding barrier: double sliding barrier technology, small noise, small vibration, low leakage, high sensitivity 8 sliding speed: 0.48 ~ 97mm/min 9 film speed: 0.22 ~ 45mm/min 10 pull film mode: uplink, downlink 11 power supply voltage: AC220 + 10V 12 power frequency: 50Hz 13 maximum power consumption: < 150W 14 working temperature: room temperature, can be outside the constant temperature water tank 15 working humidity: 30% to 85% relative humidity
