Brief introduction: JML04 LB film multi-functional film machine is determination of polar organic physical and chemical properties of precision measuring instruments. It can dynamically study various organic polar substance (protein, lipid, polymer, etc.) of the surface of the monolayer film, the record of membrane molecular surface area (A) and (r) or surface tension function relation between the surface pressure (PI). In recent years, the balance in the field of biology, medicine, water treatment increasingly extensive application, especially in the analysis of the water of organic matter in water treatment, extraction and artificial lung surface active material, research on neonatal respiratory distress syndrome and the relationship between the adult respiratory distress syndrome and other lung diseases, has made remarkable achievements. In addition, the membrane balance measurement technology in the application of chemical, biological membrane, liposomes, nonlinear physics, optoelectronics, integrated optics, dilute the active source, LB film, supramolecular configurations, and other fields have a wide range of USES. Features: 1, operation process and data acquisition by PC computer and front single-chip microcomputer control, automation and intelligent, may make the artificial operation error to a minimum; 2, key parts and components (including sensor), the test data is accurate, the repeatability is good; 3, all Chinese operating software based on Windows WINDOW, user friendly interface, graphics printing, can store data can be secondary processing; 4, liquid tank surface area, high sensitivity, small leakage; 5, can automatically measure the liquid surface tension. 6, can draw the r - A and PI - A curve. 7, according to the r - A and PI - A set made membrane tension on the lower limit curve, sliding compression and expansion into A film. 8 and constant tension can be set, sliding barrier during tensile membrane move to maintain constant tension. 9, la film speed is adjustable. Technical indicators: Surface tension measurement range: 0 mn/m - 150 mn/m Resolution: 0.05 mN/m Detection methods: hanging piece (WILHELMY TYPE) Mode of liquid trough: LANGMUIR Liquid tank material: all four fluorine material The compression area: 90% Sliding speed: 0.48-97 - mm/min Film speed: 0.22-45 mm/min Tensile membrane model: upward and downward Power supply voltage: AC220 plus or minus 10 v Power frequency: 50 hz
