Brief introduction: JML04 LB FILM multi-function pull FILM machine (also called FILM FILM scales BALNCE) will be to determine polarity organic matter (amphiphilic molecule) 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 and surface tension (r) (A) or the function relationship between the surface pressure (PI), the famous biological membrane lipid bilayer structure hypothesis and the lungs there may be A surface active substance theory, are confirmed by membrane technology scales. Balance in recent years, membrane application in the field of biology, medicine, water treatment has become increasingly widespread. In addition, the membrane balance measurement technology in the application of chemical, biological membrane, liposomes, nonlinear physics, optoelectronics, integrated optics, dilute active source, LB film, supramolecular configurations, and other fields have a wide range of USES. Features: 1. The operation process and data acquisition control controlled by PC computer and front; 2. Test data precision, good repeatability; 3. User friendly interface, graphics printing, can store data can be secondary processing; 4. Liquid trough large surface area, high sensitivity, small leakage; 5. Can be automatically measuring the liquid surface tension; 6. Can map r - A curve; 7. Can be set according to the r - A curve made membrane tension on the lower limit, sliding barrier repeated compression and expansion into membrane; 8. Constant tension can be set, sliding barrier during tensile membrane mobile in order to maintain a constant tension; 9. Tensile membrane speed is adjustable; Technical indicators: 1. Surface tension measurement range: 0 mm/m ~ 150 cows/m mn/m (0 ~ 150 mn/m) 2. Resolution: < 0.05 mm/m cattle (0.05 mN/m) 3. The detection methods: hanging piece (WILHELMY TYPE) 4.
