Brief introduction: LS from LB film technology, membrane technology and LB films are similar in technology. LB film can be defined as a layer or multilayer film from liquid surface accumulation on a solid substrate, through molecular density at a constant flow of single molecule layer dipping into the matrix. In other words, the film is formed by one or more Langmuir membrane accumulation to a solid surface, from the gas phase into the liquid phase, through the vertical dip on the solid substrate (or vice versa). Get a wide range of the arrangement of the membrane, the from single layer thin to hundreds of layers of multilayer structure. Irving Langmuir and Katherine Ms. Blodgett found LB films in the early 20th century science. LS membrane and LB films are very similar, the only difference is the LS membrane membrane is horizontal, not vertical membrane. Features: 1. The 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 sensors), test data precision, good repeatability; 3. All Chinese operating software based on Windows WINDOW, 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. Draw 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. Constant tension can be set, sliding barrier during tensile membrane move to maintain constant tension. 9. Tensile membrane speed is adjustable.
