LB membrane analyzerIt is an instrument device used to study the relationship between the surface area of a film spread on a liquid surface and surface pressure, and is widely used in the deposition field of LB films.
The working principle of LB membrane analyzer:
Single molecular layer formation: A single molecular layer (called Langmuir film) formed by functional molecules, nanoparticles, nanowires, or particles that are insoluble at the gas-liquid or liquid-liquid interface has fluidity and can move freely at the interface.
Membrane compression and deposition: By controlling the packing density of these molecules, LB films with specific properties can be prepared. The LB film analyzer uses equipment such as coating heads and coating wells to transfer Langmuir films onto solid substrates while preserving their properties such as density, thickness, and uniformity.
The services provided by our companyFLB300A LB membrane analyzerCharacteristics:
1. A small range surface tension sensor that accurately reads changes in surface tension values and monitors changes in surface tension values and film pressure using a special platinum plate suspension.
2. The powder mobile LB slot can be removed.
3. The LB slot is specially designed and does not use organic glue to avoid contamination. It is made of a single piece of pure polytetrafluoroethylene that is easy to clean, reliable, and durable. It is hydrophobic and not easily contaminated, and the substrate membrane pressure changes are small.
4. Automatically calculate surface tension and membrane pressure difference.
5. R-A, π - A, r-t, and π - t curves can be plotted.
6. Constant membrane pressure can be set for LB film transfer.
7. The centered lifting well is beneficial for the uniformity of monolayer LB deposition.
8. Heat/cool the aluminum substrate through an external circulating water bath to control the temperature of the sub phases.
9. By adjusting the horizontal adjustment feet of the frame, the LB slot level can be quickly and accurately calibrated.
10. Sliding obstacles can move repeatedly, compressing and expanding.
11. Reserved interface flow testing function.
