Features
Standard Langmuir Troughs are available in several sizes, small, medium or large and can be configured depending on the area of research. The smaller trough tops are preferable when using expensive molecules. The bigger systems provide more space for characterization instruments and provide a higher compression ratio.
KSV NIMA Microscopy Trough
Combines the Langmuir trough with a microscope for additional characterization. This special Langmuir Trough features an upright or inverted microscopy window to study morphology, phase changes and adsorption. The window allows high optical transmission down to a wavelength of 200 nm (suitable for visible light or UV microscopy).
Langmuir Ribbon Barrier Trough
is ideal for studying lung surfactant (DPPC) and other application where extremely high surface pressures are needed. The Langmuir Ribbion Barrier Trough enables the study of floating monolayers at high packing densities (e.g. > 70 mN/m for DPPC) by monolayer confinement. The PTFE-coated glass ribbon prevents any leakages that could occur in high pressures.
Liquid-Liquid Langmuir Troughs
Extends the capability of this instrument to use both liquid-liquid and air-liquid interfaces. The liquid-liquid interface is often used to study emulsion stability, properties of oil and gas, food, cosmetics, and pharmaceutical research.
Accessories
KSV NIMA Syringe
Pump for automated nanoparticle deposition which enables reproducable and accurante slow micropropulsion depostion of particles.
KSV NIMA Subphase Evaporation Compensation Tool
Ideal for long measurements or experiments at elevated temperatures. This tool prevents surface pressure variations and leakages.
