KSV NIMA Langmuir and Langmuir-Blodgett troughs are the leading and most widely used instruments for Langmuir film fabrication, Langmuir film characterisation (including microscopy) as well as Langmuir-Blodgett film deposition.
KSV NIMA Langmuir and Langmuir-Blodgett troughs are used for the fabrication and characterisation of single molecule thick films that offer precision control over the lateral packing density of molecules.
Langmuir troughs are used to create, modify and study monolayers at either the gas-liquid or liquid-liquid interface (Langmuir films). A Langmuir film can be defined as an insoluble monolayer of functional molecules, nanoparticles, nanowires or microparticles that reside at the gas-liquid or liquid-liquid interface. The fact that these molecules can move freely at the interface provide great flexibility for the control of the packing density and the study of monolayer behaviour.
The Langmuir Trough allows you to infer how particular molecules pack together while confined in two dimensions. The surface pressure-area isotherm can also provide a measure of the average area per molecule and the compressibility of the monolayer.
A Langmuir-Blodgett Deposition Trough is very similar to a Langmuir Trough: it also enables Langmuir film fabrication at the gas-liquid interface. In addition, it is equipped with a dipping well and a dipper for Langmuir film deposition onto solid substrates at a desired packing density (typically in solid phase).
