Langmuir (LT) and Langmuir-Blodgett Troughs (LB) are used to fabricate and characterize thin films with controlled packing density.
Langmuir Troughs can fabricate the monolayer to a liquid-gas interface whereas Langmuir Blodgett Troughs can both create the monolayer at liquid-gas interface and then transfer the layer as a coating onto a solid substrate. This enables the creation of single-layer and multilayer films with precise control of thickness, molecular orientation and packing density. Standard Langmuir Troughs are available in several sizes depending on the need. The smaller trough tops are preferable when using expensive molecules whereas the bigger systems provide more space to be combined with characterisation instruments and provide a higher compression ratio.
The LB Troughs are also available in several sizes from small to large. Depending on the size of the system, you can deposit LB films on samples ranging in size from a few square millimeters to many tens of square centimeters (Roll to Roll LB Trough) . The LB dipping mechanism can also be easily fitted with a LS deposition kit for horizontal Langmuir-Schaefer deposition.
