Langmuir tanks are used to obtain and study monomolecular layers at liquid-gas or liquid-liquid interfaces. Combined with an ascent system (Langmuir-Blodgett tank), they also enable the transfer of such layers onto solid substrates. Sequential immersion and ascent leads to the formation of multilayer coatings. We supply a full range of surface research products from the market leader KSV NIMA. In addition to standard tank sizes, custom tanks can be manufactured upon request, equipped with wells, spectroscopic measurement windows, baffles, reaction channels, and more. All tanks manufactured by KSV NIMA are made from a single piece of Teflon (PTFE), without welds, adhesives, or joints.<\/p>\n

The KSV NIMA LB system features easy-to-use and intuitive software. It allows the user to utilize numerous pre-programmed measurement methods for experiments using both standard Langmuir and Langmuir-Blodgett tanks. Previously saved methods can be modified to meet the user's needs. The wide range of data and parameters saved allows for easy selection of specific information. Recorded parameters include: number of measurement points, time, barrier position, barrier velocity, trough top surface area, layer area, dipper position, dipper velocity, layer number, diffusion coefficient, total diffusion, temperature, pH, and surface potential.<\/p>\n

    \n
  • Standard software allows you to:<\/li>\n<\/ul>\n

    \u2013 measurement of compression\/relaxation isotherms
    \n\u2013 analysis of reaction\/interaction kinetics
    \n\u2013 analysis of particle penetration into the monolayer, solubility and binding of biomolecules
    \n\u2013 measurement of isobars and isochore
    \n\u2013 measurement of the viscoelastic properties of the layer (oscillating barriers)
    \n\u2013 measurement and control of immersion speed<\/p>\n

    After conducting an experiment, the user can return to the saved data and analyze the results. Clicking on a specific experiment displays the data, and experimental data from different experiments can be displayed in a single graph for comparison. The software also allows for viewing and editing the measurement setup, which is very helpful when data needs to be recalculated based on new material data.<\/p>\n

    Product advantages:<\/strong><\/p>\n

    \u2013 Modern and intuitive software.
    \n\u2013 Ultra-sensitive surface tension meter for highly precise measurements. Also available with platinum plates, platinum needles, or paper plates.
    \n\u2013 The open structure of the system ensures easy and quick replacement of bathtub trays, even in a matter of seconds, as well as easy cleaning or modification of the system.
    \n\u2013 The channels for L bathtubs and LB bathtubs are made of a single piece of Teflon, which eliminates leaks, does not contain potentially contaminating glue in the construction and also facilitates the cleaning process.
    \n\u2013 Compression barriers made of hydrophilic Derlin to increase monolayer stability. Hydrophobic PTFE barriers are also available upon request. Furthermore, a sturdy metal frame prevents deformation of the barriers over time.
    \n\u2013 The delicate design of the frame allows the combination of optical techniques for more accurate characterization, such as PM IRRAS infrared spectroscopy, Brewster angle microscopy, fluorescence microscopy.
    \n\u2013 Symmetric compression for homogeneous monolayer packing. Asymmetric compression is optionally available on each device.
    \n\u2013 The centrally located dipper well ensures uniform deposition of the monolayer on the sample surface.
    \n\u2013 Controlled sub-phase bath temperature using a built-in heating jacket connected to an external circulation thermostat (thermostat available separately).
    \n\u2013 Adjustable legs of the bathtub frame allow for quick leveling of the bathtub and, when unscrewed, allow for placement, for example, on a microscope.<\/p>\n
