MicroTroughX – multipurpose Langmuir and Langmuir-Blodgett instrument
With the universal Kibron MicroTroughX you can study isotherms, lipid monolayers, deposit LB films and much more – with unparalleled sensitivity and precision.
The Kibron MicroTroughX is an all-in-one lab tool enabling researchers to carry out a variety of surface chemistry experiments. Using Kibron accessories you can convert the instrument into a Langmuir-Blodgett trough, a standard tensiometer, a surface potential recording device, just to name a few examples.
Kibron MicrotroughXL has an extended area (with our novel Precision Plus trough) compared to the standard model MicroTroughXS.
The core technology, the proprietary Kibron sensor (0.2 microgram resolution), allows to detect surface pressure and measure compression isotherms with a very high sensitivity, better than 0,01 mN/m, yielding excellent reproducibility.
The technology allows also for very small subphase volumes with regard to both surface tension and pressure measurements; accordingly, LB coatings can be deposited on small surface area substrates.
Kibron MicroTroughX has a compact, robust construction, insensitive to vibrations. It is truly portable and can be set up for use within 5 minutes, requiring no vibration isolation table. The user friendly software allows the beginner to make an effortless start and have immediate control over all MicroTrough operations. The trough basins are easy to maintain and inexpensive, meaning each user can have his/her own.
Comparison with troughs from other companies - apples and oranges? Definitely not so! Kibron Langmuir-troughs involve major innovations, immediately obvious to those familiar with this surface chemistry technique. Starting from the Kibron high precision microbalance with better than 0.2 microgram resolution, to the use of high-tech materials and easy-to-use, intuitive software, Kibron troughs are in a class of their own. For more detailed listing of the advantages of Kibron Microtrough, see Features & benefits.
Importantly, because of the sensitivity of the balance, we do not need to have a large meniscus, and only a needle, our precision-manufactured Dyneprobe is enough to record surface pressure. The beauty of this technique is demonstrated by looking at Kibron AquaPi in action. Further, we never recommend the use of filter paper as a Wilhelmy plate as this results in the notorious chromatography effect: loss of materials from the film and erraneous area/molecule values.
Kibron troughs were designed by scientists for scientists: we know surface chemistry, from basic science and the classroom all the way to leading edge research.
