The Kibron MicroTroughX is a versatile Langmuir instrument 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. MicrotroughX is available in small (S) and large (L).

Kibron MicrotroughXL is a medium sized Langmuir instrument. The core technology, Kibron’s sensor (0.2 microgram resolution), records surface pressure with a very high sensitivity, better than 0,01 mN/m, yielding excellent reproducibility. The instrument features adjustable feet and protective enclosure. Heat control plate with for connection to an external bath is available as an accessory.

We have two different trough materials available, namely PTFE (Standard) and stainless steel with PTFE edges. The hydrophilic bottom of the steel trough allows for a significantly smaller subphase volume. Trough models for various purposes are available in the webshop or on request. Other materials, custom troughs and designs, including previously sold troughs, are available on request. The standard package has POM barriers. PTFE barriers are available from the webshop or on request..

The instrument is controlled by the recently released FilmwareX4.0. The software has a intuitive design, which allows the users to effortlessly do and review experiments.

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. Please contact us at info@kibron.com for changes to the basic configuration, custom parts, and quotations.

We recommend that you look at the Microtrough G2 as well. It is our next generation trough with more features built into the standard setup.


The basic setup includes the following items:

#6702 Aluminium Base Plate with stepper motor for smooth compression, XL
#6034 Langmuir force balance for surface pressure measurements
#1500 Set of DyneProbes, 4 pcs
#6407 Set of Two Barriers (POM)
#3530 Sample cup (PP), set of 50 pcs (For calibration and surface tension measurements)
#6711 Acrylic cover box, XL

#6035 Ground cable
#6238 Connecting cable, 2pcs
#6240 Computer cable


Base mechanics 52 x 19 x 6 (h) cm ( 20 x 7.5 x 2.4 inches)
Electronics 27 x 23 x 8 cm (10.6 x 9 x 3.1 inches)
Total weight 3.55 kg (7.8 lbs)
Acrylic casing Prevents perturbation of the film by air flow and accumulation of dust into the interface. Allows for the use of protecting gas to reduce oxidation and photobleaching in fluorescence microscopy and spectroscopy.
Dimensions Outer base plate dimensions 51,6 x 19 cm (20,3 x 7,5 inches)

Control of film area

Barriers Made of hydrophilic, inert polymer (POM). PTFE barriers are available upon request.
Compression velocity Can be freely varied between 0 and 200 mm/min (one barrier)
Accuracy Better than 0.1 %
Barrier motion High precision microstepping motor guarantees extremely precise and smooth control of area
Software All measurements are computer controlled, with real-time display of retrieved data

Measurements of surface pressure (Surface tension)

Principle Wilhelmy method using a small diameter ( 0.51 mm) special alloy wire. No artefactual hysteresis as when using the conventional Pt-plates. No drying and accumulation of salt which cause significant errors when filter paper is used. Other probe materials and shapes available on request.
Dynamic range 0 to 130 mN/m
Resolution 10 µN/m (1.6 µg)
Temperature sensor KTY. Resolution 0.1 degrees.


Material Full PTFE or Stainless steel with PTFE edges. Several designs available on request.
User-defined designs are routinely made.
Volume 145 ml in Full PTFE Langmuir-troughs, and 270 ml in Full PTFE Langmuir-Blodgett troughs. 45-90 ml in stainless steel Langmuir trough. Subphase can be magnetically stirred. 300 µl in surface pressure measurements (Multiwell plate).
Detailed specifications are found under the particular troughs.
Area Inner area 39,3 x 5,9 cm (15,5 x 2,3 inches)



Here’s what our customers say:

University of the Basque Country

“The monolayer and Langmuir-Blodgett equipment of Kibron has renewed my interest in a technique that I remembered as clumsy and complicated. In addition, I have been nicely impressed by the kindness and efficiency of the Customer Service. My students are delighted with Kibron”.

Prof.Dr. Félix Mª Goñi Urcelay, Head of Unidad de Biofísica (CSIC-UPV/EHU) University of the Basque Country
