Microtrough G4 The Microtrough G4 is Kibron's largest Langmuir instrument, supporting LB-coating of up to 4 inch wa.. Product #: MTG4

Microtrough G4

Product Code: MTG4

Available Options

* Troughs:

You can choose troughs for your setup. We recommend selecting at least one trough as troughs are not included in the basic setup.


POM barriers are always included with the instrument. You can add other barriers if you need.

MTX Accessories:

Choose the accessories that you want with the instrument. You can also buy them separately.

The Microtrough G4 is a large, modern Langmuir trough, answering to the need for preparing larger samples in electronics industry and material science. The baseplate is built of robust 12.5 mm thick aluminum. The architecture of the instrument is very open and it has a standard optical breadboard along the edges (25 mm x 25 mm M6) for easy accommodation of auxiliary equipment - from Kibron or other manufacturers.

The water circulation channels for temperature control have been built into the baseplate. This facilitates removing, washing and exchanging the troughs, without the need to disconnect circulation tubing. The thick metal layer between the subphase and temperature channels reduces temperature gradients in the trough - this is a point which is rarely realized in designs were the temperature control channels are directly located below the PTFE bottom of the trough.

The instrument is available with POM barriers as standard and PTFE as optional. If the instrument is not directly suited to your needs, please inquire for customization.
