The Medium LB Deposition Trough has a subphase area of 30x10cm and a maximum monolayer containment area of 265cm², suitable for high compression of a larger range of molecules. Approximately 185ml of liquid is required to form a subphase. The larger area improves positional accuracy of the surface pressure-area isotherm plots from which the area per molecule is determined. This trough comes with a 40mm stroke length LB dipping mechanism.

The dipping well has dimensions 50x22x30mm depth and is ideal for deposition of many layers on most substrate types including quartz crystal substrates for QCM monolayer mass measurements. Langmuir-Schaefer horizontal dipping is also possible on this trough.
