KSV Langmuir-Blodgett Assembly and Deposition Trough

Reserve Equipment

Information the equipment can provide

The system can be used to fabricate and characterize multilayer films with precise control of lateral packing density.

Model: KSV MiniTrough


  • PTFE trough with a surface area of 273 cm^2 (L364 x W75 x D7 mm^3), a dipping well (L37 x W37 x D64 mm^3) and a subphase volume of 280 ml
  • Hydrophobic (PTFE) and hydrophilic barriers (polyacetal or Delfrin) are used to adjust the surface pressure. Barrier speed: 0.01 mm to 400 mm/min
  • The surface pressure is measured by using the Wilhelmy plate method (Pt plate or paper). The total measurement range ofthe balance is +/- 2000 mg. The width of the platinum Wilhelmy plate has been chosen so that 1 mN/m corresponds to 4 mg
  • A fiducial camera allows inspection and image capture of patterns and drops as well as alignment for multilayer processes.
  • The deposition system consists of a dipping arm with a speed range between 0.1 to 85 mm/min
  • Monolayers and multilayers transfers
  • Software controlled operation
  • Max size of substrate 60 x 35 mm
