KSV Langmuir-Blodgett Minitrough

Film Deposition System:

• Control and operation: Software controlled unsupervised and automatic film depositions.
• Deposition speed: Standard range 0.1 to 100 mm/min. Speed adjustment increment 0.1 mm.
• Length of deposition arm stroke: 60 mm.
• Deposition cycles: 1 to unlimited depositions. Number of consecutive depositions dependent of substrate and trough film area.

• Max. size of substrate: 60 x 30 mm (100% immersion).
• Type of deposition motor: Servo controlled DC motor.

Film Pressure Measuring System:

• Measuring principle: Wilhelmy plate, platinum or paper sensor element connected to microelectronic feedback system for surface pressure control. Software controlled operation, user programmable process parameters.
• Film balance measuring range: 0 mN/m to 125 mN/m.
• Resolution: 4 ?N/m.
• Surface area regulation: Symmetric compression of monolayer by inwardly moving barrier. Software controlled operation and user programmable process parameters.
• Surface barrier: Made of hydrophilic, optionally hydrophobic, material.
• Compression speed: 0.02 mm-min^-1 to 200 mm-min^-1
• Inaccuracy: Less than 1%.
• Barrier drive: Servo controlled DC motor.

Trough:

• Material: Solid, non porous cast-moulded PTFE. No glue or o-ring seals. Aluminium base plate with built-in water channels for temperature control of the subphase. PTFE thickness at trough bottom 1.15 mm.
• Size: 260 mm x 75 mm x 5 mm.
