# KSV Langmuir-Blodgett Minitrough

KSV Langmuir-Blodgett Minitrough. Please see manual.

## Specifications/Capabilities

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.
                    - Dwell times: 0 s to max. 9999 s, individual adjustment for upper and lower endpoint substrate movement.
                    - 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.
