KSV 2000 - Highly Sophisticated LB system

KSV 2000 System is a modular Langmuir trough system which expands from a conventional film balance to a high performance Langmuir-Blodgett instrument or to a fully equipped alternating multilayer Langmuir-Blodgett system. The difference compared with the KSV 5000 Systems is that the position of the holders for the surface balance and dipper are constant and they are moved manually up and down.

The heart of the system is the Interface unit with the barrier drive and the system set-up is built around it by using the modules and accessories. All the modules are easily plugged into the Interface unit and the system set-up is factory installed and ready to use. The configuration can be up-graded later with various accessories and modules.

KSV 2000 System is available in three basic modular set-ups: System 1, System 2 and System 3.Barrier drives included in each system can be used for both single sided or symmetric compression. Although all systems include one standard trough it is possible to use almost any kind of custom made trough (width, length, depth, symmetric or single sided compression etc.) with the different systems.

KSV 2000 System 1

Langmuir film balance for conventional monolayer analyses and Langmuir-Film experiments. Biomembrane and enzyme kinetic reaction studies. Upgradable to System 2 and 3.

Standard System 1 configuration:

+ Interface unit with power supply, computer interface and displays for measuring
   parameters, one barrier drive
+ Film balance with a platinum Wilhelmy plate
+ Trough made of one solid piece of PTFE with 2 Delrin barriers
+ Remote control key pad for operation of the instrument without PC control
+ Software written in C++ compatible with all Windows operating systems

KSV 2000 System 2

Langmuir-Blodgett instrument for unsupervised deposition of ordered multilayer LB-films and for System 1 applications. Upgradable to System 3.

Standard System 2 configuration:

+ Interface unit with power supply, computer interface and displays for measuring
   parameters, one barrier drive
+ Film balance with a platinum Wilhelmy plate
+ Film deposition system with sample holder clip made of Delrin
+ Trough with dipping well made of one solid piece of PTFE plus 2 Delrin barriers
+ Remote control key pad for operation of the instrument without PC control
+ Software written in C++ compatible with all Windows operating systems

KSV 2000 System 3

Alternate Multilayer Layer Langmuir-Blodgett system for unsupervised deposition of ordered layers of two different monolayer molecules and System 1 and System 2 applications.

Standard System 3 configuration:

+ Interface unit with power supply, computer interface and displays for measuring
   parameters, two barrier drives
+ Two film balances with platinum Wilhelmy plates
+ Unique alternate film deposition system with sample holder clips made of Delrin
+ Double trough with dipping well made of one solid piece of PTFE plus 4 Delrin barriers
+ Remote control key pad for operation of the instrument without PC control
+ Software written in C++ compatible with all Windows operating systems
