3 reasons to invest

Quality

Single piece solid PTFE trough tops including the dipping well enable easy cleaning without any contaminating glues or coatings. Adjustable legs, trough top locating pins, barrier limit switches and overflow channels ensure safe and reliable use of the system. 

 

Usability

The system uses standardized Wilhelmy method with platinum plate for surface pressure sensing. You also have the option to use disposable paper plates to avoid cleaning. The powerful KSV NIMA LB software integrates all controls and data analysis into the same software, including different characterization tools.

Versatility

Specialized characterization tools ensure floating thin layer quality both prior to and after the coating process. Open modular design with simple trough top and barrier placement enables easy integration to characterization systems, upgradeability and easy cleaning of parts. 

Roll-2-roll2

New in

Roll-to-roll LB Trough

We now welcome a new special system for high throughput. Roll-to-Roll LB (R2R LB) is a novel process that broadly widens the possibilities of the LB technology.

In the R2R LB process, a flexible substrate is fed continuously into the trough where it passes through the monolayer of nanoparticles or other material. This enables coating large substrate areas quickly with precise control over the deposition parameters. 

 

Troughs

Troughs for every need

We offer a wide selection of L&LB Troughs with various sizes and functionalities. Our L&LB systems are fully modular, and one frame can be used for different sizes and types of trough tops. In addition to the standard offering below, custom trough tops can be created upon request.

* The Liquid-Liquid Trough is deeper than a standard trough as this allows for the two liquid phases. The value in the brackets corresponds to confinement of the lower phase (other value for the upper phase).
** The Alternate-Layer Deposition Trough is made of two separated compartments for creation of two monolayers simultaneously.

Software

KSV NIMA LB software

The KSV NIMA LB Software is a powerful tool for creating coatings and studying Langmuir films. Based on 30 years of experience, KSV NIMA LB Software includes all the tools needed for effective and easy measurements and data processing.

The versatile measurement modes enable measurements from dipping all the way to compression isotherms, adsorption studies and interfacial rheology. The software saves the entire measurement setup together with the results for convenient analysis. All data can be easily viewed, plotted, reported and exported as needed.

Measurement features

  • Coating mode, for depositing material layer, including a coating effectiveness parameter transfer ratio, keeping the packing density constant throughout dipping
  • Compression/relaxation isotherms, for molecular interactions and phase changes
  • Isochores/isobars, by automatically keeping the pressure stable and following temperature/area changes
  • Monolayer kinetics, for enzyme, polymerization or any other zero-order reactions
  • Adsorption and penetration of enzymes, proteins, peptides and similar molecules
  • Interfacial rheology, for viscoelastic studies of Langmuir films, for emulsion or foam stability, with oscillating barriers method
  • Integrated KSV NIMA characterization tool functions, for easy integration, such as automatic image recording based on surface pressure when combined to KSV NIMA MicroBAM

Computer requirements

  • 1 GHz processor

  • 1 GB RAM

  • 40 GB hard disk drive (20 GB free)

  • 1 USB-port

  • Windows 10

  • Accessories such as water bath and MicroBAM require an additional free USB port

Vacuum Pump Based Horizontal Dipping Clamp (Langmuir-Schaeffer)

To perform horizontal LS deposition on your Langmuir, Langmuir-Blodgett or Microscopy Trough, you will need a dipping mechanism and a Langmuir-Schaefer holder. The holder consists of a suction pump connected with flexible tubing to a sample holder rod. On the end of the sample holder is a soft rubber suction cup that creates a vacuum when brought into contact with a substrate.

"We are using LB troughs to try to accumulate the polymer on a substrate. Because of its user-friendly features, KSV NIMA LB troughs are the best choice. Also, since replacement of students regularly occurs at University lab, the easy to use KSV NIMA trough, I believe, really fits this type of environment.”

“We are creating cutting-edge nanoparticle coatings with our KSV NIMA Langmuir-Blodgett system for use in advanced future applications. We are working, for example, on dynamic smart nanoparticle-based window coatings that have the potential to make an enormous contribution to saving energy worldwide. We are using the KSV NIMA Langmuir-Blodgett technology as it allows us to control the properties of our coatings very precisely: packing density, coating layer thickness, flexibility in using different particles. With all these benefits combined with the quality and knowhow from KSV NIMA, it is a pleasure to work and collaborate with them.”

“We are using the LB to prepare LB films of phthalocyanines on ITO (indium tin oxide) to use them as voltametric sensors. We’ve recently started to prepare LB films of lipids/enzymes/phthalocyanines to also be used as electrochemical biosensors. We need KSV NIMA LB because the high order degree allows to attain better quality and more reproducible voltagrams. In the case of biosensors, the enzyme is immobilized in an environment similar to a cell membrane, resulting in higher sensitivity. KSV NIMA and Lasing provide great and friendly service, with prompt technical support with technicians who are thoroughly familiar with the instruments”.
