Riegler & Kirstein is a company devoted to the design of Langmuir troughs and layer-by-layer deposition and dipcoating devices for use in the scientific field of monolayers and Langmuir-Blodgett research. The design of our instruments is the result of many years of extensive lab-experience in the field of monolayers, LB-research, and polyelectrolyte layer-by-layer deposition ('self-assembly'). In fact, we do use our own systems in our daily research work. Accordingly, our instruments offer all the technical features necessary for optimum and most efficient laboratory use and handling. Our instrument design is based on the following principles: - Simple and self-explaining instrument operation. - Mechanical and electronic modularity, open architecture. - State-of-the-art mechanics and electronics. - Customer-specific equipment design. - Low prices.
