DOCUMENT CENTER THE NEW ELECTRONIC LEYBOLD LIBRARY ensures the structured display and maintenance of all technical documents, such as Advanced Science Kits and Science Kit literature, instructions for demonstration tests or the operating manual, in a consolidated format. offers a convenient keyword and catalog number search to quickly locate the desired information. several versions of a document, including maintenance. current documents available at all times via free online updates, can also be automatic.

The Document Center gives you digital access to all technical documents we have available in the form of comprehensive literature packages.

After a one-time installation, the documents can then automatically be kept up to date, if so desired. The literature packages are clearly shown in a table of contents that leads you directly to the target document.

The more literature packages you install, the more entries the table of contents includes.

Furthermore, the convenient search function helps you locate the desired information. Besides the documents, literature packages can also contain application data. So for example loading settings and examples in CASSY Lab from an experiment description contained in a literature package can be done with a single click of the mouse.

If the student and teacher versions of a literature package are installed, then switching between versions can be done with a single click of the mouse. Student documents can be completed in the Document Center and saved as a record or printed.

ADVANCED SCIENCE KITS SYSTEM EXTENSIONS Technical innovations will soon be incorporated into the curricula of the final years of secondary school. We are therefore consistently expanding our successful Advanced Science Kits system to adapt to these special demands.

WORKSTATION FUEL CELLS The fuel cell workstation is ideal for student experiments throughout secondary schooling, featuring ease of use of circuitry for the experiments.

Experiment examples:

Investigation of the mode of operation of solar cells, electrolyzers and fuel cells Solar power‘s dependence on illuminance and angle of installation Characteristic curves and effectiveness of electrolyzers and fuel cells

WORKSTATION ELECTROCHEMISTRY The electrochemistry workstation comprises a work surface that can also be used as storage. Inside are 2 cell blocks made from resistant plastic that can easily be screwed into place. This also allows for easy cleaning.

Filter paper is inserted as a diaphragm between the cell blocks. Four galvanic elements can be set up simultaneously. It enables experiments to be made in the following subject areas:

Electrochemical potentials pH value and redox potentials Applied electrochemistry

EXPERIMENT SET MAGNETISM – ELECTRICITY – ELECTRONICS The devices‘ configuration and the proper experimental instructions are ideally tailored to the demands of the standardized high school diploma. The experiment set covers more than 40 testing proposals, including in the areas of induction, magnetic fields, characteristic curves and resonant circuits.

EXPERIMENT SET ENERGY Current physical fundamentals like energy conversion and storage can be treated with graphically qualitative and quantitative experiments.

The experiment set is ideal for experiments with wind and radiation energy. Conversion processes connected one after the other („chains“) can help clarify the subject of energy „loss“ in connection with notion of efficiency.
