In 1976, Maths and Physics teacher M. Peter Mettenleiter and school lab assistant Klaus Kruse started to develop a practice-oriented student experiment system in line with demand for Mr Mettenleiter’s own classes at Schyrengymnasium Pfaffenhofen/Ilm. It took until 1988 when the company was officially established. The company name is an acronym for:

  • ME – Mettenleiter
  • KRU – Kruse
  • PHY – Physics

The correct pronunciation of our company name is /me’kru:fi/.

Here at MEKRUPHY GMBH we are dedicated to instil a fascination for the natural sciences in children and arouse and foster their innate curiosity. By doing so, we hope to increase the regard in which science is held by society and to sow the seeds for effectively combating the lack of qualified specialists in education, research and enterprise at an early stage.

By performing their own experiments students discover new scientific phenomena and patterns for themselves and can try to explain their findings using prior knowledge and experience. To achieve this aim, our company make sure they have the best and most suitable scientific equipment available to them. This is carefully designed for the age group using appropriate materials and colour.

Our maxim is:

“Give the best to the students and lighten the load on the teachers.”

Expertise and practical relevance

We have always been involved renowned educators and didactic specialists in developing and exhaustively testing the experiment sets and the accompanying experiment guides from the outset. Thanks to our close cooperation with schools and universities, our company has accumulated a comprehensive and in-depth understanding of how to design scientific experiments for schoolchildren and how to successfully master the challenges of the modern classroom.


Awards & Auszeichnungen

Mekruphy was honoured with the international coveted Worlddidac Award for its exerpiment sets in 2014, 2016 and 2018.


… I particularly enjoyed the comprehensive explanation surrounding the background of each experiment. This makes one feel well-prepared and able to address all of the children’s questions. To promote the children’s sense of orderliness, it would be advisable to have a picture of the instrument in its corresponding place. This way, the children can independently tidy up their experimental instruments.* Initially, I tested the “Magnetism” experiment kit with the preschool children. From the start, all the children were quickly enthusiastic about the experiment and showed great interest in magnetism. They asked many questions and would have liked to carry out further experiments that day. In summary, I can recommend the “Magnetism” experiment kit because it offers a wide variety of experiments, allowing one to specifically promote and support children’s curiosity and desire to explore. I am fully impressed by the “Plants” experiment kit because it is in line with our nature concept and playfully sparks children’s interest in this important area of “nature.” With the accompanying booklet for Kindergarten 4, it is possible to provide the children with a slow introduction, adjusting the difficulty levels from experiment to experiment. The age group for this experiment kit is diverse, making it useful for younger children as well. The magnifying glasses, in particular, were definitely a highlight for our children, as it was not only extremely fascinating for them to explore a world that is normally hidden from their eyes, but they were also very proud to work with these beautiful instruments. Overall, it can be said that this suitcase is definitely worth it and makes children’s eyes shine.
