We offer almost all chemical elements of the periodic table (except radioactive elements) in very different forms and shapes.
Our ambition is to provide you with the highest quality display samples available in the world.
We produce unique chemicals such as 2D-material like Black Phosphorus, Black Arsenic and SIP, + SIP2.
We help universities, schools, museums, organizations and also private persons to build up their very personal periodic table display. Our strength is constant development and implementation of new ideas to make science accessible also to non-scientists. We believe that there is a very special beauty in every single ‘building-block’ of the universe and it is our passion to discover it.
Our selection of inorganic fine chemicals are very popular and are used in laboratories and institutes allover the world.
We are one of the first providers for 10mm Density standard cubes!
When a university asked us in 2009 whether we could offer absolutely plane-parallel and geometrically exact metal cubes made of high-purity monocrystalline materials with an accuracy of 0.005mm, we thought it would not be a big deal. What sounds simple at first turned out to be an extremely difficult task. A single company that manufactures special parts for aviation has agreed to give it a try with metals that are exotic for them. The cost was several thousand euros / piece !!
At that time we did not think that this product could also be of interest to collectors.
The purity of the materials, the precision and a flawless surface were our top priority. Our cubes should really represent the theoretical density of the elements as precisely as possible and at the same time be affordable.
In the meantime, our density cubes have become one of our best-selling items (unfortunately copied by many Asian sellers and now sold as cheap replicas with low quality) and we manufacture many of the cubes in our laboratory with a precision of 2 decimal places, either calibrated for weight or size.
It’s not that fast, as the final grinding takes between 1 and 5 hours per cube, depending on the material. This also explains the waiting times and the prices, which are not exclusively based on the value of the material.
