It is important to Th. Geyer to protect humans and the environment. Therefore, we mark especially sustainable products with the eco dot. To classify these products, we not only use the information we get from our suppliers. Additionally, our lab experts decide whether a product deservers the eco dot or not. This allows you to more easily find sustainable products for you laboratory – because we all have to work together towards a more sustainable world.
GREEN SOLVENTS
FOR SUSTAINABLE CHEMISTRY
We support the concept of Green Chemistry and the growing awareness of the environmental impacts of chemical products and their production processes. Green Solvents are a vital part of sustainable chemistry. Besides obvious “green” solvents such as water and ethanol, CHEMSOLUTE® contains “green” alternatives to commonly used solvents.
