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.

Borosilicate glass 3.3. Conformity certified, with batch certificate. With NS and PE stoppers, to DIN EN ISO 1042. Calibrated to contain (IN) and all the tolerances are according to DIN/ISO Class A standards.
Developed for preparatory and analytical purposes. Suitable for biochemistry, biotechnology, microbiology, microanalysis. Can even be used in strong acids and alkalis, and in all solvents and oxidants. Suitable for vacuum and high-vacuum distillation. Reduces distillation times in rotary evaporators. No abrasion, absorption of substances or solvents. Softening (evaporation) occurs at 2500°C. Can be sterilised by dry heating. Effective in even the smallest volumes of liquid, even after multiple interruptions. Prevents any bumping. Highly resistant....

Overhead stirrer designed for simple stirring tasks for quantities up to 15 l (H
2O). It automatically adjusts the speed through microprocessor controlled technology within the speed range of 0/30 to 2000 rpm. Safety circuits installed ensures automatic cut-off in an anti-stall or overload conditions. Continuous comparison of shaft speed to desired speed is maintained and variations are adjusted automatically. This guarantees a constant speed even with changes in viscosities of the sample....
