Green house gas emissions might lead to a 'collapse' of marine species and thus of the food chain. 10 to 12% of the species might disappear if the temperature increases by 2°C compared to thepre-industrialera. Advances in research regarding the behavior of the marine world using protein markers, genetics and direct observations allow researchers to better apprehend the biodiversity and ecological balance. As these researches are characterized by a large variety of life forms, researchers need a flexible tool to prepare their sample before proceeding to molecular down stream analysis. Bertin Instruments offers a broad range of robust, efficient and flexible homogenizers based on the bead beating technology, to grind any biological sample while maintaining reproducibility amongst biological replicates and eliminating cross-contamination.
