Hi Vincenzo,

BioMerieux system (semi-automated) based on Boom's technology is dedicated to feces. Some people use it in clinical labs.

Vincenzo Costantino

Hi Ewa,

many thanks for your answer. In Masmec Biomed, we just produce automated workstations for DNA, RNA and miRNA extraction. I am looking only for a kit to use for our workstation.
