BACTRON Anaerobic & Hypoxia Workstations

SHEL LAB Bactron Anaerobic Workstations have made a name for themselves over the last 2 decades. As more labs realize the cost savings involved with moving from vacuum jars or bags to anaerobic workstations, they also begin realizing the improvement in successful culturing and identification. The Bactron anaerobic environmental chamber is designed to allow efficient and dexterous glove-free handling and inspection of samples. Modular systems within the Bactron anaerobic chamber facilitate the completion of procedures from unpacking material to inoculation, incubation, inspection and recovery--all without a single exposure to oxygen.
