The Enzymatic Sampler.
Enzymatic Sampler: A Deep Submergence Tool for the In-Situ Instantaneous Preservation of Living Organisms
A tool for the fixation of deep-sea organisms at habitat pressure immediately following collection in order to conduct investigations of enzyme activity and function. The sampler is a two-chambered system. The Fixative Actuator chamber stores a chemical fixative that is subsequently injected via the Main Piston into the Bio- Chamber, in which freshly-collected organisms reside. The sampler is designed to mount on a submersible, with operational depth up to 4500m. This sampler has been used sucessfully to preserve hydrothermal vent mussels, clams and shrimp (using a newly designed slurp lid) in situ.
