MB Bronze Messenger for Closing Mechanisms

Precision Activation with the MB Bronze Messenger

The essential component for triggering deep-water closure mechanisms, engineered to guarantee perfect sampling in plankton nets and oceanographic bottles.

The MB Bronze Messenger is a cornerstone of aquatic sampling engineering, acting as the vital link between the researcher and the submerged equipment. Designed to slide with precision along the main line, its function is to unfailingly activate the closing mechanisms of plankton nets, oceanographic bottles, and Ekman grabs. Manufactured from high-density bronze, this device ensures a steady descent and effective impact, allowing the capture of underwater nature to occur at the exact moment and depth required, protecting the purity of every collected sample.
