Sentino® Microbiology Pump

Maximize Workspace and Minimize Contamination Risk


  • Compact design – Small footprint frees valuable benchtop space and provides flexibility in arranging workspace for optimal efficiency and workflow.
  • Minimal height – Allows convenient use in a hood fitted with a sash that can limit upward range of motion during routine analysis.
  • Disposable fluid path – Simple to load and completely disposable to eliminate potential biofilm build-up. There is no need to clean, wrap, and autoclave a bulky multi-place manifold. The potential for sporadic and unnecessary contamination is removed.
  • Peristaltic flow design – Pulls sample through the filter and fluid path eliminating the need for a vacuum source. Also ensures the fluid flows in one direction without the potential for back-up and contamination of analysis.
