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.

Sentino® Filter Funnels

Easy to use, disposable funnels for microbiological monitoring of aqueous solutions


  • Easy Placement - The Sentino Filter Funnel and Adapter are designed with a press-fit seal, membrane guides and forceps access point allowing for simple set up and membrane removal. This will speed up the process time in the laboratory.
  • Risk Reduction - The Sentino Filter Funnel and Pall Membranes reduce the risk of a contamination event as compared to reusable funnels. The filter funnels are gamma irradiated eliminating the need for autoclaving or any other cleaning/sanitizing techniques. This will save time and money by eliminating the need to investigate contamination events resulting from the reusable devices.
  • Regulatory Compliance - Membrane filtration is the method of choice for microbial monitoring of aqueous solutions as specified in "Standard Methods for the Examination of Water and Wastewater" and Pharmacopoeias worldwide.
  • Easy and accurate sample measurement
