The Sentino® pump system is ideal for microbiological MF technique using Pall MicroFunnel™ filtration units. Designed to use peristaltic action to draw the sample through the filter and send filtrate directly to drain or waste collection. The housing is a PC ABS-blended polymer, the keypad and label PE, the pump head PEI with PTFE-filled PBT rollers. The fluid path adapter is PP.

• Safety: The system eliminates the need for a fluid trap under vacuum, preventing implosion accidents
• The disposable design also eliminates the need to clean and autoclave manifold set-up, saving valuable time
• Easy to clean: Shape of unit and construction materials are easy to wipe down with standard laboratory disinfectants
• EasySoft touch keypad has simple on/off function and pulse features to control filtration, no complicated programming

The peristaltic flow design pulls sample through the filter and fluid path eliminating the need for a vacuum source. It also ensures the fluid flows in one direction without the potential for back-up and contamination of analysis. Operating parameters are pre-set and fixed to best satisfy published requirements for MF technique in US EPA, ISO and ASTM methods; thereby eliminating the need for extensive validations. Fixed conditions also prevent changes to filtration parameters that may adversely affect colony recoveries and integrity of results.
