Steritest™ Symbio sterility testing pump

Whether you carry out your sterility testing in a cleanroom, isolator, or laminar flow hood, the Steritest™ Symbio Pump ensures reproducibility, while streamlining your workflow.


Key advantages of the Steritest™ Symbio pump

Reproducible test results

Steritest™ Symbio sterility testing pumps safeguard your testing procedure, ensure test method reproducibility and help you save time. The test method mode displays your sterility test protocols in an easy step-by-step way, including customizable handling information.


  • Cleanroom-friendly hardware: air-tight housing and passive cooling prevent particle emission
  • Two pressure modes—including automatic pumping speed reduction—alert the operator to reduce the risk of test interruption and minimizing the stress on any microorganisms that may be present
  • Easy to clean and resistant to gas decontamination in isolators


  • Reduced pump height for easy access in laminar flow hoods
  • Compact pump frees working space and loading capacity in isolators
  • Compatible with vertical and horizontal air flows


  • The automatic pump head closure ensures quick and easy tube placement, as well as reliable splitting of the liquid sample
  • Precise timer function: small volumes are sampled with high accuracy


  • The ergonomic shape of the housing allows easy tube loading; no risk of pinching gloves and consequent test interruption
  • Adjustable bottle holder height and orientable display for perfect screen visibility

User friendly

  • Clear user interface displayed on a 11 cm (4.3 inch) color LCD screen
  • Choice of operating language (Simplified Chinese, English, French, German, Italian, Japanese, Portuguese, Spanish, Russian or Turkish)
  • Test method library: store up to 250 filtration protocols and follow them step-by-step on the screen

Steritest™ Symbio sterility test pumps are designed to fit your testing environment

Steritest™ Symbio LFH Pump
Steritest™ Symbio ISL Pump
Steritest™ Symbio FLEX Pump
With its compact design, the Steritest™ Symbio LFH pump can be used comfortably in the smallest testing environments, including in a laminar flow hood, biosafety cabinet, cleanroom or even inside an isolator. The Steritest™ Symbio ISL pump is optimized for convenient sterility testing inside isolators. Its table-integrated design offers more working space and loading volume in isolators. The pump is compatible with all standard round table cutouts and is a perfect replacement for Steritest™ Integral and Steritest™ Equinox Isolator pumps (no need for table rework). The Steritest™ Symbio FLEX pump is very versatile, and can be installed in multiple ways, in either an isolator or a laminar flow hood. The pump is compatible with all standard round cutouts, and is also the perfect replacement for the Steritest™ Equinox Isofit pumps, as it will also match its oval cutout without the need for table rework.
