Pioneering Excellence with New Steritest™ Symbio Pumps

MilliporeSigma is a renowned expert in sterility testing. When we invented in 1974 the first closed membrane filtration testing device, Steritest™, we made sterility testing reliable.
Reliable sterility testing is now even easier with our new Steritest™ Symbio sterility testing pumps. They will speed up and streamline your workflow, maximizing safety, confidence and convenience.

The Solution to All Your Testing Problems

Easy-to-Use Design

  • 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


  • Cleanroom-friendly hardware: air-tight housing and passive cooling prevent particle emission
  • Two pressure modes – including automatic pumping speed reduction – alert the operator, reducing 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


  • The housing’s ergonomic shape allows easy tube loading; no risk of pinching gloves and consequent test interruption
  • Adjustable bottle holder height and tiltable display for perfect screen visibility
  • Buttons designed to be operated with isolator gloves


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


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

The Steritest™ Symbio ISL Pump
The Steritest™ Symbio ISL Pump is optimized for extremely convenient sterility testing inside isolators. Its table-integrated design offers more working space and loading volume in isolators. What’s more, its ergonomic buttons and knob can be easily operated while wearing isolator gloves. The pump is compatible with all standard round-table cutouts and is a perfect replacement for Steritest™ Integral and Steritest™ Equinox Isolator pumps (without table rework). With its compact design, the Steritest™ Symbio LFH Pump can be used comfortably in the smallest testing environments, including in the laminar flow hood, biosafety cabinet, cleanroom or even inside an isolator. This 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, as it will also match its oval cutout without the need for table rework.
