Steritest® Symbio Sterility Testing Pump Guide

Sterility testing is a validation protocol for products manufactured according to GMP to confirm their sterile status. Our sterility testing Steritest®Symbio pumps, accompanied by our smart accessories, are designed for ideal integration into any testing environment, making reliable sterility testing easier than ever.


Steritest® Symbio pumps when combined with our wide variety of membrane filtration devices and high-quality culture media and rinsing fluids offer an optimized and fully regulatory-compliant testing process (USP 71, EP 2.6.1, and JP 4.06). 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, maximizing safety, confidence and convenience.


The key advantages of using Steritest® Symbio Pumps

Steritest® Symbio Pump

Reproducible test results

The 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.

  • Two pressure modes—including automatic pumping speed reduction—alert the operator, reducing the risk of test interruption and minimizing the stress on any microorganism present
  • Easy to clean and resistant to gas decontamination in isolators

Intelligent design

  • Reduced pump height for easy access in laminar flow hoods
  • Compact pump frees up 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 and 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, with no risk of pinching gloves and test interruption
  • Adjustable bottle holder height and orientable display for perfect screen visibility

User friendly

  • Clear user interface displayed on an 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
