Steritest™ Symbio Pumps

Designed to integrate perfectly into all testing environments, streamlining your workflow, maximizing safety and convenience.


When Millipore invented the Steritest™ closed filtration device 40 years ago, we made sterility testing reliable. Today we are making it easy, with our new Steritest™ Symbio Pumps for sterility testing.

The compact design and air-tight housing of new Steritest™ Symbio Pumps for sterility testing ensure easy handling in laminar flow hoods, isolators and clean rooms. With the pump’s low height and ergonomic design, the loading with Steritest™ EZ filtration units is extremely easy. The automatic closure eliminates the risk of glove pinching and ensures reliable splitting of the liquid sample.

You can also adjust the height and angular position of the bottle holder. Another important feature is the drain tray, which we designed to minimize splashing under the canister base. Two pressure detection modes - including automatic pumping speed reduction - alert the operator, reducing the risk of sterility test interruption and minimizing the stress on microorganisms.

Steritest™ Symbio Software - a user-friendly PC software - helps to ensure sterility test reproducibility. Once the test methods library has been created, you can easily transfer the selected test method to your pump.

The new color user interface assists the operator to perform the sterility test step by step. Information is available in 8 languages (Simplified Chinese, English, French, German, Italian, Japanese, Portuguese or Spanish).

The following range of Steritest™ Symbio Pumps for sterility testing is available: Steritest™ Symbio LFH
  • Reduced pump height for easy tube loading behind a laminar flow hood window
  • Clean room-friendly hardware: air-tight housing and passive cooling prevent particle emission
  • Its unique profile, compatible with both vertical and horizontal flows, prevents undesirable air turbulence, eliminating the risk of false positives
Steritest™ Symbio ISL for usage in isolators
  • Very compact pump, frees work space and loading capacity in isolators
  • Perfect replacement of existing/former/current pumps without isolator table rework
  • Buttons designed to be operated with isolator gloves
  • Easy to clean and resistant to gas decontamination in isolators
Steritest™ Symbio FLEX

  • Perfect replacement of Steritest™ Isofit pumps without isolator table rework
  • Compact pump, frees working space and loading capacity in isolators
  • Versatile: 2 installation heights possible in standard or half suit isolators, also compatible with laminar flow hoods
