General description

Device Configuration: 2 canisters

Steritest® NEO is a membrane filtration device for sterility testing of filterable pharmaceutical products. The device simplifies every aspect of testing, from handling to traceability. The closed system ensures that pharmaceutical products are never exposed to the environment, minimizes false positives, and offers the highest levels of quality & reliability. This test system offers an optimized and fully regulatory compliant testing process when used with the Steritest® Symbio pump, specific accessories and high-quality culture media and rinsing fluids. The Steritest® NEO Double Packed Device for liquids in large vials is gamma sterilized and double packed for the quick transfer into sterility testing environments, simplifying decontamination procedures and saving time. A vented needle adapter vents and transfers the test product from large volume containers with a septum to the Steritest® NEO devices. The red canister base indicates low absorption. Durapore® hydrophilic Poly vinylidene fluoride (PVDF) membrane and specific drain design. This optimizes the rinsing of products that inhibit microbial growth.


Steritest® NEO Device is used for sterility testing of liquids in large vials containing antimicrobial agents.

Features and Benefits

  • One-stop-shop for sterility testing with our devices, pumps, media, fluids, and services
  • Steritest® devices are manufactured in our Center of Excellence in Molsheim, France, with high-quality control standards maintaining the Certificate of Quality for each lot.
  • New needle design
The design of this new needle has been optimized with short needle length, grips, and ridges to offer dexterity and security to the operator while piercing the small container
  • Smarter workflow
The new Steritest® NEO cartridge device benefits from all the improvements such as colored clamps, graduations for accurate volume measurement, optimized identification, and traceability with the new peel-off label
  • Completely closed set up
Pharmaceutical products are never exposed to the environment during the testing process with Steritest® NEO devices. Filtration, rinsing, media addition and incubation are conducted within a closed system.
  • Consistent performance
100% integrity testing, strict physical and microbiological tests performed at every step of the assembly of the Steritest® NEO device before release from manufacturing.
  • New tubing disconnection tool
The Velax® cutting clamps are mounted on all Steritest® NEO devices and allow safe and easy cutting of the tubes.
