NEW Steritest™ NEO device, the fourth generation of Steritest™ devices

The membrane filtration sterility test is the regulatory method of choice for filterable pharmaceutical products. The test is particularly suitable for samples containing preservative, bacteriostatic or fungistatic compounds, which inhibit microbial growth of potential contaminants. With membrane filtration, microorganisms are retained by a 0.45-micron pore size filter, and all inhibiting compounds are rinsed using a suitable rinse solution. Appropriate media, which are selected based upon their ability to support the growth of anaerobic and aerobic microorganisms, are then transferred to the membrane filters. A 14-day incubation period is required to obtain final test results. With our new device, we are raising the industry‘s standards, and driving innovation to provide you the most secure and reliable test ever.


New features


Color Clamp Canister

Colored clamps

Prevent any filling errors and improve your workflow clarity, thanks to the pre-installed colored clamps and the existing blackline, for accurate media filling.


25 mL volume graduation

25 mL volume graduation

Be precise and improve your workflow accuracy through the addition of a 25 mL graduation line and volume engraved in the Steritest™ NEO canisters.


Placement mark

Placement mark*

Be sure to place the Steritest™ tube in the pump head precisely using the new placement mark.



Easy opening

Easy opening

Opening of the accessory bag is now really easy and improves your workflow convenience thanks to the pre-cut line. No more need of scissor.



Color coding

Color coding

Clear packaging identification: The selection of the appropriate box of Steritest™ NEO will be facilitated thanks to the new designed label using color coding based on canister base color and using a needle/application drawing.


Peel-off label

Peel-off label

Peel-and-stick label to place in a lab notebook for improved tracability.

Meet the industry benchmark

  • Minimize false positives: closed Steritest™ NEO filtration devices reduce the risk of false positive results and avoid costly investigation and possible batch loss. There are no open containers or membrane manipulations, which could increase the risk of adventitious contamination.
  • Reduce false negatives: Steritest™ NEO filtration devices are the right answer to the danger that false negative results pose to patients. Through specific membranes, unique sealing technology and optimized device design, the unit allows efficient elimination of bacteriostatic, fungistatic or bactericidal agents.
  • Easy Identification with color coding and optimized traceability.
  • Quality check: each Steritest™ NEO device is subjected to rigorous in-process and release quality checks including 100% membrane and canister integrity tests as well as intense physical and microbiological testing. The detailed certificates of quality are available for download from our website.

Steritest™ NEO devices are color-coded for easy identification

For products without antimicrobial agents For antibiotics and products with antimicrobial agents Increased chemical compatiblity

Blue canister base indicates mixed esters of cellulose membrane. This membrane provides an optimal filtration flow rate for standard products Red canister base indicates low absorption Durapore® PVDF membrane and specific drain design. This optimizes the rinsing of products that inhibit microbial growth. Green canister base indicates low absorption Durapore® PVDF membrane,specific drain design and polyamide canister polymer. This optimizes the chemical compatibility of products dissolved in solvents.
