"Coloured clamps ensure ease of tracking tubing to canisters and make it easier to differentiate between media canisters, reducing the chance of wrong incubation. The new tear bags are easy to open."

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 µm pore size filter, and all inhibiting compounds are rinsed using a suitable rinse solution. Appropriate media, 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.
Steritest™ NEO devices combined with our peristaltic pump, specific accessories and high quality culture media and rinsing fluids offer an optimized testing process compliant with USP <71>, EU Pharmacopoeia < 2.6.1> and JP Pharmacopoeia <4.06>.
Select the right sterility testing membrane filtration solution according to your sample.

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 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.
