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 minimizes false positives and offers the highest levels of quality and reliability. This device ensures that pharmaceutical products are never exposed to the environment during the testing process. 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 Antibiotics is gamma sterilized and double packed for the quick transfer into sterility testing environments, simplifying decontamination procedures and saving time. A separate vent needle is included for the transfer of the test product, culture media or rinsing buffer. 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.
