Electropositive non-woven filter media

Proven Technology

Virus Sampler ProgramEvery NanoCeram® Virus Sampler uses Argonide’s patented electropositive non-woven filter media in a pleated cartridge configuration and is fully autoclavable. The original 5” model (VS2.5-5) is also sterile and sealed in a heavy-duty polybag for immediate use.

Meeting Rigid Testing Demands

The entire family of NanoCeram® Virus Samplers is capable of meeting the rigid testing methodology for virus sampling as specified by the EPA (see USEPA Methods of Virology, Chapter 14, April 2001) as well as the recent SM1615 Protocoal


Low Cost – High Value

The focus of the VS2.5-5 cartridge’s development was in response to the EPA’s desire for a low cost virus sampler. Target parameters included a cartridge capable of sampling 500 liters of river water, with high turbidity, in a period of 1-2 hours.

The NanoCeram® VS2.5-5 cartridge was tested by a continuous stream containing 250 NTU of 3 µm APS A2 fine test dust at 5.5 LPM (1.5 GPM). At 90 minutes it had filtered 119g of dust from 508 liters while maintaining <0.01 NTU in the effluent (99.996% retention) at which point the test was terminated.
