I found a very old posting from Dr Sarah Butcher regarding a need for filter discs to filter virus. I've attached a few files that may be of interest to Dr. Butcher, or anyone else there that is involved in projects of this type. This includes our Virus Sampler which is a pleated filter cartridge intended for use in determining viral contamination of drinking water supplies.
Please let me know if you are interested and if you have additional questions.
