The Para-Pro™ fc50 is Alpha Tec Systems' closed parasite concentration filter. This concentrator has a patent pending conical design that nearly doubles the surface area available for filtration, when compared to conventional closed concentrators. This increased area allows for faster, more effective filtration and improved recovery of parasites. The Para-Pro™ fc50 is designed to connect directly with parasitology transport vials to allow for filtration without spillage or odor.
