Polycap™ SPF (Serum Prefilter) is an exceptional product that is optimized for prefiltration applications and is typically used upstream of a Polycap AS or a Polycap PES capsule.
Serum is difficult to filter because it contains a high degree of loading of complex particulates, lipids, triglycerides, and lipoproteins that clog filters. When filtering serum without proper prefiltration, membrane filters clog rapidly.
