Blood separation membranes are essential components in diagnostic assays, enabling the efficient separation and isolation of plasma from whole blood samples.

At Fortis, we provide Poly-ether Sulfone (PES) Asymmetric Red Blood Cell Separation Membranes under our Primecare brand. These membranes are designed to rapidly separate red blood cells from plasma while facilitating plasma collection.

Our Primecare Membranes are asymmetric in structure, where blood enters through a surface with larger pores or openings (See below image). As the blood passes through the membrane, the red blood cells (RBCs) are trapped as they move progressively through smaller and smaller pores, while the resulting plasma exits from the other side of the membrane.
