A potentially improved approach to methylene blue virus inactivation of plasma: the Maco Pharma Maco‐Tronic system

. Plasma was subjected to methylene blue (MB) photochemical virus inactivation using the Maco Pharma Maco‐Tronic system which allows three units to be illuminated together, thus reducing processing time. The plasma bag system used incorporates an integral membrane plasma filter and a dry MB pill which dissolves in the plasma to give a 1‐µm concentration. There is computer‐controlled processing and datalogging.
