Individually packed and sterile Minisart® Ophthalsart syringe filters are optimal for immediate usage whenever sterile filtration or clarification under sterile conditions is needed. The SFCA membrane is the best option for leachable free filtrations. The very low non-specific binding characteristics of this membrane makes it a perfect choice for biomolecule solutions. The housing is made of the acrylic resin MBS (Methacrylate butadiene styrene) which has a limited compatibility with alcohols but is free of phthalates and passes the plastic class VI test. Housing and membrane are tightly connected which allows bidirectional use. Sterile and ready-to-use SFCA in many pore sizes Very low non-specific binding PVC-free Bidirectional use possible
