Minisart® NML Syringe Filters

Sterile filtration and particle removal

Sterilization by filtration is the fastest solution for bacteria removal from liquids. Minisart^® NML with surfactant-free cellulose acetate [(SF)CA] is the best choice for all aqueous solutions with a pH of 4 – 8. It combines fast flow rates and is available in many different pore sizes for removal of larger particles. Minisart^® High Flow with polyethersulfone (PES) is optimal for high flow rates and a pH of 1 – 13. Both Minisart^® types are available pre-sterilized by ethylene oxide (EO) or gamma irradiation. Hydrophobic PTFE filters like Minisart^® SRP are suitable for venting purposes and are available with activated carbon.

¹ See Technical Specs for details on membrane types

² Hydrophobic membranes cannot be wetted with aqueous solutions unless water penetration point is exceeded or pre-wetted with organic solvent.

³ For sterile packs (K or GUK)

⁴ According to bacterial challenge test (BCT) with ≥ 1 × 10⁷ cfu/cm² Brevundimonas diminuta. Non-sterile RC Minisart® types are optimized for sample preparation and are not suitable for sterile filtration according to the BCT. All other non-sterile Minisart® types with 0.2 μm pore size can be sterilized by autoclaving or EO before use for sterile filtration.
