Minisart® PP Syringe Filters

Minisart® PP Syringe Filters

Sample prep for HPLC & analytics

Particle removal prior to analytics greatly increases the lifetime of your HPLC columns. Minisart® RC uses regenerated cellulose filters that are optimized for aqueous liquids as well as solvents. They are stable against DMSO, other amides, ketones, esters and ethers. Minisart® NY has exceptionally pure polyamide (nylon) membranes that do not interfere with standard analytical methods. The coating-free hydrophobic PTFE membrane used in Minisart® SRP is suitable for venting applications. The Minisart® PES (polyethersulfone) filters are available for aqueous filtration as well as for gas filtration and venting with the PES- coated hydrophobic filters.

1 Performance specs for RC 0.2 µm ACK (sterilized) are different. See Minisart brochure for details.

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

3 PES is suitable for only containing up to 30% methanol.

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.
