RephiQuik 0.22 uM Syringe Filters

PTFE, PVDF, PES & Nylon Membranes – Non-Sterile.

RephiQuik 0.22 uM Non-sterile Syringe Filters are precision-engineered for fine filtration and sterilization of aqueous, organic, or protein-based solutions in laboratory workflows. Designed for high performance with low extractables, these filters feature four membrane options—PTFE, PVDF, PES, and Nylon—to meet the diverse needs of analytical and research applications.

Each filter is constructed with a durable polypropylene (PP) housing and includes a female luer-lock inlet with a male luer-slip outlet for secure, leak-free operation. The 0.22 uM pore size enables efficient removal of bacteria and fine particulates, ensuring clarity, sterility, and protection of downstream systems such as HPLC instruments and cell cultures.

The filters offer a large effective filtration area with minimal hold-up volume, ensuring maximum recovery of precious samples. The membrane type and pore size are clearly printed on each unit, and color-coded housings provide quick visual identification: blue (PTFE), yellow (PVDF), green (PES), and purple (Nylon).

Membrane Options & Applications

• PTFE (Polytetrafluoroethylene)
• Hydrophobic membrane for highly aggressive solvents, strong acids, and gases. Excellent for chemical compatibility in HPLC and air filtration.
• PVDF (Polyvinylidene fluoride)
• Hydrophilic, low protein binding. Ideal for filtration of protein solutions, biological samples, and molecular biology workflows.
• PES (Polyethersulfone)
• Hydrophilic with asymmetric structure for rapid filtration of aqueous and slightly organic solutions. Optimized for cell culture and sterilization of buffers.
• Nylon
• Hydrophilic, chemically resistant to a wide range of solvents including ACN, DMF, and DMSO. Suitable for aqueous and organic sample filtration. 

Key Features

• Pore Size: 0.22 uM – ideal for sterilizing filtration
