Membrane Solutions Sterile PES Syringe Filters, Hydrophilic 0.22µm 33mm — Individually Packed 10-Pack

Product overview Sterile PES syringe filters (33 mm, 0.22 µm) for reliable liquid sample clarification and protection of downstream instruments. Designed for low protein binding, high flow rates, and consistent particle retention — ideal for buffers, protein solutions, culture media, additives and general laboratory sample filtration.

Key benefits - Assures sample purity and protects HPLC/UHPLC columns and analytical equipment.
- Low protein adsorption preserves sample integrity for protein and bioassay applications.
- High dirt-holding capacity (GF pre-filter option) extends throughput for “hard-to-filter” samples.
- Consistent, uniform pore structure delivers reproducible filtration and reliable results.
- ISO 9001 certified manufacturing ensures consistent quality and traceability.

Features - Membrane: Sterile Polyethersulfone (PES), hydrophilic microporous membrane for high flow and very low protein binding.
- Housing: Durable polypropylene (PP) construction for chemical compatibility and leak-free performance.
- Pre-filter: Glass fiber (GF) pre-filter option for enhanced particulate load capacity.
- Pore size & size: 0.22 µm pore size, 33 mm diameter — common choice for sterile filtration and particle removal.
- Sterility: Supplied sterile via irradiation processing.
- Shelf life: 5-year shelf life from manufacture (check batch code on package for exact expiration date).
- Quality: Manufactured with threaded interface design and ISO 9001 quality management.

Applications - Filtration of buffers, mobile phases and sample preparation for HPLC/LC-MS.
- Clarification of protein solutions, culture media and biological reagents.
- Removal of particulates prior to sterile dispensing, cell culture, or analytical testing.
- General laboratory sample cleanup where low protein binding and high flow are required.

Usage notes - Supplied sterile; not suitable for re-sterilization.
- Choose 0.22 µm for sterilizing-grade particle removal; GF pre-filter recommended for high particulate or viscous samples.
