Disposable syringe filters are a fast, convenient and reliable filtration tool for routine laboratory use. They attach to the end of a disposable syringe and are used for sample pre-filtration, particulate clarification, and sterilizing filtration of liquids and gases. They protect HPLC and GC columns and instruments from clogging, and they are the preferred method for small-volume sample pre-filtration in HPLC and GC. There is no membrane replacement and no filter cleaning, so sample preparation is quick and simple.→ View all Syringe Filters

Non-sterile (N): for routine sample clarification before HPLC/GC and general lab filtration.Sterile (S): sterilized by EO (ethylene oxide) or Gamma irradiation, for sterilizing filtration of biological and pharmaceutical samples. Our StarTech™ sterile filters come in individual sterile blister packs, in 13 mm and 33 mm sizes, with 0.22 or 0.45 µm pore size, low hold-up volume and low extractables.→ Syringe Filters

Hydrophilic membranes (marked "I" in our part numbers) wet easily and are used for aqueous solutions. Hydrophobic membranes (marked "O"), such as PTFE, repel water and are used for organic solvents, aggressive chemicals, and for filtering air and gases.→ Syringe Filters | Air/Vent Filters

Yes. Our Automated Certified Syringe Filters are designed for HPLC and UPLC automated sample processing. They offer high flow rates with multilayer membranes, two to four times the throughput of standard glass fiber prefilter devices, better column protection, and compatibility with SOTAX and Zymark automated test systems.→ Syringe Filters

Yes. Our reusable 316 stainless steel syringe filter holders come in 13, 25 and 47 mm (filtration area 1.3, 3.9 and 13.8 cm²). They are affordable, environmentally friendly, easy to clean, and let you recover residues from the membrane. We also offer autoclavable polypropylene holders (Luer slip, up to 2 bar, 20 min at 121°C).→ Reusable Stainless Steel Syringe Filters
