Tisch Scientific Polyethersulfone (PES) Syringe Filters, 0.22 µm, 4 mm - SF18206

Tisch Scientific's product lineup extends from filtration membranes to devices and the consumable supplies laboratories use daily. At the sub-micron pore rating, a syringe filter delivers sterilizing-grade retention at the point of use. PES handles strong bases and oils across a broad aqueous range while needing a surface treatment before its polysulfone base wets and pairs fast flow with reduced protein adsorption. The polypropylene housing presses snugly against the membrane during the pass while keeping sample purity intact through the filtration pass and resists degradation from routine sample matrices. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• Finest available pore ratings achieve aseptic-grade filtration performance
• Absolute pore size rating holds consistent across every lot
• Non-ionic surface avoids charge-driven protein binding of positively and negatively charged membrane types
• Sterilizing-grade PES membrane lots are challenge-tested against Brevundimonas diminuta to qualify 0.2 micron retention
• Non-hydrogen-bonding surface avoids the polar adsorption nylon's amide backbone causes

Housing Characteristics

• Impact-tolerant polypropylene body withstands routine bench handling without damage
• The seal formed against the membrane blocks bypass at rated operating pressure
• Medical-grade polypropylene with broad chemical compatibility
• Rigid polypropylene body maintains its geometry through routine filtration pressure

Unfiltered particulates shift your retention times and peak shapes from run to run. Pre-injection filtration protects the resolution your methods depend on by clearing particulates ahead of the column and frits.

• Organic Carbon Testing - Clarifies water samples ahead of DOC and UV254 analysis while keeping organic carbon adsorption to the membrane minimal.
• Biological Assays - Protects sensitive enzymatic and antibody-based assays from particulate interference without adsorbing critical reagents.
• Cell Culture - Reduces the risk of mycoplasma contamination in growth media, supporting healthier cell lines and more reliable experimental outcomes.
• Pesticide Residue Testing - PES membranes improve polar pesticide recovery in food-safety LC-MS/MS testing versus hydrogen-bonding nylon.
• Urine Drug Screening - Clarifies protein-poor urine samples for dilute-and-shoot LC-MS/MS toxicology testing without adsorbing target drug analytes.
• Sample Recovery - Minimizes sample loss in low-protein-binding applications, delivering high yield for precious or rare biological specimens.
