LabExact PTFE Syringe Filters, 0.22 µm, 13 mm, 100/Pk - LE-IWT-ES10039

A sterilizing-grade syringe filter carries manufacturer bacterial retention testing built into the design, giving analysts documented sterile-grade performance without repeating that testing in-house for the format. PTFE suits solvent and reagent filtration where other membranes fail while delivering sterilizing-grade liquid retention at sub-micron pore sizes and resists attack from the harshest process chemistries. The PP housing stays inert across common laboratory solvents and buffers in routine use while shedding virtually no extractable material into the sample and sustains efficient flow on viscous samples. For workflows requiring validated sterile-grade performance, point-of-use retention meets it without a separate sterilization step.

Membrane Characteristics

• UL 94 V-0 rating confirms the highest self-extinguishing classification
• Low non-specific protein binding preserves recovery of biomolecules and therapeutic proteins during filtration
• Biological inertness resists enzymatic attack from proteases and lipases
• Absolute pore rating delivers reproducible retention across every protocol
• Validated against a liquid suspension Brevundimonas diminuta challenge at 10 million CFU per square centimeter

Housing Characteristics

• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• Thermal-bonded construction keeps adhesives out of the fluid path
• Plasticizer-free polyolefin construction keeps the fluid path clean

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.
