Nylon Syringe Filters w/ GD-4 Pre-Filter, 0.22um, 25mm, Nonsterile, 100/Pk SKU: GD17033

Nylon Syringe Filters - GD17033

Featuring naturally hydrophilic nylon membrane technology with an integrated GD-4 multi-layer prefiltration system for superior sterilization performance and extended filter life. The GD17033 combines certified 0.22µm sterile filtration with graded-density prefilters that capture particles progressively, preventing premature membrane clogging. Tisch Scientific syringe filters incorporate robust polypropylene housing engineered to withstand 87psi operating pressure while the four-layer design maintains consistent flow rates during challenging sterilization procedures.

Key Nylon Membrane Characteristics

• Naturally hydrophilic membrane provides immediate wettability without pre-treatment for efficient sterilization
• Certified 0.22µm final filtration ensures complete bacterial retention, meeting sterilization requirements
• GD-4 graded-density prefilter layers extend membrane life by capturing particles sequentially
• Excellent chemical compatibility supports both aqueous non-acidic and organic solvent sterilization
• Multi-layer construction maintains an 8ml/minute flow rate even with particulate-laden samples

Key Construction Characteristics

• Four-layer GD-4 prefiltration design prevents premature membrane fouling during sterile processing
• Chemical-resistant polypropylene housing withstands 87psi burst pressure, ensuring sterile integrity
• Universal Luer-Lok/Luer Slip connections guarantee compatibility with standard laboratory syringes
• Enhanced filtration capacity processes heavily contaminated samples, requiring sterilization

GD17033 syringe filters deliver exceptional sterilization performance through innovative multi-layer prefiltration that significantly extends filter life with challenging samples. Your laboratory achieves reliable sterile filtration even with particulate-laden matrices that would rapidly clog standard 0.22µm filters, optimizing both sterility assurance and operational efficiency.
