Tri-Layer Non-sterile Syringe Filters, PP/GF Prefilter, 25mm, pack/100

We offer HPLC Certified, high quality and cost effective syringe filters. These 25mm diameter non-sterile nylon syringe filters are available in packs of 100 and in 0.45 µm and 0.22 µm porosity.

Features

• Disposable
• Luer-Lock; and pressure fitting
• Ultrasonically bonded for reliability
• Filter media type clearly inscribed on barrel
• Excellent unit-to-unit and lot-to-lot reproducibility and consistency
• High purity virgin polypropylene housing, no dyes or pigments added
• Every unit type is available as an individually wrapped gamma sterilized pack
• Unique concentric funnel shaped barrel increases volume and decreases back pressure

Simple Product Selection

1. Evaluate sample: Determine chemical compatibility, volume and need for prefiltration
2. Determine level of prefiltration necessary: In filter unit vs. prefilter unit in series for coarse precipitants.
3. Choose filter media type: Aqueous: Nylon, MCE, CA or Non-polar: Nylon, PTFE, PVDF or Protein: PVDF, PES
4. Choose barrel diameter: 10 mL: 13 mm diameter or 100 mL: 25 mm diameter
5. Choose initial or secondary retention target: 0.45 µm or 0.20 µm

Applications - Polyamide/Nylon PA - Hydrophilic

• Hydrophilic material; it is recommended for filtration of aqueous or organic/aqueous medium polar liquids
• Commonly used for general laboratory filtration and filtration of HPLC and GC samples prior to injection
• Filtration of aqueous and organic-aqueous polar medium liquids
• Dissolution sample analysis
• Suitable for use with high pH samples
• Since it binds proteins it is NOT suitable for protein recovery applications
• With microfiber prefilter higher absorption capacity for contamination
