Sterile PVDF Syringe Filters, Choose Size, pack/100

Sterile PVDF Syringe Filters. We provide HPLC Certified, high quality and cost-effective syringe filters. These polyvinylidene difluoride (PVDF) syringe filters are available in two different porosities (0.45 µm and 0.22 µm) and two diameters (25mm and 13mm.)

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 - Polyvinylidene Difluoride (PVDF) - Hydrophobic

• This membrane features a stability and hydrophobic interactions similar to PTFE
• Recommended especially for filtration of water-soluble oligomers and polymers, e.g. protein solutions
• Can also be used for the filtration of hydrophobic substances in different organic solvents
