Hydrophilic PTFE Syringe Filters
Description
Hydrophilic PTFE syringe filters are high-performance membrane filters designed for direct filtration of aqueous and organic solutions without pre-wetting. Hawach provides a structured three-series system—Disposable, Standard, and Sterile—to support laboratory, analytical, and pharmaceutical-grade applications.
These filters combine excellent chemical resistance, low extractables, and high flow efficiency, making them suitable for HPLC, UHPLC, and a wide range of laboratory workflows.
Hydrophilic PTFE Syringe Filters for Different Laboratory Needs
Hydrophilic PTFE syringe filters are designed to match different laboratory workflows based on accuracy, sterility, and cost requirements:
- Routine laboratory filtration → Disposable PTFE Series
- HPLC / UHPLC / analytical testing → Hawach Standard PTFE Series
- Pharmaceutical / biotech / sterile processing → Sterile PTFE Series
Product Series Architecture
Core Analytical Series: Hawach Standard PTFE Syringe Filters are the primary recommendation for HPLC and laboratory analysis due to their balanced performance and low extractables.
Routine Use Series: Disposable PTFE Syringe Filters provide economical and stable performance for everyday filtration tasks.
High-Purity Series: Sterile PTFE Syringe Filters are designed for aseptic pharmaceutical and biotech applications requiring strict contamination control.
Recommended Choice for Most Laboratories
For most analytical laboratories, Hawach Standard Hydrophilic PTFE Syringe Filters are the preferred choice due to their balanced performance, low extractables, and compatibility with HPLC and UHPLC workflows.

Optimized for HPLC and UHPLC Sample Preparation
Hydrophilic PTFE syringe filters are widely used in HPLC and UHPLC workflows due to their low extractables, high chemical resistance, and stable filtration performance. They help ensure clean chromatographic baselines and reliable analytical results.
- Low extractables for interference-free analysis
- Compatible with common HPLC solvents
- Reduces baseline noise and contamination risk
Why Choose PTFE Syringe Filters Over Other Membranes?
Compared with nylon, PES, and PVDF membranes, PTFE provides the widest chemical compatibility and is the preferred choice for aggressive solvents and complex analytical applications.
- Superior chemical resistance to acids and solvents
- Stable performance in extreme environments
- Lower risk of membrane degradation
Key Applications
- HPLC / UHPLC sample preparation
- Pharmaceutical quality control
- Environmental water analysis
- Strong acid and solvent filtration
- Biochemical and life science research
