High-Performance Syringe Filters: Protect Your Column, Purify Your Results
In analytical chemistry, the smallest particle can lead to the biggest downtime. Our premium Syringe Filters are the first line of defense for your HPLC, UHPLC, and GC systems, removing particulates that cause backpressure spikes, column clogging, and detector noise.
Whether you are performing routine environmental testing or complex protein purification, our filters ensure sample integrity without introducing extractables or leachable contaminants.
Engineered for Every Matrix: Membrane Selection Guide
Choosing the right membrane is critical to avoiding sample loss or chemical interference. We stock a comprehensive range of diameters (13mm, 25mm, 33mm) and pore sizes (0.22µm and 0.45µm).
1. Nylon Syringe Filters
Best For: Bases, HPLC solvents, alcohols, and aromatic hydrocarbons.
Key Feature: Naturally hydrophilic with high mechanical strength.
Note: Not recommended for strong acids or protein samples due to high binding.
2. PTFE (Polytetrafluoroethylene) Filters
Best For: Aggressive organic solvents, highly acidic/basic samples, and gas filtration.
Hydrophobic version: Ideal for venting and organic solvent filtration.
Hydrophilic version: Versatile for both aqueous and organic “universal” filtration.
3. PES (Polyethersulfone) Filters
Best For: Biological samples, tissue culture media, and pharmaceutical filtration.
Key Feature: Extremely low protein binding and high flow rates.
4. PVDF (Polyvinylidene Difluoride) Filters
Best For: General biological samples and HPLC sample prep.
Key Feature: High solvent resistance and very low protein adsorption.

Why Our Syringe Filters Lead the Industry
HPLC Certified: Every batch is tested for low extractables to ensure no “ghost peaks” appear in your chromatograms.
Ultrasonic Bonding: Our housings are ultrasonically welded, never glued, to prevent adhesive contamination and ensure high-pressure integrity.
Color-Coded Housing: Instantly identify membrane type and pore size at the bench, reducing the risk of laboratory error.
Universal Luer-Lok: Securely fits all standard syringes to prevent high-pressure leaks or “pop-offs.”
Optimize Your Workflow: Best Practices
Pro Tip: Always “discard” the first 1ml of filtered sample. This saturates the membrane and ensures the aliquot you collect is truly representative of your original sample concentration.
