Whatman
GD/X 13mm Syringe Filter, PTFE Filteration Medium, 0.45um (150 pcs) SKU: 6874-1304

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 13mm - 6874-1304

Designed to protect sensitive chromatography columns from clogging, the Polytetrafluoroethylene (PTFE) Whatman GD/X 13mm Syringe Filter, PTFE filtrationmedium, 0.45µm, 150/pk delivers exceptional retention of particulates without compromising flow rates. To ensure analytical precision, the unit is constructed with a high-grade Polytetrafluoroethylene (PTFE) membrane providing a consistent 0.45 cutoff that passes only your target analyte. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

Hydrophobic

• Aggressive Solvent Filtration - PTFE is chemically inert, making it the only choice for filtering strong acids and bases
• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Sample Clarification - Protecting analytical instruments via rapid removal of particulates to maintain high throughput in busy laboratories
• Biological Fluid Analysis - Protects sensitive downstream instruments from removing particulates that can cause system failure
