Whatman
GD/X 25mm Syringe Filter, PTFE Filteration Medium, 0.45um (1500 pcs) SKU: 6875-2504

GF/PTFE Syringe Filters, 0.45µm, 25mm - 6875-2504

In high-throughput analytical laboratories, the GF/PTFE Whatman GD/X 25mm Syringe Filter, PTFE filtrationmedium, 0.45µm, 150/pk series establishes a standard for effective particulate removal and sample clarification. To ensure analytical precision, the unit is constructed with a high-grade GF/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. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

Key GF/PTFE Membrane Characteristics

• GF/PTFE membrane with hydrophobic (requires pre-wetting) or hydrophilic (if treated) affinity
• Low Protein Binding characteristics
• Extreme chemical resistance to aggressive solvents, acids, and bases
• Hydrophobic version acts as an effective moisture barrier
• Verified 0.45 retention rating for clarification

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lok/ Luer Slip for secure fitting
• 4.6cm² effective filtration area
• 1400 µL holdup volume to minimize sample loss

You can streamline your sample preparation process significantly by adopting a filtration solution designed to handle your specific volume requirements. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.

Hydrophobic

• 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
• 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
• General Laboratory Filtration - Increases workflow efficiency by protecting analytical instruments without sacrificing flow rates
• Research & Development - Supports protocols that need to remove particulates, providing the ability to protect analytical instruments
