Whatman
GD/XP Syringe Filter, PTFE Filteration Medium, 0.45um (150 pcs) SKU: 6974-2504

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 25mm - 6974-2504

Reducing background noise in analytical assays begins with proper clarification, and the Polytetrafluoroethylene (PTFE) Whatman GD/XP Syringe Filter, PTFE filtrationmedium, 0.45µm, 150/pk is engineered to remove interfering solids efficiently. Driving this clarification performance is a hydrophobic Polytetrafluoroethylene (PTFE) membrane featuring a verified 0.45 pore structure that captures target particulates while minimizing holdup volume. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. Consequently, by reducing the risk of downstream contamination, these filters serve as a critical safeguard for the integrity of your experimental results.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Polytetrafluoroethylene (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. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Aggressive Solvent Filtration - PTFE is chemically inert, making it the only choice for filtering strong acids and bases
• 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
• Quality Control Testing - Optimized for delivering reproducible results by removing particulates in standard pharmaceutical protocols
