Whatman
GD/X 25mm Syringe Filter, PTFE Filteration Medium, 0.2um (1500 pcs) SKU: 6875-2502

GF/PTFE Syringe Filters, 0.2µm, 25mm - 6875-2502

Eliminate the risk of microbial contamination in your upstream workflows with the GF/PTFE Whatman GD/X 25mm Syringe Filter, PTFE filtrationmedium, 0.2µm, 150/pk, optimized for sterile filtration protocols. To achieve this medical-grade standard, the filter utilizes a GF/PTFE membrane that provides a sharp 0.2 cutoff necessary for sterilizing biological fluids. 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 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 0.2 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

Your laboratory throughput depends on reliable consumables, and these filters are designed to keep your sequences running smoothly, sample after sample. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.

Hydrophobic

• 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
• Aggressive Solvent Filtration - PTFE is chemically inert, making it the only choice for filtering strong acids and bases
• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Particulate Removal - Designed for filtering contaminants, this filter aids in optimizing sample clarity across diverse sample types
• Sample Clarification - Optimizing sample clarity via rapid filtering of contaminants to maintain high throughput in busy laboratories
