GD/X 25mm 5.0um Syringe Filter, NYL
Whatman SKU: 6871-2550

Whatman GD/X Nylon Syringe Filters, 5 µm, 25 mm, 150/Pk - 6871-2550

Whatman applies the same process controls across its filtration portfolio, verifying rated performance at the production lot level. Syringe filters mount on a syringe to clarify a sample in a single manual pass. The nylon matrix resists particle shedding through extended filtration cycles and resists alkaline buffer systems. The polypropylene housing routes flow to minimize backpressure in service and contributes minimal extractables to the filtrate. When method reproducibility rests on consistent sample prep, syringe filtration holds that standard injection after injection.

Technical Specifications

• Non-sterile for routine clarification and sample prep
• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• Naturally hydrophilic surface wets without pre-wetting in aqueous applications
• Alkaline-resistant across a broad range of aqueous buffers
• Low extractable contribution to sensitive analytical preparations

Housing Specifications

• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Medical-grade polypropylene with broad chemical compatibility
• Low extractable contribution protects sensitive downstream analyses
• Resists aqueous acids, bases, and alcohols in routine sample prep

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. General-purpose aqueous filtration supports the sample types you handle every day so you can standardize one filter across most aqueous methods. Connect with our customer support technicians for chemical compatibility guidance and the right filtration product for your workflow.

• Dissolution Testing - Nylon is the industry standard for automating dissolution workflows due to its broad solvent compatibility
• HPLC Sample Preparation - Optimized for the high-strength Nylon membrane, which is ideal for clarifying basic and neutral mobile phases
• Chemical Filtration - Excellent resistance to esters, bases, and alcohols makes Nylon the go-to choice for composite chemical streams
• Sample Clarification - Protecting upstream systems via rapid clearing of gross precipitates to maintain high throughput in busy laboratories
• Particulate Removal - Designed for clearing gross precipitates, this filter aids in protecting upstream systems across diverse sample types
• Research & Development - Supports protocols that need to clear gross precipitates, providing the ability to protect upstream systems
