Pura Disc 25mm Nylon Syringe Filters, 1.0um, 50 Pk
Whatman SKU: 6750-2510

Whatman Puradisc Nylon Syringe Filters, 1 µm, 25 mm, 50/Pk - 6750-2510

Whatman standardizes its manufacturing platform to the point that consistency and thorough lot-level records come as a default, exactly what analytical laboratory work demands. Because each syringe filter is dedicated to one sample, a failed or contaminated filtration never delays the next analyst's run waiting on a shared holder. The nylon membrane draws aqueous buffers without pre-wetting while holding dimensional stability under rated backpressure and supports high-volume routine filtration. The PP housing stays inert across common laboratory solvents and buffers in routine use and sustains efficient flow on viscous samples. For routine sample preparation across many methods, each analytical run starts with a consistent, particle-free sample without added hardware or a cleaning step.

Membrane Characteristics

• Ester- and alcohol-resistant across common laboratory sample preparations
• Resonance-stabilized amide bonds anchor nylon's resistance to alkaline hydrolysis
• Autoclaving at 121°C for 30 minutes leaves pore structure intact
• Non-fibrous membrane structure resists media shedding into the filtrate
• Compatible with most HPLC mobile phases for sample clarification

Housing Characteristics

• Housing retains dimensional stability and seal integrity through elevated-temperature operation up to 121°C.
• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Rigid polypropylene body maintains its geometry through routine filtration pressure

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows. Bulk pricing kicks in on larger filtration orders, so ask the Tisch Scientific team for a quote.

• HPLC Pump Protection - Filters reservoir solvent to prevent particulates from abrading pump check valves and seals over time.
• Capillary Electrophoresis Prep - Delivers low background noise in small-format CE filtration for high-resolution separations and accurate data.
• GC Sample Prep - Clarifies aqueous and organic extracts ahead of gas chromatography injection, protecting inlets from particulate fouling.
• Environmental Extract Prep - Clarifies water and soil extracts ahead of trace metals or pesticide-residue analysis for accurate results.
• HPLC Sample Prep - Clarifies mixed aqueous and organic solvents to ensure stable baselines and protect chromatography columns from clogging.
• Ink and Dye Filtration - Filters aqueous and solvent-based inks and dyes, removing pigment agglomerates ahead of color strength analysis.
