Acro Disc Syringe Filters w/ PTFE Membrane - 0.45um, 13mm, Minispike Outlet, 1000/Pk SKU: 4555

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 13mm - 4555

Reducing background noise in analytical assays begins with proper clarification, and the Polytetrafluoroethylene (PTFE) Syringe Filters is engineered to remove interfering solids efficiently. To ensure analytical precision, the unit is constructed with a high-grade Polytetrafluoroethylene (PTFE) membrane providing a consistent 0.45 cutoff that passes only your target analyte. Encasing this critical media is a high-purity polypropylene housing that prevents sample bypass and ensures that every microliter is processed with high fidelity. The result is a filtration solution manufactured in an ISO-certified facility that minimizes distinct interference, providing clean baselines for publication-quality data.

Key Polytetrafluoroethylene (PTFE) Membrane Characteristics

• Polytetrafluoroethylene (PTFE) membrane with hydrophobic (standard) / hydrophilic (treated) affinity
• Chemically Inert characteristics
• Universal resistance to aggressive organic solvents, strong acids, and alkalis
• Hydrophobic version requires alcohol pre-wetting for aqueous solutions
• Verified 0.45 retention rating for clarification

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lock/ Minispike for secure fitting
• 1.0cm² effective filtration area
• < 30 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. Make the decision for consistency and reliability, ensuring that your laboratory maintains its reputation for high-quality, error-free output.
