Whatman
ReZist Syringe Filter, 30mm, PTFE, 0.45um, 100/Pk SKU: 10463513

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 13mm - 10463513

Designed to protect sensitive chromatography columns from clogging, the Polytetrafluoroethylene (PTFE) Whatman Puradisc 13mm Syringe Filter, 0.45µm, nonsterile, 100/pk delivers exceptional retention of particulates without compromising flow rates. 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. Designed to facilitate rapid processing, the housing features an optimized flow geometry that minimizes backpressure, allowing for easier manual filtration even with viscous samples. Ultimately, this rigorous attention to manufacturing quality ensures batch-to-batch reproducibility, allowing laboratories to standardize their workflows with total confidence.

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 nan encapsulation housing
• Luer-Lok/ Luer Slip for secure fitting
• 1.33cm² effective filtration area
• nan holdup volume to minimize sample loss

Hydrophobic

• Organic Mobile Phases - Ideal for filtering 100% organic solvents in HPLC and GC workflows without any membrane degradation
• Aggressive Solvent Filtration - PTFE is chemically inert, making it the only choice for filtering strong acids and bases
• 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
• Analytical Sample Prep - Optimized to ensure data integrity by effectively removing particulates before instrumental analysis
• Biological Fluid Analysis - Protects sensitive downstream instruments from removing particulates that can cause system failure
