Whatman
Pura Disc 13mm PTFE Syringe Filters, 0.45um, 2000 Pk SKU: 6766-1304

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.45µm, 13mm - 6766-1304

Designed to protect sensitive chromatography columns from clogging, the Polytetrafluoroethylene (PTFE) Whatman Puradisc, 13mm, Syringe Filter, 0.45µm, nonsterile (2000 pcs) delivers exceptional retention of particulates without compromising flow rates. Driving this clarification performance is a hydrophobic Polytetrafluoroethylene (PTFE) membrane featuring a verified 0.45 pore structure that captures target particulates while minimizing holdup volume. 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 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 Polypropylene encapsulation housing
• Luer-Lok/ Luer Slip for secure fitting
• 1.3cm² effective filtration area
• <25µl holdup volume to minimize sample loss

By selecting a filter that matches the exact chemical nature of your samples, you ensure that your workflow remains uninterrupted by membrane failures. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Hydrophobic

• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• 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
• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• General Laboratory Filtration - Increases workflow efficiency by protecting analytical instruments without sacrificing flow rates
• Analytical Sample Prep - Optimized to ensure data integrity by effectively removing particulates before instrumental analysis
