Whatman
Pura Disc 25mm PTFE Syringe Filters, 0.1um, 50 Pk SKU: 6784-2501

Polytetrafluoroethylene (PTFE) Syringe Filters, 0.1µm, 25mm - 6784-2501

Eliminate the risk of microbial contamination in your upstream workflows with the Polytetrafluoroethylene (PTFE) Whatman Puradisc, 25mm, Syringe Filter, 0.1µm, nonsterile 50/pk, optimized for sterile filtration protocols. To achieve this medical-grade standard, the filter utilizes a Polytetrafluoroethylene (PTFE) membrane that provides a sharp 0.1 cutoff necessary for sterilizing biological fluids. To guarantee structural reliability, each unit undergoes strict quality control to ensure the housing and membrane seal withstand standard operating pressures without leakage. 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
• 0.1 rating suitable for sterile filtration

Key Housing Characteristics

• High-purity Polypropylene encapsulation housing
• Luer-Lok/ Luer Slip for secure fitting
• 4.2cm² effective filtration area
• <100µl holdup volume to minimize sample loss

When you integrate these filters into your daily standard operating procedures, you are choosing a workflow that prioritizes efficiency without compromising results. You can rely on the certified integrity of these units to protect your critical samples and instrumentation from damaging contaminants. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

Hydrophobic

• Aerosol Sampling - The hydrophobic nature of PTFE allows for gas venting and air monitoring applications in harsh environments
• 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
• Cryogenic Fluids - Remains functional and integral even at extreme temperatures, protecting sensitive equipment from damage
• Research & Development - Supports protocols that need to eliminate mycoplasma, providing the ability to prevent culture contamination
• Quality Control Testing - Optimized for Delivering reproducible results by eliminating mycoplasma in standard pharmaceutical protocols
