PTFE Membrane Filter, Hydrophobic, 1.0um, 55mm, For EPA Method OTM 28 (Method 5 w/ 202), 50/Pk SKU: SF17940

Polytetrafluoroethylene (PTFE) Membrane Filters, 1.0µm, 55mm - SF17940

Reducing background noise in analytical assays begins with proper clarification, and the Polytetrafluoroethylene (PTFE) Membrane Filters, 1.0um, 55mm, Nonsterile, 50/pk is engineered to remove interfering solids efficiently. Driving this clarification performance is a hydrophobic Polytetrafluoroethylene (PTFE) membrane featuring a verified 1.0 pore structure that captures target particulates while minimizing holdup volume. Manufactured with strict thickness tolerances, these membranes provide a reliable barrier for critical filtration steps without compromising flow. 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 (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 1.0 retention rating for clarification

When you integrate these filters into your daily standard operating procedures, you are choosing a workflow that prioritizes efficiency without compromising results. You invest significant resources into your samples; safeguarding them with a proven filtration barrier is a cost-effective insurance policy for your lab. 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.
