What Stands Out
High Purity
Crafted from hydrophilic PTFE material, these filters ensure minimal leaching and contamination, making them ideal for sensitive applications in labs and industrial settings.
Optimized Filtration
With a precise 0.45um pore size, these discs effectively remove particulates and microorganisms, ensuring high clarity in liquids and meeting stringent filtration standards.
Convenient Packaging
Sold in packs of 100, these 47mm membrane discs offer great value and convenience, allowing users to conduct multiple experiments without frequent reordering.

Who Should Buy?
-
Laboratory Technicians
Ideal for filtration in research and quality control applications, providing reliable solutions for pure sample preparation.
-
Water Quality Testing
Perfect for filtering water samples in environmental monitoring, ensuring accurate analysis of contaminants and impurities.
-
Biological Applications
Useful for sterilizing biological fluids and media, ensuring the removal of bacteria and maintaining sample integrity.
-
Heavy Solvent Use
Not suitable for filtering aggressive solvents as PTFE may degrade under certain chemical exposures.
-
High Volume Filtration
May not be efficient for large-scale applications due to the limited size and pore capacity of each disc.
-
Non-Hydrophilic Scenarios
Not recommended for hydrophobic applications since the nature of PTFE is suited for hydrophilic solutions only.

Customer Questions & Answers
-
Question:
What is a PTFE membrane disc filter and what is it used for?
Answer: A PTFE membrane disc filter is a porous filter made from polytetrafluoroethylene, designed to separate particles from liquids or gases. With a pore size of 0.22 micrometers, it is particularly effective in filtering out bacteria and other microorganisms. These filters are commonly used in laboratories, pharmaceuticals, and environmental monitoring to ensure sample integrity by preventing contamination. -
Question:
What are the benefits of using hydrophobic filters?
Answer: Hydrophobic filters repel water, making them ideal for filtering non-aqueous solutions and preventing liquid from passing through while allowing gases to flow. This quality is crucial for applications where moisture can compromise sample integrity or lead to contamination. Use cases include air sampling in microbiological studies or filter sterilization of organic solvents in chemical analysis. -
Question:
How do I select the correct pore size for my application?
Answer: Choosing the right pore size depends on your specific filtration needs. For instance, a pore size of 0.22um is suitable for retaining bacteria while allowing viruses and smaller particles to pass through. It’s essential to consider the characteristics of the solution or gas you are filtering; a greater pore size may be suitable for larger particulates, while smaller sizes are needed for finer filtration. -
Question:
Can these filters be reused?
Answer: Generally, PTFE membrane disc filters are designed for single-use applications to maintain sample purity and prevent cross-contamination. However, in certain low-risk scenarios, they can be rinsed and reused if they show no signs of clogging or damage. Always assess the filter after use to ensure it performs adequately before considering reuse. -
Question:
Are these filters resistant to aggressive solvents?
Answer: Yes, PTFE filters are highly resistant to a variety of chemicals, including aggressive solvents, acids, and bases, making them suitable for diverse laboratory applications. Their chemical resistance enhances the integrity of sensitive analysis, allowing for reliable results when filtering samples that are chemically reactive. -
Question:
How do I store PTFE membrane disc filters?
Answer: PTFE membrane disc filters should be stored in a cool, dry place, in their original packaging, to protect them from contamination and damage. Avoid exposing them to direct sunlight or high humidity conditions to maintain their integrity. Proper storage ensures that the filters remain usable for future applications. -
Question:
What are common applications of the 47mm PTFE membrane disc filter?
Answer: 47mm PTFE membrane disc filters are widely used in laboratory settings for sterilizing media, air sampling, and clarifying solutions. Their size and hydrophobic nature make them suitable for filtering aqueous and non-aqueous solutions, providing versatility in biological and chemical research applications. -
Question:
Are the filters compatible with syringe-loading methods?
Answer: Yes, these filters are designed for compatibility with syringe-loading methods, making them practical for single-use applications. Using a syringe for filtration ensures ease and precision, allowing for quick and effective filtering without the risk of contamination from multiple uses. -
Question:
Can I use these filters for air filtration?
Answer: Absolutely! PTFE membrane disc filters are excellent for air filtration applications, thanks to their hydrophobic nature. They effectively trap particulates and microorganisms while allowing gases to pass through, making them ideal for use in air quality testing and microbiological studies to ensure clean air samples. -
Question:
Where can I buy 100PCS PTFE Membrane Disc Filter, Hydrophobic, 47mm, Micron Pore Size 0.22um in Saint Helena?
