Product Description
When precision and reliability matter in lab filtration, the PTFE membrane (6-10 micron) from Thermo Fisher stands out as a top choice. Engineered for exceptional chemical resistance and thermal stability, this hydrophobic membrane is widely used in research labs, pharmaceutical testing, and environmental analysis. Whether you’re filtering aggressive solvents or preparing samples for HPLC, this PTFE filter ensures consistent performance without compromising integrity.
One of the key advantages of PTFE membranes is their inert nature, making them compatible with a broad range of chemicals, including strong acids and organic solvents. Unlike cellulose-based filters, PTFE won’t degrade or leach contaminants, ensuring pure results every time. The 6-10 micron pore size strikes a balance between flow rate and particle retention, making it versatile for both coarse and fine filtration needs.
At eqipped, we understand the importance of having reliable lab supplies that meet rigorous standards. This PTFE membrane is sourced directly from Thermo Fisher, a trusted name in scientific products, so you can be confident in its quality and consistency. Available in convenient pack sizes of 50g, 250g, and 1kg, it’s easy to stock up for high-volume applications or smaller-scale experiments.

Why PTFE Membranes Are Essential for Labs
PTFE (Polytetrafluoroethylene) membranes are a staple in laboratories due to their unique properties. Here’s why researchers and educators prefer them:
Chemical Resistance: PTFE is virtually inert, resisting attack from almost all chemicals, including hydrofluoric acid and strong bases. This makes it ideal for filtering corrosive or reactive samples.
Thermal Stability: With a melting point above 300°C, PTFE membranes can withstand autoclaving and high-temperature applications without losing structural integrity.
Hydrophobic Nature: Unlike hydrophilic membranes, PTFE repels water, making it perfect for venting applications or filtering non-aqueous solutions without clogging.
Low Protein Binding: Critical for biological samples, PTFE minimizes protein adsorption, ensuring accurate downstream analysis in proteomics or molecular biology.
Whether you’re working in a university lab, R&D facility, or quality control department, having a stock of PTFE membranes ensures you’re prepared for any filtration challenge. Buy PTFE filters online at eqipped and experience hassle-free procurement with genuine Thermo Fisher products.
Applications of 6-10 Micron PTFE Membranes
This specific pore size is particularly useful for:
Sample Clarification: Removing particulate matter from solutions before analysis, such as in environmental water testing or pharmaceutical formulations.
Air and Gas Filtration: Used in vent filters for cell culture flasks or as pre-filters in gas chromatography to trap moisture and particles.
Solvent Filtration: Ideal for filtering organic solvents in HPLC or LC-MS sample preparation, where chemical compatibility is critical.
Particulate Analysis: Collecting airborne particles or dust samples for environmental monitoring or industrial hygiene studies.
For educators, this membrane is also a great tool for demonstrating filtration principles in chemistry or biology labs, thanks to its durability and ease of use.
How to Choose the Right PTFE Membrane
Selecting the correct membrane depends on your specific application. Here’s a quick guide:
Pore Size: 6-10 micron is a mid-range option, balancing flow rate and retention. For finer particles, consider smaller pore sizes (e.g., 0.22 micron for sterilization).
Thickness: Thicker membranes offer better mechanical strength but may reduce flow rates. Thermo Fisher’s PTFE membranes are optimized for both durability and performance.
Format: Available as sheets or rolls, choose based on your lab’s needs. Sheets are convenient for small-scale use, while rolls are cost-effective for high-throughput applications.

Safety and Handling
While PTFE is chemically inert and non-toxic, proper handling ensures longevity and safety:
Storage: Keep membranes in a cool, dry place away from direct sunlight. Avoid folding or creasing to prevent damage.
Usage: Use clean tweezers or gloves to handle membranes to avoid contamination. For critical applications, pre-wet with ethanol or isopropanol if needed.
Disposal: PTFE is non-hazardous, but follow your lab’s waste disposal protocols for used filters.
Risk Note
Warning: While PTFE is stable under normal lab conditions, avoid exposure to molten alkali metals or strong fluorinating agents, as these can degrade the material. Always use in a well-ventilated area when handling fine particulate matter.
FAQs
What is the difference between PTFE and PVDF membranes?
PTFE is more chemically resistant and hydrophobic, while PVDF offers better protein binding properties and is often used in biological applications. Choose PTFE for harsh chemicals and PVDF for protein-based work.
Can PTFE membranes be autoclaved?
Yes, PTFE membranes can withstand autoclaving at 121°C, making them suitable for sterile applications. Ensure they are dry before autoclaving to prevent water absorption.
Is this PTFE membrane suitable for filtering acids?
Absolutely. PTFE is resistant to most acids, including hydrochloric, sulfuric, and nitric acid, making it ideal for aggressive chemical filtration.
How do I cut PTFE membranes without damaging them?
Use a sharp, clean razor blade or a membrane punch tool. Place the membrane on a soft, clean surface (like a cutting mat) to avoid tears.
What is the shelf life of PTFE membranes?
When stored properly in original packaging, PTFE membranes have a shelf life of 3-5 years. Avoid exposure to humidity or extreme temperatures.
