Product Description
When precision matters in your lab, the Whatman PTFE membrane filter delivers unmatched performance. Designed for demanding applications, these filters combine hydrophobic properties with exceptional chemical resistance, making them ideal for filtering aggressive solvents, acids, and bases. Whether you’re preparing samples for HPLC, analyzing environmental contaminants, or conducting routine lab work, this filter ensures reliable results every time.
The PTFE membrane’s uniform pore structure provides consistent flow rates while maintaining high particle retention. Unlike cellulose filters, PTFE won’t absorb moisture or swell, guaranteeing stable performance even with volatile organic compounds. Researchers across India trust Whatman filters for their reproducibility and durability in critical experiments.
Available in multiple pore sizes (0.2µm, 0.5µm, 1.0µm) and diameters (25mm, 47mm), you can select the perfect configuration for your specific application. Each pack contains 100 filters, ensuring you have an ample supply for extended projects. The filters come ready to use with standard filtration apparatus, saving you valuable lab time.
For labs focused on quality control, environmental testing, or pharmaceutical research, these PTFE filters offer the perfect balance of performance and value. Their inert nature prevents sample contamination, while the robust construction withstands repeated autoclaving. When you buy PTFE membrane filters online from eqipped, you’re investing in a product that meets international quality standards.

FAQs
What’s the difference between PTFE and PVDF membrane filters?
PTFE offers superior chemical resistance and hydrophobic properties compared to PVDF. While PVDF can handle some solvents, PTFE remains stable with virtually all organic and inorganic chemicals. PTFE also has a wider temperature range, making it suitable for more demanding applications.
Can I autoclave these PTFE filters?
Yes, Whatman PTFE membrane filters can withstand standard autoclaving cycles at 121°C. Their thermal stability makes them ideal for applications requiring sterile conditions. Always follow proper autoclaving procedures to maintain filter integrity.
How do I know which pore size to choose for my application?
For bacterial removal or sterilization, 0.2µm is standard. For general particulate filtration, 0.5µm offers a good balance. If you’re pre-filtering samples with larger particles, 1.0µm works well. Consider your sample type and the smallest particles you need to capture.
Are these filters compatible with organic solvents?
Absolutely. PTFE’s chemical resistance makes these filters perfect for organic solvents like acetone, methanol, and hexane. They won’t degrade or dissolve like cellulose filters might with aggressive chemicals.
How should I store unused PTFE filters?
Store filters in their original packaging in a cool, dry place away from direct sunlight. Avoid exposure to ozone or strong oxidizing agents. Proper storage ensures the filters maintain their performance characteristics until use.
