Performance & Design
These high-performance 0.22 μm PES syringe filters are engineered for laboratory analysis and sample preparation where accuracy, repeatability, and reliability are essential. The hydrophilic PES membrane supports fast flow rates and low protein binding while effectively removing particulates and microorganisms. Advanced welding technology ensures a solid, leak-resistant housing structure, minimizing bypass risk and maintaining consistent filtration integrity during use. The compact 4mm format reduces hold-up volume and product loss, making it ideal for small-volume filtration applications.
Packaging
Each filter is sterile and individually wrapped to preserve cleanliness and convenience, making them ready for immediate use.

Always timely and straightforward. Fast shipping. Quality products for your research lab.
There’s a one star review mentioning the filter states “not for medical use.” Well, why would anyone use a needle filter for medical use (as in on a patient or directly into a patient)? Needle filters are for lab use. That is what these are. Some people are special experts in their own minds.

filters are ‘sterile’ but say ‘not for medical use’
Michael Osterhoudt –
This is just what I needed. Work as expected.
