0.22 Micron Disc Filter Hydrophilic PTFE Syringe Filters Non-Sterile HPLC-Certified

PTFE disc filters is a type of syring filters consisting of built-in PTFE membranes and medical grade PP housing. Hydrophilic PTFE disc filters we offer are HPLC-certified filters that are designed to remove particles from samples prior to instrumental analysis. These disc filters offer a convenient and efficient solution for sample preparation, as they can be used without the need for pre-rinsing with a solvent for filtration of aqueous liquids. The high-quality polypropylene housing ensures a wide chemical compatibility, making it suitable for a variety of applications.

One of the outstanding features of these PTFE syringe filters is they allow for higher operating pressures compared to other types of syringe filters. Additionally, the PTFE filters have leak-proof Luer lock inlet/outlet which ensures a secure and reliable connection.

These PTFE disc filters are available in 13, 25 and 33mm diameter options and come in a range of pore sizes to suit different application needs. The available pore sizes include 0.22μm and 0.45μm, providing flexibility in selecting the appropriate size for specific applications. , Moreover, these filters have been HPLC-certified, ensuring minimal levels of UV-absorbing extractables that could interfere with the analysis results. And they are color coded, making them easily identifiable and easy to handle during sample preparation. PTFE Disc filters are suitable for various analytical applications, including sample filtration before UHPLC, HPLC, and LC-MS analyses. They can also be used for filtration of aqueous and organic solvents, providing a reliable solution for sample preparation in various fields such as pharmaceuticals, biotechnology, and environmental studies.

The PTFE membranes of the disc filters are manufactured by ourselves in our Class 100,000 cleanrooms, and the housing production and product- assembly are done in our own automatic injection-molding facilites. This makes us stand out from other manufacturers who have to purchase the membranes and shells to complete the assembly, and makes us more flexible and competitive on pricing. And we offer free sample service for available ones, contact us and you'll get desirable products at amazing price!
