Syringe Filters, 25mm, PES, 0.22um Pore Size. White/Red Polypropylene, AQ Brand. 50/PK.
Advanced Quality PES Syringe Filters, AQ™ brand, for Pharmaceutical Grade HPLC & Dissolution Testing. Manufactured with a unique 0.22µm PES (Polyethersulfone) Membrane in a 25mm polypropylene housing, these syringe filters are made for laboratories that require consistent, high performance results with ease of use especially during high volume work. Excellent choice when laboratories cannot afford poor chromatographic results.
These filters are used for filtration and sterilization of protein solutions, culture media and buffers. The low protein binding characteristics make these ideal for this these types of applications, particularly where the sample size is very small and recovery of protein of interest is sought. PES filters provide absolute retention, very low hold up volumes and low protein binding while offering excellent throughputs.
Validated for many regulatory requirements, they are designed, tested and QC Certified. They comply with US FDA CFR Title 21, Part 211.92 for minimum Fiber Release and with USP <788> test for particulate matter in injectables as well as USP for "Sterile Water for Injection" and therefore do not require any initial flushing or discarding of the first 200µl of filtrate saving time and avoiding investigation of failed methods. The polypropylene plastic housing material complies with the requirements of US FDA CFR Title 21 Part 177.1520 and are heat sealed to prevent leaching. These filters pass a test for oxidizable matter as per the USP.
These specially manufactured PES membranes have relatively low extractable levels which are commonly used in analytical laboratories and have a relatively high particulate loading capacity.
Color Color Coded: White w/Red Lettering for 0.22µm PES, these filters can be autoclaved for 0.5 hours at 121ºC, 0.1MPa or with ethylene oxide.
