The "PES syringe filter capsule" refers to a filter capsule for syringes made of polyether sulfone (Polyether sulfone, abbreviated as PES) material; it has good chemical stability, heat resistance and mechanical strength. The PES syringe filter capsule can effectively remove bacteria, particles and other impurities in the medicinal liquid while filtering it, ensuring the safety and effectiveness of injectable drugs.

2.Tissue medium filtration
3.Microbial media filtration
4.Buffer solution filtration
5.Pharmaceutical solution filtration
* The inside of the filter capsule adopts a multi-layer structure design, including a filtration layer, a support layer, and a shell. The filtration layer is composed of PES microporous membrane, which can effectively intercept impurities such as bacteria and particles; the support layer provides additional strength to ensure that the filter capsule is not easily damaged during the filtration process;
* It has excellent filtration performance and can achieve efficient filtration;
* It has good chemical resistance and is suitable for filtering a variety of medicinal liquids;
* Bi-directional filtration;
* 100% passed integrity test;
* Ethylene oxide;
* Strict quality control system, complete production process flow;
* Short delivery period;
* Flexible payment method: T/T, L/C, West Union, Paypal;
* Free technical support;
* Other specific sizes can be customized;
