Description of Water Prefiltration
WECHENFIB PES-Syringe Sterilization Filter have good hydrophilicity, low protein adsorption, high chemical and thermal stability, strong acid and alkali resistance (pH 1-13) solution stability, high mechanical strength and low dissolution rate. It can be sterilized by autoclaving (30min/121℃) and ethylene oxide, etc. It is suitable for water-based solution filtration and biological sample preparation.

The filter capsule is made of polyether sulfone (PES), a material known for its high temperature resistance, chemical corrosion resistance, high mechanical strength, and excellent biocompatibility. Typically designed for single-use, it features a compact structure that facilitates connection to syringes. It is suitable for various applications requiring preliminary filtration of water samples or liquid samples.
1.HPLC, MS sample preparation
2.Water-based solution filtration
3.Tissue medium filtration
4.Microbial media filtration
5.Buffer solution filtration
6.Pharmaceutical solution filtration
* Biocompatibility: The filter capsule will not contaminate the liquid medicine or liquid samples in water, ensuring the safety of the filtration process;
* It includes a filter membrane with a fine pore size, which effectively retains particulate matter while allowing the liquid to pass through;
* It is used for preliminary water filtration to prevent particulate matter from entering subsequent precision filtration or analytical equipment;
* 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;
