Selection and Precautions Before Using the Syringe Filter

In the use of syringe filters, it is often important to ensure the integrity of the filters. The significance lies in:
1. Confirm the actual filter aperture of the membrane;
2. Check whether the filter package is intact;
3. Detect damages;
4. Confirm correct installation;
5. Confirm that the filtering system achieves the verification performance.
Ultrasonic welding and secondary plastic sealing are generally adopted for syringe filters. The production environment reaches 100,000 grade purification workshop. Check UV dissolution detection and IC ion monitoring. Use medical-grade all-electric injection molding machine and medical-grade ultrasonic welding machine.
Syringe filters play an important role in HPLC analysis and ion chromatography. Save time and effectively filter impurities.
Regarding membranes selection, we need to consider the characteristics of the sample to be filtered, such as a hydrophilic sample, organic compound sample, inorganic compound sample, protein solution sample, strong acid, and strong base sample.
Type of syringe filters
1. Water system (cellulose);
2. Organic system (polyvinylidene fluoride);
3. Nylon;
4. Polyteflon;
5. Polyether phenol.
Without honesty, there will be no future for enterprises. Hawach’s syringe filters strictly control quality.
