A syringe filters, which is also called wheel filter, is kind of membrane-based device to remove the particulate impurities from small liquid samples, usually ≤ 100 ml. The scientists use the disposable hydrophilic PVDF syringe filterss are commonly in labs to achieve the fast and efficient filtration, material purification, and sometimes sterilization.
Mechanical Strength and Chemical Property of PTFE Syringe Filter
Hawach hydrophilic PVDF syringe filters is of imported film, provided with high chemical and thermal stability, fast flow rate, strong acid and alkali resistance. And it is also provides with high mechanical strength.
Syringe filter which is made of Nylon 66(Nylon 66) is characterized in the following aspects: microporous membrane has good hydrophilicity, acid and alkali resistance, antioxidants.
It is not only suitable for aqueous solution containing acid and alkali, but also for organic solvents such as alcohols, hydrocarbons, lipids, phenols, ketones and so on.
In application, it does not need to change film and clean filter, and saves complicated and time-consuming preparation work. Moreover, it is mainly used in sample pre-filtration, decontamination of particles, liquids and gases. It is a method to filter HPLC, GC small samples.
Chemical Property of Hydrophilic PVDF syringe filters
The shell is made of polypropylene (PP) material with good chemical stability and makes different colors, which is convenient for users to distinguish products of different gauge materials and avoid confusion.
Membrane of Hawach hydrophilic PVDF syringe filters adopts imported high performance filter membrane, the product quality is stable, the reproducibility is good, so it is the laboratory filtration sample ideal choice. The standard interface is convenient to connect with various syringes, and can also be directly connected to various valves.
Filtration of Hydrophilic PVDF syringe filters
Hawach hydrophilic PVDF syringe filters is suitable for strict application conditions with the following features
The large filtration area makes the treatment capacity and gas flow rate higher than other similar products. Multiple access interfaces available PTFE diaphragm and polypropylene enclosures provide excellent chemical compatibility. Thus it can be used repeatedly without risks. High temperature and high pressure sterilization make it fit for bioreactor and fermenter.
Moreover,it is characterized in low adsorption, high flow rate, high total flux, bidirectional use, 100% integrity test, less dissolution Z, scale amplification, easy to identify pore size, so it can provide various specifications of outlet connection, and causes no particle release, no polyvinyl chloride.
Sterilization Performance of Hydrophilic PVDF syringe filtersHawach hydrophilic PVDF syringe filters does not need to change film and clean filter, which saves complex and time-consuming preparation and is widely used in the laboratory. The products are mainly used in sample pre-definition, particle removal, sterilization filtration, and so on.
Hawach hydrophilic PVDF syringe filters is used with a disposable syringe, which is a quick, convenient, and reliable filter treatment device for small volume samples used in the laboratory. It is mainly used for sample filtration in chromatographic analysis, it has a good effect on protecting the chromatographic column and carrying a valve from contamination.
