According to the given principles of Hawach, there are three general sorts of syringe filter products specially designed for different customers' requirements.
With a high class, transparent color and imported membrane, the FILTSTAR is obviously distinguished with three standards, one of which is whether the filter has pre-filtration(for the PP or GF), the other is the sterilization method, and the rest depends on membrane materials(Active Carbon/ Nylon/ PTFE/ PTFE L/ PES/PVDF/ MCE/ CA/ GF/ PP).
This one is manufactured with lower classification, colored ring and domestic membranes. However, compared with the FILSTSR, it merely possesses non-sterile products and less membrane materials(Nylon/ PTFE/ PTFE L/ PES/PVDF ).
It is high classified, designed with transparent color and the same membrane as Millipore, but PUSTAR still has less materials in the membrane as Nylon, PTFE, PTFE-L L and PVDF are recorded.
In addition, the usage range of different membranes seems to be worth mention. The table below specifically demonstrates various applications.
|Membrane Of Syringe Filter|
|Gas Filtration/Sterile Ventilation||Liquid Filtration|
|Active Solution||Hydrophobic PTFE||Hydrophobic PVDF||Aqueous Solution||Mixed Solvent||Organic Solvent|
