Syringe filter could be divided into a disposable and multiple-time filtering tool based on its usage frequency. In terms of the different filter membranes used, there are five kinds of syringe filters mainly used for the lab experiments, including Nylon, PVDF, PTFE, CA, Glass Fiber, PP, PES syringe filter. Especially, the PVDF, PTFE, Nylon and PES filter would be specifically introduced as below.
Hawach syringe filter is a cost-effective way to improve the quality of HPLC analysis, and suitable for a multiple of other applications. Precisely designed structure ensures the fluency of the filtration, improves consistency, extends column life and reduces maintenance. By removing particles before the sample enters the column, Hawach syringe filter allows unimpeded flow.
Besides, reasonable inner space minimizes the hole-up volume, so that the waste is greatly reduced. Housing material is medical grade polypropylene, which gives it better chemical compatibility and excellent chemical stability. Edge is matched with screws which makes operator more convenient to use. Standard female and male lure lock provides better sealing effect and greater strength to the filter housing without leakage and bursting.
Hawach Scientific is noted for the most advanced equipment, the strict testing process, and the best service. Hawach research team keeps on investing and testing syringe filters for lab industry and pursuing perfection, and makes endeavor to offer the best syringe filter to customers.
Avoid the introduction of other impurities in the filtration process, especially the shell materials or shed particles from the filter membrane, if it is used to treat chromatographic samples. Different types of syringe filters are suitable for different properties of samples due to different materials.
As a matter of fact, there are hydrophobic and hydrophilic PVDF syringe filter. The most significant feature of the PVDF membrane is its low protein adsorption. Also, the high flow rate improves the filtration speed, especially for the biological samples. It is resistant to a high-temperature environment, most chemically corrosive samples, and oxides.
Just like the PVDF filter, there are also both hydrophilic and hydrophobic membranes for the PTFE syringe filter available to meet different liquid filtration needs. Its excellent chemical resistance gives itself a great marketing prospect. To be more specific, it is highly resistant to high temperature, strong acid, and alkali solutions and solvents.
Nylon Syringe Filter
The Nylon syringe is highly qualified for the filtration of strong alkali and organic solvents with superior mechanical strength. Due to its natural hydrophilicity, there is no need to infiltrate the membrane before use.
PES Syringe Filter
The PES syringe filter is quite suitable for the high-throughput and high-efficiency filtration. Its protein adsorption and dissolution are quite low, which equips it with high microbial filtration capacity.
