The reason why 5 micron syringe filter is widely used in experiments is that it is time saving, no need for membrane replacement and filter cleaning, without complicated and time-consuming preparations.
HEPA syringe filter main uses include liquid/air sterilization filtration, sample prefiltration, clarification, and removal of particles. The syringe filter is composed of polycarbonate plastic housing, with its upper and lower parts welded together by ultrasonic, featuring high pressure resistance and good sealing.
We can see the uses of syringe filters in many applications, such as food, medical, municipal water treatment, wastewater treatment and reuse, and material concentration and purification. Also, it can be used in dairy product manufacturing, semiconductor manufacturing, food manufacturing, paper manufacturing, and pharmaceutical manufacturing, etc. For this, operators will choose the ultrafiltration membranes and microfiltration membranes.
The use of a syringe filter is a cheap and effective method to improve the quality of HPLC analysis, make the analysis results stable and continuous, and have a long service life of the chromatographic column. Before entering the chromatographic column, by removing impurities in the sample, the HAWACH syringe filter makes the liquid flow unimpeded in the chromatographic column. Without the obstacles of these impurities, your column will work more efficiently and lastingly. The unique design makes the filter has a larger membrane area and a smaller dead volume.
HAWACH provides various filter membranes for syringe filters to meet different experimental and test requirements, such as active carbon, nylon, PTFE, PES, PVDF, CA, GF, PP, and MCE. For instance, the mce syringe filter has pore sizes of 0.22, 0.45, 0.8um, and its diameter has 13, 25, 30 with sterile and non-sterile packaging. From the appearance, HAWACH syringe filters are beautiful and compact, with easy operation, precise and reliable performance, high cleanliness, a variety of specifications, and packaging.
HAWACH has summarized several aspects to consider when choosing a syringe filter.
It is hoped the syringe filter can remove as much bacteria as possible without introducing other substances, such as bacterial endotoxins or chemical precipitates, as it is sterilization.
2. Filter membrane.
Many kinds of filter membranes used in syringe filters are available, like we’ve mentioned above. Both chemical compatibility and filtration time should be considered when purchasing.
After determining the filter membrane, it is relatively easy to select specifications.
