What is a syringe filter
The syringe filter is a fast, convenient, and reliable filter tool that is routinely used in laboratories. It has a beautiful appearance, light weight, and high cleanliness. It is mainly used for sample prefiltration, clarification and removal of particles, and liquid and gas sterilization filtration. It is the preferred method for filtering small samples of HPLC and GC. According to the sterilization method, it can be divided into sterilization and non-sterilization.
The syringe filter does not need to change the membrane and clean the filter, eliminating the complicated and time-consuming preparation work, and is widely used in the laboratory. The product is mainly used for sample pre-clarification, particle removal, sterilization filtration, etc. Among them, the needle filter is used in conjunction with a disposable syringe. It is a fast, convenient and reliable small-volume sample filter processing device that is routinely used in laboratories. Its filter diameter is 13mm and 30mm, and the processing capacity is from 0.5ml to 200ml.
Domestic needle filters are divided into disposable and multi-use, organic or water systems, with specifications of Φ13 or Φ25, and are used for sample filtration in liquid or gas phase analysis. Filter materials are: nylon (Nylon), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), mixed.
Why the syringe filter is favored
At present, it has a good development prospect in the market and has been widely used in the market. It has attracted consumers to buy. The syringe filter industry is a high-tech and highly integrated equipment industry used in chromatographic analysis. The filtration of the mobile phase and the sample has a good effect on protecting the chromatographic column, the infusion pump tube system and the injection valve from contamination. It is widely used in gravimetric analysis, microanalysis, colloid separation and sterility test. Throughout the development over the years, my country’s syringe filter technology is constantly being upgraded and improved, and its share in the international market is also increasing, and it is favored by consumers.
What are the reasons why syringe filters are favored?
1. The clear specification mark eliminates the trouble of confusion. The filter housing material is made of high-quality sanitary polypropylene material.
2. The product structure is precisely designed to ensure smooth filtration, rationalization of internal space, and very low residual rate, thereby reducing the waste of samples.
3. One of the disadvantages of traditional filters is that they are easy to blast. This product is specially designed to withstand the blasting pressure of up to 7bar.
4. The edge part of the filter is threaded, which plays a non-slip effect, and the humanized design makes the operator handy.
5. Stable membrane quality and zero difference between batches ensure the consistency of analysis results.
