Some Aspect Introduction of Syringe Filter

HAWACH specializes in various lab consumables and its syringe filter is one of the best sellers. The filter housing material is made of sanitary polypropylene material. It features of precise structure design which ensures smooth filtration, rationalization of internal space, very low residual rate, which is less than half of other products on the market, thus reducing the waste of samples, user-friendly design, ability to withstand higher burst pressure, stable membrane quality and zero difference between batches and so on.

Low Adsorption of Syringe Filter

The lab Luer lock syringe filter adopts an imported high quality microporous filter membrane, which has little adsorption to the sample and ensures the large recovery of a small number or high value sample. In practice, it provides with low dissolution, good chemical compatibility, high density polyethylene material, and so on. Moreover, it adopts ultrasonic welding, which causes no colloid or sealant, and does not pollute the sample. Hawach syringe filter is available in mixed cellulose membrane, nylon membrane, and polyvinylidene fluoride membrane. It is provided to meet the different requirements of the user for the quantity and chemical compatibility of the filtered samples.

Good Chemical Compatibility of Syringe Filter

The organic Luer lock syringe filter adopts nylon microporous filter membrane, which provides with good chemical compatibility and excellent chemical solubility for methanol, acetonitrile, n-hexane and general organic solutions. The shell is made into different colors, and it can be used to filter organic solvent samples or aqueous solvent samples. A mixed cellulose microporous membrane was used in water, which is used to filter water solution samples, and is not suitable for filtering organic solvent samples. Syringe filters can quickly and effectively filter both aqueous and organic solutions.

Corrosion and Pressure Resistance of Syringe filter

Hawach lab Luer lock syringe filter is widely used in the laboratory, because it does not need to change the membrane and clean the filter, and then saves the complicated and time-consuming preparation work. It is mainly used for sample pre-filtration, clear removal of particles, liquid and gas sterilization filtration. It is the preferred method for filtering HPLC、GC small samples.

Syringe filter shell material is polycarbonate plastic, the upper and lower part is ultrasonically welded into one, which has high pressure resistance, and there is no product leakage problem. Hydrophilic PTFE syringe filter contains hydrophobic PTFE membrane and is an effective filter for solvents, chemicals and other non-aqueous solutions. Teflon film and strong polypropylene shell are especially suitable for filtration of corrosive chemicals.

Smaller Dead Volume of Syringe filter

Surface filter membrane and high-quality shell materials to ensure the stability and safety of raw materials, with a larger filter membrane area and smaller dead volume, effectively increase the flow rate and filtration volume and improve the filtration efficiency. Advanced reinforced secondary injection molding process can withstand higher operating pressure, improve filtration speed, and make filtration easier and easier. And excellent economy makes it achieve ambassadorial effect at low cost.
