GST syringe filter automatic production line equipment manufacturers believe that the small partners who do experiments have used disposable syringe filters. Any type of sample (food, soil, water sample, etc.) must be used once after pretreatment and before the sample is put on the machine. Filtered with a syringe filter to remove impurities and particles from the sample solution, so as not to block the instrument for long-term accumulation.
The shell of the needle filter is made of polycarbonate, polypropylene and polyethylene plastics. The upper and lower parts are welded together by ultrasonic waves. It is resistant to high pressure and there is no problem of product leakage.
The needle filter is widely used in the laboratory. It does not need to change the membrane and clean the filter, which saves the complicated and time-consuming preparation work. It is mainly used for sample pre-filtration, clarification and particle removal, and sterilization filtration of liquids and gases. It is the preferred method for filtering small samples by HPLC and GC.
