Syringe filters made of parent polymer material grade pes is made, and supporting the use of syringes, filter processing device routine laboratory use quick, convenient and reliable small sample volume, Mainly used in the sample prefilter, laboratory biological fluids, culture media and media additives sterile filtration. Convenient to meet the needs of experiments; ;DNase/RNase-free, no pyrogen.How to choose the right filter?Mixed fiber membrane () a mixture of cellulose nitrate and cellulose acetate made hydrophilic, chemical compatibility, high protein adsorption. For particle analysis, particle ideas, biochemical analysis, HPLC sample preparation and solvent filtration;Nylon membrane (NYLON) chemical compatibility is good, can be used under the conditions of a PH value to 12, applied to biological products, culture medium, sterile filtering the solution; chemical compatibility, applicable to the preparation of the samples, solvent filtration, microbial research, environmental analysis, biological analysis, HPLC mobile phase filtration; Polytetrafluoroethylene (PTFE) and inert chemical stability, applicable to chemical strong organic solvents, water and gases, mostly acidic, alkaline solution and have tolerance.
