13mm 0.22/0.45um Sterile Syringe Filter MCE PES Nylon PTFE PVDF Lab Funnel with Filter 100PCS (Size : Nylon13mm 0.22um)

13mm 0.22/0.45um Sterile Syringe Filter MCE PES NYLON PTFE PVDF Lab Funnel with FilterSterilization needle filter is a fast, convenient, and reliable small-volume sample filtration device that is routinely used in laboratories. It is mainly used for pre-filtration of samples and sterilization and filtration of laboratory biological fluids, culture media and media additives. The filter diameter is 13mm, 25mm, 33mm, and the processing capacity is from 0.5mL to 200mL.Packing :100PCS/boxes1. Mixed cellulose ester MCEFeatures:relatively uniform pore size, high porosity, no media shedding, thin texture,low resistance, fast flow rate, low cost of use, but it is not resistant to organic solutions and strong acid and alkali solutions, and is used for aqueous solution filtration.2. Acetate CAFeatures:Acetate cellulose membrane is an ideal choice for biological and clinical analysis, sterility testing and scintillation measurement, and its protein adsorption is low. Acetate cellulose membranehas improved solvent resistance, especially to low molecular weight alcohols, while enhancing thermal stability. Due to its high physical strength, this membrane can withstand 180 degrees of high temperature, so it is suitable for hot gases and various methods. Sterilize, while maintaining the integrity of the membrane.3. Polyethersulfone (PES)Features:It is a hydrophilic filter membrane with high flow rate, low dissolution, and good strength. It does not adsorb proteins and extracts, and does not pollute the sample. It is designed for biochemical, inspection, pharmaceutical and sterilization filtration devices. .4. Polytetrafluoroethylene (PTFE)Features:Wide chemical compatibility, can withstand strong solvents such as DMSO, THF, DMF, dichloromethane, and chloroform. It is used for the filtration of most organic solutions, especially the filtration of strong solvents that other membranes cannot tolerate. After the hydrophili
