50mL Centrifugal Filters, Hydrophilic PVDF, 0.45μm, (50 Pcs/Pack)
SpinFlow Micro Centrifugal Filters are suitable for protein purification, sample preparation, sterile filtration, and various other applications. They are designed for standard bench top centrifuges and are available in 2 mL, 15 mL, and 50 mL formats. They typically consists of a column body, a filter membrane, and support materials. The column body acts as the outer shell and is usually made of corrosion resistant, high pressure materials to ensure that it does not chemically react with or leak liquid during filtration. The filter membrane is the core component of the filtration column, and its pore size can be selected according to the required retention of different particle sizes. The support material is used to support the membrane and prevent deformation or rupture during the filtration process
Membrane Selection Guide
Membrane Type Main Application Mixed Cellulose Ester Membrane (MCE) Suitable for filtering proteins and aqueous solutions in biological samples such as blood serum medium filtration.Polyethersulfonate Membrane (PES) Suitable for filtering cell cultureNylon Membrane (NY) Hydrophilic, high protein binding, suitable for protein-free aqueous and organic solutions, resistant to alcohol and DMSO.Hydrophobic Polytetrafluorethylene Membrane (Hydrophobic PTFE) Hydrophobic, resistant to strong acids, strong bases, and high temperature: suitable for filtering highly corrosive solution, organic solutions and gases.Hydrophilic Polytetrafluoroethylene Membrane (Hydrophilic PTFE) Used for Natural product screening, solubility, testing, total drug analysis, protein precipitation analysis, bead lysis, and solid-phase synthesis.Polyvinylidene Fluoride Membrane (PVDF) Suitable for general biolgical filtration, not suitable for filtering strongly corrosive liquids, not resistant to acetone, DMSO, THF, DMF, dichloromethane, choloformCellulose Acetate (CA) Suitable for filtering proteins and aqueous solutions in biological samples, such as serum and culture medium filtration.
