Nylon Syringe Filter with PP prefilter: Aqueous or organic sample prep, HPLC, GC, or dissolution sample analysis, high retention ability: PTFE Syringe Filter with PP prefilter: Aggressive solvents, filter organic-based HPLC samples, degassing solvents, aerosol sampling, venting application, vacuum pump line protection, high retention ability
Laboratory filtration is the physical or mechanical separation of particles or components within a sample medium such as a liquid or gas by introducing a medium through which only the gas/liquid can pass. Therefore a size exclusion that will separate the starting sample into two fractions. One fraction (permeate/filtrate) will be the clarified
Syringe filters with different pore size ratings are suitable for different applications. For example, syringe filters containing 0.45 μm are typically used for HPLC sample preparation and 0.2 μm is used for UHPLC. In life science applications 0.1 and 0.2 µm pore sizes provide sterilization of buffers, culture media, and additives.
