Sample Preparation

Syringe filter order guideline Choosing the right membrane is important. The wrong membrane could cause loss of valuable samples, time and money. Please use below guideline and chemical compatibility table as reference.     Hydrophilic Nylon   pH 6-13 Naturally hydrophilic, high protein binding, high dirt-loading, surfactant-free and offer the lowest extractables. Filtering of general samples and organic solvents. Not recommended for use with acids. Hydrophilic PVDF (polyvinylidene fluoride)   pH 3-12 Extremely low protein binding. Good chemical compatibility. For filtration of non-aggressive aqueous and mild organic solutions, or when maximizing protein recovery is important.   Hydrophilic RC (regenerated cellulose)   pH 3-12 Hydrophilic membrane with good solvent resistance. Low protein binding and extractables. Good chemical compatibility with nearly all common HPLC solvents and stable against DMSO. Good for general filtration, tissue culture media filtration or life science applications. Hydrophilic PES (polyethersulfone) pH 3-12 Low protein binding and extractables. Good for life science applications.   PTFE   pH 1-14 High chemical compatibility. High temperature resistance. Good for filtration of gases, aggressive chemicals, and strong acid.   Cellulose Acetate (CA)   pH 4-8 Low protein binding For filtration of aqueous solutions Good for applications involving culture media Mixed Cellulose Ester (MCE) pH 4-8 High protein binding Good for general filtration of aqueous solutions.
