ESBE Syringe Filters

ESBE Syringe Filters are ideal for filtering culture media and organic solvents in a wide range of applications. 

Syringe Filter Selection Guide

PVDF-Hydrophilic and excellent for HPLC and GC sample prep/clean up and
protein-based samples due to broad chemical compatibility, the nature of a
low protein binder, and low UV adsorbing extractables. It can be used for
alcohols,weak acids, proteins, peptides and other biomolecules for high
protein recovery .

Nylon-Hydrophilic and commonly used for aqueous or mixed organic sample prep
and HPLC,GC or dissolution sample analysis, such as bases, most HPLC
solvents, alcohols, aromatic hydrocarbons, and THF. Not for strong acids,
strong bases and high protein recovery. Excellent flow rates with most
sample matrices and extremely low in extractables.

PES- Hydrophilic and excellent for tissue culture, media, and buffers due to very
low protein and nucleic acid binding and excellent flow rates. The PES
membrane shows better chemical resistance than cellulose acetate. It is
widely used in clinical/toxicology, ion chromatography, ICP-MS, AAS, and
capillary electrophoresis for strong bases, alcohols, proteins, peptides.

PTFE- Hydrophobic and perfect for organic solvent-based, acidic or basic samples
and all solvents, such as aggressive solvents, strong acids and bases, alcohols,
and aromatics. Chemically resistant to all solvents and has an excellent
thermal stability to high temperature fluids. It can be used with aqueous
samples after pre-wetting with small amount of alcohol and then flushing
with water.
