What types of samples are suitable for PES membranes?
PES membranes are ideal for cell culture media, buffers, protein and enzyme solutions, vaccines, and other biological samples.

Can PES syringe filters be used for organic solvents?
PES membranes are mainly recommended for aqueous solutions. For strong organic solvents, PTFE or Nylon membranes are more suitable.

Why choose PES over other membrane materials?
PES offers high flow rate, low protein binding, low extractables, and excellent mechanical strength, making it ideal for sterile and sensitive applications.

Does PES membrane require pre-wetting?
No. PES is naturally hydrophilic and ready to use for aqueous filtration without pre-wetting.

Will PES syringe filters adsorb proteins?
PES membranes have very low protein binding, minimizing sample loss during filtration.
