Munktell Polyamide membrane filters:

Polyamide membranes are both hydrophilic and chemically resistant to most bases which makes them excellently suited as particle remover or sterilization filter for alcaline solutions.

Good compatibility with many solutions and aqueous samples makes them an economical choice for the clarification of the mobile phases for HPLC.

The high adsorption capacity and good mechanical strength make them useful for blotting techniques such as transfer and immobilization for nucleic acids.

They are not recommended as sterile filters for tissue culture solutions. Cellulose acetate membrane filters should be used for this application.
