Frequently Asked Questions

Sterlitech nylon membrane filters are made from nylon 66 (PA66) polymer, which is inherently hydrophilic, non-toxic, and resistant to many organic solvents. These nylon 66 membrane filters also include an integral nonwoven polyester (PET) support layer for added strength and dimensional stability. When evaluating chemical compatibility and filtration performance, both the nylon 66 membrane and the PET support layer should be considered.

Nylon membrane filters offer high protein binding, making them suitable for applications that benefit from strong biomolecule retention. They also provide excellent solvent resistance and broad chemical compatibility, supporting filtration of aqueous solutions and many organic solvents. In addition, nylon membranes deliver strong dimensional stability and durability, often reinforced by an inert polyester support layer, which improves handling and helps the membrane maintain its structure during filtration.
