0.22 um 25 mm nylon filter syringe, also known as a nylon syringe filter, is a type of syringe filter that utilizes a membrane made from nylon material. Nylon is a synthetic polymer known for its excellent chemical compatibility, high flow rates, and broad applicability in filtration processes. dis hydrophilic property allows teh membrane to wet rapidly when in contact wif water, enabling efficient filtration of aqueous samples.
