0.22 µm PES Syringe Filters (Pack of 50)

What it is: These 0.22 µm PES (Polyethersulfone) syringe filters are gamma-irradiated sterile filtration units featuring a 25 mm diameter hydrophilic membrane engineered for analytical sample clarification and cold sterilization of peptide reconstitutions.

How it works: The polyethersulfone membrane provides exceptionally low protein-binding characteristics (<0.1% peptide loss), ensuring that delicate peptide sequences pass through quantitatively while bacteria, particulates, and micro-contaminants are reliably captured.

Why researchers study it: Essential laboratory hardware for sterilizing sensitive peptide solutions that cannot undergo thermal autoclave sterilization.
