Product Overview

STERIS’ Vesta-Syde® SQ st Quaternary Ammonium Disinfectant is the sterile version of the Vesta-Syde SQ family of disinfectants made specifically for use on hard non-porous surfaces. The Vesta-Syde SQ products are all made with the same quaternary ammonium formulation, but are processed and packaged differently for specific applications. At a use-dilution rate of 0.8% v/v (1:128), the Vesta-Syde SQ products kill a broad spectrum of common bacteria and fungi without harming the surface.


STERIS' Vesta-Syde st SQ Quaternary Ammonium Disinfectant is a liquid concentrate specifically formulated for disinfection of hard surfaces. The use-dilution can be applied manually or sprayed.
