Stopper Bowl Covers provide a convenient, time-saving method of wrapping stopper bowls prior to sterilization. These covers promote excellent steam penetration and drying during sterilization. In addition, each cover can remain in place on the bowl during setup, which minimizes the possibility of contamination. Made from Tyvek®, they are puncture resistant and extremely tough. STERIS Barrier Product Solutions stopper bowl covers incorporate latex-free rubber elastic or Tyvek drawstrings to create a positive seal.
