Sterilizer shine isn’t just about appearance…it’s also about being corrosion-resistant.

Why does shine matter on a PRIMUS steam sterilizer?

PRIMUS by Spire Integrated Solutions polishes every sterilizer to a mirror-like finish. You can determine the corrosion resistance of an autoclave by how shiny and smooth the unit is.

Spire is the only steam sterilizer manufacturer that polishes its steel to this corrosion-resistant standard.

A highly polished autoclave surface enhances corrosion resistance due to a few reasons:

  • Reduced Surface Area: Polishing smooths out microscopic peaks and valleys on the metal surface, reducing the overall surface area exposed to corrosive agents. This limits the potential sites for corrosion to initiate.
  • Barrier Formation: Polishing helps to form a passive oxide layer on the surface of the metal. This layer acts as a barrier, preventing corrosive agents from directly contacting the underlying metal and reducing the rate of corrosion.
  • Easy Cleaning: A highly polished surface is easier to clean and maintain. This prevents the buildup of contaminants that could trap moisture or corrosive agents, promoting corrosion.
  • Reduced Stress Concentration: Polishing can also help to reduce stress concentrations on the metal surface. Stress concentrations can create weak points that are more susceptible to corrosion. By smoothing out these stress concentrations, polishing helps to make the surface more uniform and less prone to localized corrosion.

The stainless steel makes a difference, too!

It is important to note that while polishing significantly improves corrosion resistance, the specific alloy composition of the autoclave and the environment it operates in also play a crucial role in determining its overall corrosion resistance.

PRIMUS steam sterilizers, offered by Spire Integrated Solutions, feature the industry’s smoothest and most durable 316L stainless steel surface.
