Tuttnauer T-Top 10 vs Midmark M11

When it comes to sterilizing equipment and instruments used in various healthcare settings, different practices have different needs and requirements. When it comes to selecting the right autoclave, finding the one that meets your specific practice’s needs can be a daunting task. Given the plethora of options available in the market. Which is where we come in, to help you hopefully make a well-informed choice.

We aim to make this process a little easier for you in this blog, by comparing two autoclaves and highlighting their features and capabilities. We’ll be comparing the Tuttnauer T-Top 10 to the Midmark M11 autoclave. We’ll show you some of the specs to give you an idea of the difference in size and basic functionality.

What We’ll Cover

Chamber Size – Pretty simple rule: the larger the chamber the more you can clean in one cycle.

Volume – And the more water they hold the more cycles they can run without any added work.

Warranty – Very important because its “How long will they still repair it for me” and also ” How much do they believe in their autoclave.” 

…and More – Display, Design, Ease of Use and many other design features.


Class S can sterilize things like single-packed, multi-layer and even more massive tools. Which cannot be done by a Class N unit. Class S does have pre/post vacuum cycles like Class B. But Class S has one less vacuum pump than Class B. Meaning there’s only a single-stage pre-vac system that is less effective than a Class B.

But not all Class S units have this pre/post vac capability. The Tuttnauer T-Top 10 does have pre/post vacuum cycles when sterilizing. However, the Midmark M11 does NOT have a vacuum or air pump for drying. Meaning that while they’re both Class S, they’re very different in functionality.

Open and Closed Door Drying

In this section, we’ll look at the aspects of both Open Door and Closed Door drying.

Closed Door Drying is as the name implies. The dry cycle is activated right after sterilization without the need to open the door. The dry cycle is important, and Closed Door Drying not only tackles the sterilization and drying in one step, but it ensures that your instruments are dry right when you open that door, and remain sterile until they’re needed. Closed Door Drying utilizes filtration of air to the chamber to ensure all air used for the drying process is completely sterile.

Open Door Drying is different from closed door drying. As the drying cycle doesn’t activate right after sterilization. Open Door Drying is the process of manually enacting the drying process by opening the door after sterilization. By opening the door, the ambient air outside the unit is let into the chamber. All while heat from the autoclave is also being supplied to dry the load in the chamber. But this means that the air outside the chamber that’s let in is NOT sterile, unlike the air when Closed Door Drying.
