The Tuttnauer benchtop laboratory autoclave can come in a front-loading design that can handle 28 to 160L of materials. The EL models use a control panel designed with its own microprocessor and a chamber that features 316L or 316Ti stainless steel around its body. An internal printer can be added if desired. Tuttnauer makes these autoclaves to perform well in today's labs while also being safe to use. The door will be adjusted to where it will not open as the chamber is pressurized. Also, the cycle will not start if the door is not closed and locked. Also, the door cannot open through a user's demand if the chamber is pressurized, thus protecting all users who have to clean items as needed.
