The quick answer is no you don't need any type of plumbing for most desktop autoclaves like the Ritter M9 or the Midmark M11 although other types of sterilizers do require plumbing.
It can depend on the type of desktop autoclave you are using and the specific requirements of the autoclave.
Some desktop autoclaves may require a direct connection to a water supply and a drain for the water used during the sterilization process. These autoclaves have a built-in water reservoir that needs to be filled manually, and the used water needs to be drained out after each cycle.
Other desktop autoclaves are designed to be more portable and don't require a direct connection to a water supply or drain. These autoclaves typically use a removable reservoir that can be filled and emptied manually.
Many desktop autoclaves have built-in water reservoirs that you can manually fill with water, but this can be time-consuming and may not be practical for frequent or large-scale use. In these cases, it is common to connect the autoclave to a water source via plumbing.
The plumbing setup will depend on the specific autoclave you are using and the water source available. Some autoclaves may come with a kit for connecting to plumbing, while others may require additional parts or modifications to be made to your plumbing system. It is recommended to consult the manufacturer's instructions and seek the advice of a professional if you are unsure how to set up plumbing for your autoclave.
It's important to review the manufacturer's instructions for the specific model you are using to determine if plumbing is necessary. If you're unsure about the requirements or installation process, it's always a good idea to consult with a licensed plumber or the manufacturer of the autoclave for guidance.
