Technically it can work. What sort of autoclave do you have? The problem with using steam (autoclave) is that the injection assembly with chip loaded has a lot of voids and dead air space, and unless your autoclave has a pressure cycler designed to get steam into these dead spaces, the sterilization won’t be all that effective. Also the plastic of the injection assembly is not well suited for long term exposure to high temps… so if your autoclave has a plastics setting, with auto-cycler, then sure I would say that’s a decent plan.
