Best Pressure Cookers for Sterilization

Pressure cookers are used globally for the sterilization of glass jars and different types of vessels as well. Pressure cookers are the easiest sterilization method in less time and leave no mess behind. The key behind using a pressure cooker for sterilization has the perfect temperature and pressure. Generally, a pressure of 7psi to 15psi is required to kill the pathogens and microbes from your vessels, and it is vital that you maintain the optimum pressure level. For that purpose, we recommend that you get yourself a pressure cooker that can hold a pressure of max 15 psi. Believe it or not, a pressure cooker works best as an autoclave on budget. As long as you have a suitable cooker, there is no need to worry about unsterilized stuff.

Prior research and study can help you find the perfect cooker to sterilize and achieve perfect results.

Below, we have short-listed the best pressure cookers for your sterilization needs. Always ensure the item you want to sterilize is strong enough to withstand pressure, and always check the instructor’s manual for your pressure pot to avoid any mishaps.
