One of the labs I supervised lacked funding to purchase an autoclave. We sterilized media broth, media agar, dilution agents, Petri dishes, flasks, bottles, and other microbiology utensils in a Mirro pressure canner. We sterilized a minimum of three batches daily, five and six days a week, year round. The Mirro canners constantly required new seals, yet the lids still frequently warped and leaked all over the stove. We replaced the Mirro canner twice in a year, let alone all of the gaskets we went through. I bought this All American pressure cooker when I saw the unique no gasket design, securing lugs, and the safety features built into this pressure cooker. My micro staff loved this pressure cooker. This All American pressure cooker never leaked, the lid fit perfectly time after time, and all of our batches came out properly sterilized. It impressed me so much after almost two years' use in a laboratory setting, that I am now buying one for my home canning. Made in USA, heavily built, well-engineered for performance and safety, and proven to me in multiple daily uses with three different users, including myself--a great pressure cooker in my experience, far better than the others we tried.
