The All-American Pressure Sterilizers differ from the Pressure Cookers in several ways that make them better tools for the mushroom cultivator. A stopcock prevents steam from escaping once sterilization temperatures have been achieved (the Pressure Cooker utilizes a weighted vent pipe instead); this means that they require less monitoring than the Pressure Cooker. These units also feature a capillary tube and a removable solid insert basket. These units are identical in function to our electrical steam sterilizers but designed to be used on a stove top or similar heat source.

All American steam sterilizers are used world-wide to sterilize a wider range of materials. Temperature, pressure and time are the main factors in this process. All American Sterilizers make it possible for doctors, dentists, first aid stations, hospitals, laboratories and of course, mycologist to have dependable sterilization facilities in a portable unit at an extremely low cost.
Portable, Economical, Reliable Operation
Compact and portable, All American Sterilizers will quickly recoup their economical cost in the savings of time alone. There are no additional supplies to purchase, nor are there any maintenance costs other than the energy consumed. The sterilizers are made of a high-quality cast aluminum alloy that resists aging and corrosion, ensuring years of trouble-free operation.
Our Metal to Metal Seal
The metal to metal seal eliminates all rubber gaskets. As a safety feature clamping locks prevent removal of the cover while there is pressure present. An accurate pressure gauge, pressure control valve over-pressure safety plug, and cool Bakelite handles and wingnuts are all thoroughly tested features that assure safe operation with a minimum amount of attention. The portability of these sterilizers provides a complete and efficient sterilization unit at an exceptionally low cost, while meeting all clinical requirements. Only a small amount of water is needed to create the dry steam. After achieving a minimum temperature of 250° F (121° C), and a pressure of 15 PSI, the dry steam penetrates the substrate and successfully sterilizes your material.
Pressure Gauge Accuracy
The pressure gauge is rated as having an accuracy of 3%-2%-3%. This designates plus or minus 3% of the full span for the first and last quarter of the dial, and 2% for the middle 50% of the dial. More specifically, this gauge rating conforms to the pressure gauge standard ANSI B40-1-1980. This standard is entitled “Gauges-Pressure, Indication Dial Type-Elastic Element,” and covers every aspect of pressure gauge manufacture and use. The gauge is considered “Accuracy Grade B” in accordance with this specification.
Pressure Relief Valve
All American sterilizer are equipped with a new type of excess pressure relief valve. It is designed for longer, maintence-free service. The valve is designed to release pressure at 26 psi (+/- 1 psi). Each valve is equipped with a deflector cap which will direct any steam release in a downward direction.
