Build a more reliable sterile workflow with the All American 75X-120V Electric Sterilizer Pressure Cooker. Designed for serious mushroom cultivation, this high-capacity pressure sterilizer helps prepare substrates, culture media, and other heat-safe supplies with consistent, repeatable results.

Unlike standard pressure cookers, the All American 75X features a stopcock that helps prevent steam from escaping once the desired pressure is reached. This supports stable operating conditions and efficient sterilization—an important advantage when preparing materials for clean culture work.

The integrated 120-volt electric heating system provides a practical setup for indoor cultivation spaces, laboratories, and production areas without requiring a separate stovetop burner. Its substantial capacity is well suited to growers processing multiple vessels or larger batches at a time.

Built for demanding use, the pressure sterilizer offers the durable construction and straightforward operation expected from All American equipment. It is a dependable choice for hobbyists scaling up, educators demonstrating sterile technique, and commercial growers refining their workflow.

Use appropriate pressure-rated containers and follow the manufacturer’s operating, loading, and maintenance instructions. Allow sufficient cooling time before opening, and always verify that pressure has fully released.

For indoor mushroom cultivation, the All American 75X-120V Electric Sterilizer Pressure Cooker provides the capacity and control needed to support consistent preparation from batch to batch.

How it works

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 17psi, the dry steam penetrates the contents, making them sterile in 35 minutes and ready for immediate use. No wiping is necessary to remove chemical residue or moisture, and cutting edges are not dulled.

Just a small amount of water is needed to create the dry steam for this sterilizer. After achieving a minimum temperature of 250°F(121°C), and a pressure of 17psi, the dry steam penetrates the contents, making them sterile in 35 minutes and ready for immediate use. No wiping down is necessary to remove chemical residue or moisture, and cutting edges are not dulled.

  • Always remember to operate your All American Sterilizer with (preferably distilled) water. Be sure to check the manual and adjust parameters for high altitudes.
  • Jars, bottles, slants, etc. must be loosely capped so the steam can vent. Tools can be sterilized wrapped in foil.
  • Start with the control valve open. While the unit heats up, allow steam to be released from the valve for 5 minutes, then close the valve. Pressure will start to build and when the pressure gauge reaches the green zone (17-18 psi), open the control valve again and let it vent for 3-5 minutes.
  • When pressure returns to the green zone (17-18 psi), start timing the cycle for 35 minutes. When the cycle is done, shut off the unit and vent from the control release valve again but do not open the lid until pressure gauge reads 0 psi.

Cautions & considerations

⚠ BURN WARNING:

IMPROPER USE MAY RESULT IN SCALDING INJURY

Sterilizer operates under pressure. Read and understand operating instructions before use to prevent accidental injury.

  • Unit must be properly closed before operating to prevent possible injury.
  • Unit will become hot during use. Do not touch hot surfaces.
  • Always use caution when handling unit when it is hot.
  • Always closely supervise children and pets when sterilizer is in use.
  • Extreme caution must be used when moving the sterilizer containing hot liquids.
  • Do not use the sterilizer for other than its intended use.
  • Always check the pressure release devices for clogs before using your sterilizer.

⚠ WARNING:

POLYPROPYLENE MELTS ABOVE 25PSI AND 350°F

Plastic grow bags are designed to withstand high temperatures during sterilization. However prolonged direct contact with the base of an autoclave or pressure cooker can result in damage to bags.

  • Never leave bags unattended in an autoclave or pressure cooker. 
  • Keep bags away from the metal sides of your equipment to avoid damage. 
  • Any sudden change in pressure will cause bags to rupture or burst. 
  • Always allow autoclave or pressure cooker to cool down and depressurize before opening to remove bags.

Additional cautions & considerations:

  • Before each use make sure that your gauge reads zero.
  • NEVER loosen wing nuts until the steam pressure gauge reaches zero and have allowed remaining pressure to escape by opening the control valve in the vertical “open” position.
  • NEVER open the sterilizer until the unit has cooled and the internal pressure reads zero on the steam pressure gauge.
  • NEVER use this sterilizer for cooking or processing food.
  • NEVER run the unit without water. Doing so will damage the heating element.
  • NEVER move your sterilizer while it is pressurized.
  • Be sure to keep metal-to-metal seal lubricated.
  • To prevent lime and mineral buildup, use distilled or deionized water in sterilizer.
  • Do not subject your sterilizer to sudden extreme temperature changes, as this may cause expansion or contraction of the metal which can damage any aluminum device. Do not move sterilizer from a cold storage area directly onto a hot flame or element. Do not add cold water to a sterilizer which has been boiled dry and remains hot. Do not cool sterilizer by pouring cold water into or on the unit.
  • As in all clinical/laboratory settings, wear safety glasses when attending to your sterilizer.
