200L Commercial Pressure Sterilizer – Digital Electric Mushroom Autoclave

One of the newest additions to our Professional Series, the 200L (212 Quart) Vertical Autoclave is a true commercial-grade unit—offering massive capacity while taking up just 29" x 29" x 51" of space! This is the sterilization equipment used by top mushroom farms and labs across the country.

Manufactured by a company known for producing industrial workhorse autoclaves for over 15 years, this unit is a standard-setter for value, safety, and quality. It features full digital control of cook cycles, temperature, pressure, and timing, making it a true “set it and forget it” machine.

Extremely easy to set up and operate—just dial in your desired sterilization parameters (PSI, temperature, and time), press start, and the machine takes care of the rest.

5 Star Tech Support!

I bought one about 19 months ago, out of the warranty period, was moving locations and something must have come loose inside during the move. I called Midwest and spoke with Brian and Jay about 3 times last week and they were so helpful. Brian walked me through on a Facetime call and he noticed a wire was hanging where it wasnt supposed to be. I plugged it back in and it was running like new again, just want to let you guys know how much time you saved me and anyone on the fence about buying any autoclave from these guys should pull the trigger, the tech support alone is worth it. I can't say enough about their team but want to share this experience. Peace and love guys! - Ray

Great Machine

Very easy to operate with plenty of room for my bags. Actually this machine can fit a little more than I expected! Run times are a little longer to get to pressure when I max it out but it sterilized like it should and am seeing zero contam in my bags! I have it hooked up to a 40AMP breaker in my garage and even though it draws 36AMPS, that breaker works fine!

SPACE FOR EVERYTHING!

Running one for 3 weeks and LOVE this unit. Plenty of space, extra control over venting, can pasteurize or sterilize and the lid is just so easy to open and shut. (Step stool not included, you'll thank me later)

200L

I Was debating between the 150 and 200L for a month and while the 150L is really good value, the extra space and future proofing my farm was the ultimate decision maker for me. I've used this for a few weeks now and with any machine it took some runs to get my bag placement optimization right. I have seen a 150L and the inner metal tubs are much thicker than these. These include wire baskets that you stack on the bags and not themselves. They work fine, but I was trying to line them up to stack and that's obviously not how they were designed. Let me say this, this baby can fit almost 2 more rows of bags than what the math says based on the specs. I have noticed the heat up or get to temp time is about 90 minutes when I overload it but the overall cycle time only is extended about 45 minutes and I get an extra 10-12 bags. I've had zero issues with contams as well. If your budget falls in this price range, I highly recommend. Also, great customer service and very knowledgeable autoclave tech support staff.

PS. Fits through a standard doorway! Wohoo!
