Stainless Steel Autoclave Machine with High Pressure and Temperature Sterilization

AISI 304 stainlss steel at 3mm wall thickness is what you're getting here, and that matters because of that it handles the repeated thermal cycling from 134°C working temperature without developing stress cracks over hundreds of cycles.

Working pressure sits at 0.22MPa with a max of 0.23MPa, so you've got about a 4.5% safety margin above the operating point—that's tighter than most vertical autoclaves we see, usually give or take 10%. The heat average of ≤±1°C means the thermocouple placement and PID tuning are actually decent, not just a number on a spec sheet.

You set temperature anywhere form 105 to 134°C, and the timer runs up to 99 minutes or 99 hours 59 minutes depending on which mode you pick. What it does is let you program a slow ramp for heat-sensitive media or fast cycle for instrument loads—most buyers go with the 75L model because it fits a standerd benchtop and still processes four trays of wrapped instruments.

Four chamber volumes here: 35L, 50L, 75L, and 100L, but the 35L is basically too small for anything beyond a single surgical pack or some culture media bottles. The 100L is heavier at 85kg net weight (110kg gross), so you'll want to confirm floor loading before ordering that one—we usually have stock on all models, but lead time varies depending on whether you need CE or FDA paperwork stamped.

Power draw ranges from 2.5kW on the smallest model up to 4.5kW on the 100L, and that's important because most labs don't have dedicated 220V circuits that continuous load—check your breaker panel before installation. The LCD display records and prints sterilization data (time, temperature, pressure curve), which is handy for GMP audits or just tracking cycle consistency over a month or so.

One detail you might not think to ask: the door safety lock prevents opening if there's any residual presure above 0.01MPa, so it won't let you blast steam in your face, but it also means you can't crack door to check if the load is dry—you wait until the cycle finishes and teh chamber vents fully. That's fine for most lab work, but if you're flash-sterilizing instruments between surgeries, you'd want a faster cooldown cycle or a separate prevac unit.
