The Yamato SM-211 is the 220V version of Yamato's SM200-class automatic high-pressure steam sterilizer with a drying stage, running a microprocessor-controlled STERILIZE or STERILIZE & DRY cycle in a 22 L (0.8 cu ft) chamber. Sterilization runs 105–123 °C at up to 0.18 MPa (26.1 psi), followed by a hot-air dry to 150–180 °C. The 115V sibling is the SM-201.

Application Profile
Steam sterilization relies on saturated steam under pressure, which transfers heat far more effectively than dry air and reliably kills spores at achievable temperatures. The SM-211 automates the full cycle: it purges air, pressurizes to the setpoint, holds the sterilization time, then cools, with an optional drying stage so wrapped goods, media bottles, and instruments come out sterile and dry.
The 22 L top-loading chamber handles routine benchtop loads (media, glassware, waste bags, instruments) in clinics, teaching labs, and research groups on 220V supply. Always run with the basket in place, fill with distilled water (1900–2000 mL) to avoid scale and corrosion, and confirm results with a chemical indicator. The self-diagnostic controller and low-water sensor prevent dry-firing, and the safety valve relieves overpressure. Never load flammable or explosive materials.
Frequently Asked Questions
What temperature and pressure does it reach? Sterilization runs 105–123 °C at up to 0.18 MPa (26.1 psi); the drying stage reaches 150–180 °C.
How large is the chamber? 22 L (0.8 cu ft): 24 cm diameter × 44.5 cm deep, top-loading.
Which voltage is this, and what should I confirm? This is the 220V variant. The SM200/300/310/510 manual itemizes the 22 L SM200 at AC115V; confirm the exact 220V current draw and heater ratings at quote. The 115V sibling is SM-201.
What water should I use, and how much? Distilled water, 1900–2000 mL, to prevent deposits and corrosion; a low-water sensor stops operation if the level is too low.
Does it dry loads? Yes. A STERILIZE & DRY cycle uses a separate dryer heater to remove residual moisture.
Do I need a basket? Yes; the manual requires the basket for every run.
Ordering & Configuration
Confirm at quote: 220V supply and current draw, chamber size versus your typical load, and siting (ventilation and clearance for the lid and steam exhaust).
Warranty: Per Yamato standard capital-equipment terms. Confirm coverage at quote.
Add to a quote to lock voltage and lead time; the SM-211 ships with a water bottle, two baskets, a bottom plate, a steam receiver (saucer), the manual, and the warranty card.
