STERIS - Amsco 400 Small
by STERIS


AMSCO® 400 Series Small Steam Sterilizers are engineered to be fully compliant with current steam sterilization standards. The 20 x 20 sterilizer is validated to accommodate a maximum of three 25-lb sets (up to 75 lbs) per load, and the 16-inch models can sterilize two 25-lb sets (up to 50 lbs per cycle), per AAMI guidance for processing weights. They also accommodate loaner sets and larger bariatric and orthopedic devices. Also, the AMSCO 400 Series Small Steam Sterilizers prevacuum and steam-flush-pressure-pulse (SFPP) cycles have been validated, per AAMI recommendation, for porous items. Validated “immediate-use” prevacuum and gravity cycles are available, replacing “flash” terminology, and cycles can be customized and named by the user. AMSCO 400 Series software reduces steam and water usage per pound of instruments processed, and the steam-activated gasket requires no lubrication.
1ReplyTue Dec 23 2025 | Amsco 400 series On startup this 1 unit goes into depressurization, 20min. But stops around the 10 min mark. Customer says it sits there all day and they cant use it. Is that a normal part of the cycle on the 400s? Chamber is empty, I can open the door and it makes no difference. When the countdown stops, could it be a calibration issue? What is thia depressurization, is it the sterilizer or the boiler, is it a feature that can be turned off? Reply |
