US 300

Ultrasonic Cleaning and Thermo-Disinfection for Complex Instruments

US 300 is an ultrasonic washing and thermal disinfection device for the treatment of complex microsurgical instruments. Offering an effective and comprehensive reprocessing solution, the unit is designed to reprocess over 40 hollow instruments in a single process. Steelco’s Active Flush technology, which combines the decrusting action of ultrasonic effect with powerful flushing, achieves excellent cleaning results. The standard program’s automatic execution includes the following phases: pre-washing, ultrasound washing, and active flushing rinse and thermal disinfection. At the process completion, the instruments will be free from bio-burden inside and out, disinfected, and made safe to handle before wrapping and sterilization.

US 300 is equipped as standard with a removable washing basket, allowing loading and connecting instruments on a separate workbench. Ported instruments are directly connected through standard luer lock connectors. The connection of non-ported instruments is made by the use of injection sleeves with silicone seals.
