The Steelco US 80 model has been designed as a practical and high reprocessing capacity device for the pre treatment of complex micro surgical instruments. The effective cleaning action of Steelco Active Flushing Technology is due to the combined decrusting action of the utrasonic effect and a powerful channel flushing. 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.
