&&The "InnoWave Unity 20 Sonic Irrigator" is a machine designed to thoroughly clean (remove tissue, blood, and other contaminants from) a variety of lumened surgical instruments. It uses a combination of ultrasonic cavitation and low-frequency cannulated pulse enhancement (CPE) fluid recirculation to dislodge and flush away unwanted debris from both outside and inside surfaces (hollow instruments only) of items placed in the unit. The unit is made primarily of steel and consists of a tank with a removable basket, which can process up to 16 lumened surgical instruments. The overall dimensions of this unit is 34.9 x 41.3 x 25.8 inches, with the lid closed. The maximum load weight is approximately 35 lbs of lumened surgical instruments per cycle. The ultrasonic frequencies are ensured by constant power output generators operating between 38kHz and 40kHz, depending on the load.
