3/4 ultrasonic titanium horn (probe) with a threaded end, that focuses the ultrasonic energy into the liquid. Fabricated from high grade titanium, these horns are autoclavable and have an o-ring groove at the nodal point that allows a tight fit in a #36 Ace-Thred without affecting sonic output. The threaded end accepts replaceable tips, microtips, or extenders. Supplied with a 1/2-20 stud for connection to the converter on a power supply.
