“6.2 Ultrasonic preparation -- A horn-type device equipped with a titanium tip, or a device that will give appropriate performance, must be used. 6.2.1 Ultrasonic disrupter -- The disrupter must have a minimum power wattage of 300 watts, with pulsing capability. A device designed to reduce the cavitation sound is recommended. Follow the manufacturers instructions for preparing the disrupter for extraction of samples with low and medium/high concentrations. 6.2.2 Use a 3/4-inch horn for the low concentration method procedure and a 1/8-inch tapered microtip attached to a 1/2-inch horn for the medium/high concentration method procedure.
