For Q500 / Q700 Sonicators A Cup Horn offers indirect sonication and functions as a high intensity ultrasonic water bath. Multiple samples can be processed in sealed tubes eliminating cross contamination or aerosol issues. The horn is mounted within an acrylic cup and the cup is filled with water. Sample tubes are placed in a rack at a fixed distance above the ultrasonic horn. Cavitation is produced in the water, processing the samples within the tubes. Both #440 and #451 tube racks are included. #440 is made for 1.5ml polystyrene tubes which are proven to process samples more efficiently than 1.5ml polypropylene tubes. #451 is used with standard polypropylene tubes. Sonication generates heat so inlets for cooling are located on each side of the cup. The #4905 Chiller is recommended for maintaining both the water temperature and water level within the Cup Horn. Maintaining a fixed water level is extremely important and only the Qsonica chiller can accurately control this variable. The Sound Enclosure is highly recommended for all Cup Horn users. In addition to reducing sonication noise to safe levels, it securely holds the Cup Horn in place. The Sound Enclosure features ports on either side to allow coolant tubing to pass from the Cup Horn to the Chiller. Part # 431C2 Inner Diameter of Cup: 5.5" Diameter of Horn: 2.5" Tube Racks #440 and #451 are included.
For Q500 / Q700 Sonicators The Cup Horn for the Q500 and Q700 (431C2) includes tube holders 440 and 451. In addition to the standard holders, Qsonica offers custom sample tube racks to meet your specific process requirements. Please, contact a Qsonica representative for more information.

Standard Probes For Q500 / Q700 Sonicators Horns (also known as probes) are made from titanium and machined to specific sizes and shapes. When driven at their resonant frequency, they expand and contract longitudinally. This mechanical vibration is amplified and transmitted down the length of the probe. In liquid, the probe causes cavitation which constitutes the main mechanism for sample processing. Choosing the appropriate horn is extremely important. The sample volume to be processed is directly related to the tip diameter. Smaller tip diameters (Microtip probes) deliver high intensity sonication, but the energy is focused within a small, concentrated area. Larger tip diameters can process larger volumes, but offer lower intensity. Probes are offered with replaceable or solid tips. Probe tips will pit or erode over time and require replacement. Using an excessively worn tip can affect your results and possibly overload the generator. Solid probes must be used for samples containing organic solvents or low surface tension liquids.

The 15ml and 50ml tube holders are made to accommodate conical screw cap tubes. In addition to these tube holders, Qsonica can design and manufacture custom sample tube racks to meet your specific process requirements. Please contact a Qsonica representative for more information. Photos show 431C2 cup horn with tube holder. Cup horn accessory is sold separately. Use of polystyrene or similar tube material is recommended. Polypropylene or soft plastics do not work as efficiently and will result in poor sample processing.
