PROBES FOR VC 505, VC 750, VCX 500 AND VCX 750
PROBES
Probes (sometimes referred to as horns) are one-half wavelength long tools that act as mechanical transformers to increase
the amplitude of vibration generated by the converter. They consist of two sections each having different cross-sectional
areas. When driven at its resonant frequency, the probe expands and contracts longitudinally about its center. However, no
longitudinal motion occurs at the threaded nodal point (area of no activity), allowing accessories to be connected to the
probe at that point. The greater the mass ratio between the upper section and the lower section, the greater the amplification factor, and the greater the peak-to-peak excursion at the tip of the probe. Probes with smaller tip diameters produce
greater intensity of cavitation, but the energy released is restricted to a narrower, more concentrated field. Conversely,
probes with larger tip diameters produce less intensity, but the energy is released over a greater area. The larger the tip
diameter, the larger the volume that can be processed, but at lower intensity. High gain probes produce higher intensity
than standard probes of the same diameter, and are usually recommended for processing difficult applications. Probes are
fabricated from high grade titanium alloy Ti-6Al-4V because of its high tensile strength, good acoustical properties at ultrasonic frequencies, high resistance to corrosion, low toxicity, and excellent resistance to cavitation erosion. They are autoclavable, and available with threaded ends to accept replaceable tips, microtips and extenders.

* Connecting stud 1⁄2 - 20. Available with 3⁄8 - 24 stud to enable connection to a 20 kHz converter manufactured by another company.
** Do not use a probe with a replaceable tip when processing samples containing organic solvents or low surface tension liquids.
Use a solid probe instead. See caution on page 8.
*** With the amplitude control set at 100%.
† Because ultrasonic probes are tuned to resonance, their length may vary slightly due to variations in the titanium’s
modulus of elasticity.
Note: With the amplitude control set at 100%, the amplitude at the converter tip is 16.5 micrometers (.0006 inch).
