Probe sonication is highly effective for processing nanomaterials (carbon nanotubes, graphene, inks, metal oxides, etc.).
Sonicators have become the industry standard for:
Particle size reduction
Particle synthesis and precipitation
The Sonicators are the most effective units for nanoparticle applications. These models can be used with a variety of powerful probe options which can process samples quickly and effectively. The key detail to discuss when considering a Sonicator is the sample volume range. The sample volume indicates which size probe is required.
When used with a standard probe, these are routinely used to process samples up to 1.5 liters. This can process up to 40 liters. Flocells are inline processing accessories which can be used to process up to 20 L/min. Flocells are available for each of these 3 Sonicator models.
Solid tip probes are required when organic solvents are used with the nanoparticles. Aqueous samples can be used with replaceable tip probes. Most nanomaterials require extended processing times and high amplitude settings so microtip probes are generally not recommended. Due to this, the use of microtips, as well as smaller Sonicator systems, is only recommended on a case-by-case basis.
When working with volumes under 1 ml or very expensive samples, a Cup Horn (indirect sonication method) can be considered. Cup Horns prevent aerosolization and cross contamination and may be beneficial to certain sample types.
Probe Sonicators versus Ultrasonic Cleaner Baths
Probe Sonicators are many times more powerful and effective than ultrasonic cleaner baths. A cleaner bath takes hours to accomplish what a probe Sonicator can do in minutes. Please see the following article excerpt:
It is clear that MWCNTs are not completely soluble in water by using bath Sonicator for 8 hrs; there was much sedimentation of MWCNTs at the bottom of a small bottle. Upon operating 20 kHz applied by a probe Sonicator, the MWCNTs are entirely dispersive in aqueous solution, forming a homogeneous-free solution. Remarkably, there is no sedimentation observed even after four months of sitting at room temperature.
